Crevice  Gardening ......in defence of rock.....

In another thread in the General Forum section " Denmark's giant crevice garden... how it was made...."
 http://www.srgc.org.uk/smf/index.php?topic=4462.0

 ....I mentioned an article from the Rock Garden Journal of 2003 written by Zdenek Zvolanek.
ZZ has  kindly given me permission to republish that article here and he will add some comments and more photos. :)

I will begin by this posting, where I will attach the 2003 article, broken down into four sections to allow for the Forum posting size restrictions.... they are in pdf format for easy download, to print or enlarge at will.....

CREVICE   GARDENING

  One top American musician (trumpet player like me) told his audience in the Prague Conservatory, that very important for your progress is to listen the performance of  maximum of good players in your free time.
I think that the same is in the case of a constructor of the rock outcrop.
 He (she) must see (and study) the maximum of rock works from different stones and from different designers.
 My plan is to show  some of my designs and also the ones from another constructers to compare.

 There is very contrasting feeling if you see an outcrop towards Side-Walls (optic illusion of one compact rock) or towards Faces of Layers (not so perfect, sometimes little bit a busy; depends on the shape and the thickness of the layers). The best Main View is towards Side-Walls.

When you concentrate your effort of an older experienced individual, you will probably build your last stony outcrop. It must be in your eyes aesthetical sculpture (if not, you have the freedom to improve it towards your own “picture”). It will be first a silent beauty but after processes of planting and replanting with lovely flowers, this dumb lovely rock would start to speak and then:  it is the classic antique story of Pygmalion in your own small theatre with long lasting happy end.

Now to Northern Ireland

Margaret Glynn is marvelous woman in our rock gardening circle. She perfectly organized rebuilding of small rock garden a representative of Ulster Group of the AGS in Antrim.
Antrim is Forum Hero Mark Smyth’s headquarter and place of the Ulster Show too.

The place, which the Group obtained in the large garden of the local horticultural college, was squeezed in one corner, but I tried to raise it with small stones maximally up just to be seen.
Margaret organized large trailer and I was able to select and load some suitable stones in a 200 miles distant quarry including chippings for top dressing. If you do rock work in the rain it is fine to be at a sand hill. Sand is not sticky like a soil.

I believe that many Saxifraga cultivars (from Ron MacBeath nursery) will enjoy this sandy root run and I hope that Mark Smyth can direct his powerful Canon to show you the progress there in following spring.
I did not see a picture of this wee outcrop in flower. Mark is
fiddling around his pots and ignore something important close to him. :-X  It
is a pain not to see one of my babies growth! 

We bought also plenty plants (including dwarf rhododendrons) from one famous Irish nursery.
The Rockwork was organized as a work shop for college students (and lecturers too) together with a lecture about crevice gardening and its plants. Students did planting and topdressing of the outcrop under my conducting. Margaret also managed elegant black labels and pen with silver paint.

Some of the ancient writer wrote that only one of ten women is coming from a bee.

Yes, Margaret Glynn is of honeybee origin, Maggi Young, off course, too and we must have a peek towards another woman born of the bee (the owner of two rock gardens) Joyce Carruthers.

One crevice garden in Victoria, British Columbia and one steppe garden in the Czech Karst and you must be busy honeybee (the transatlantic subspecies). Her functional (blooming) crevice garden in the Maritime climate (dry summers and wet mild winters) is good example that this growing technique is right (may be superior) when you are not present for half of every year in your garden. Here are some pictures from this Canadian artificial outcrop from crystalline metamorphic schist and Czech Karst steppe with Joyce milking her babies.

What a job to celebrate females so nicely!

BACK TO NORTHERN IRELAND
After lazy morning I played hide and seek with old photographs to
decorate a tribute to June Dougherty from Ulster.She is the lady in
black.
June Dougherty (see the above Mark’s remarks about the fields of snowdrops of June) belongs to the same class of hard working females. She is running with some help an old private garden of the country estate size with lovely old ancient trees, perennial and bulb beds under rhododendrons and camellias. I made for her one large rock garden from the rare superb Irish limestone (I had not enough stones so there is seen unfinished broken top) one large raised bed covered with recycled slate pavement and a series of low outcrops from schist. But it was long time ago and I would be pleased to see progress of the plants planted there.

Mark: your friends are calling to you


VERTICAL  “STRATIFICATION”

 

   It is known, that stratification of layers of mud etc. at the bottom of the ancient seas was horizontal. My first picture is very rare (Northern Maritime Alps in France) and it is example of side pressing and folding the limestone layers into whole synclinal. You can see their very steep stratification. Second picture is from old small limestone quarry (2 miles behind my diabase rock) where is seen vertical cliff formed from layers folded vertically. You can see there many bottoms of layers (beds), which I call for easy understanding the side-walls.

Great thread. Good to see these pictures.

May I be so bold as to make a minor (technical) correction to the last post (and apologies if this may seem pedantic.....). In the superb picture of folded limestone beds from the Maritimes - this should read "anticline" instead of "syncline". Anticlines have beds inclined away from the crest of the fold, whereas in synclines the beds dip towards the axis.    :D :D :D

Also, a point of note for British readers: the rock name "diabase" is not often used here where the equivalent term is "dolerite".

Pardon another nerdy geology comment, if you will... :)
Given that it seems the Alps formed by collision of plates and thrust faulting (same as the northern Rockies here), it is puzzling why visible evidence of such folding would be rare?  It's very visible here, with vertical and recumbent anticlines forming the peaks of many mountains.

What an excellent, inspiring thread!  I can see I need to get a few tonnes of rock in, and overhaul the entire yard!

CREVICE BED IN PERSHORE

 

   When my old friend Ron Beeston was responsible for the show garden of the Alpine Garden Society in Pershore, he organized rebuilding one experimental bed into proper crevice bed there near to the large naturally designed scree. Ron was perfect in getting suitable stone, some special English kind of sandstone forming desks. He prepared big heap of soil mixture with professional care of retired nurseryman and he managed great amount of suitable plants from different sources. I had excellent team with Alan Furness and John Page (to mention two known stars) and other members of the AGS so the work was smooth. We planted plenty dwarf Daphnes including golden yellow Chinese D. calcicola ´Gang Ho Ba´ and only one daphne died there. Crevices in full sun all day are what make them to be compact and happy. I saw them yesterday at the AGS web site. The same success was with old trustful cultivars of Saxifraga the section Porphyrion.

The only mistake was that Ron from some important reason ended his function for AGS and so all the outcrop, which was supposed to be patiently finished with sand stone flakes hammered into crevices was quickly covered with round unsuitable chicken grit. I have only two photographs taken after one year after finishing and one with Saxifraga ´Southside Seedling´ from Ron Beeston. One Dane visited Pershore in a cooking summer weather and he told me that all garden plants were looking tired and wilted but the residents of crevices were looking fresh. What a relief !

#B: It is possible to make plants grow in horizontal crevices as well.   ;)

The first picture is from around 1970 the second 1959. The rock is orthoceratitic limestone. Unfortunately my long spells abroad obliterated the plantings - maybe I will be able to redo them.

THE DOLOMITES
Doctor Rock was very polite to my error with the anticline (the syncline is precisely upside down) and I would like to be the same to young boy Mark Smyth and to explain him a few fine rules of rockwork.  We never try to imitate dramatically dissected (weathered) mountain ridges for two reasons: it does not help to our cultivation of alpines and in small scale of a trough or a small garden it looks unnatural. In the garden and in the trough we construct small outcrop with layers appearing naturally above terrain and then they must naturally disappear into underground (this is called natural return of layers). We feel imaginative arc above the highest layers of the outcrop and no rock has permit to protrude through the arc because it will be against natural weathering of the rock formation. Smooth gentle surface of the outcrop (or a head) is always elegant! Mark, I like your rock under Hypericum much more than your mini-tre-cime. I illustrate the idea with one mountain picture and ask you not to copy the back ridge but the shape of the front part.

VOJTĚCH  HOLUBEC

   This quiet gentleman spoke in England, Scotland and USA about rock gardening. He is agricultural expert and botanist by training and for the last 15 years one of the Czech best seed collector. Vojtěch wrote about two decades ago Czech handbook about rock works (together with Ota Vlasák) and he will be one of the speakers at Alpines 2011 (his subject are plants from Central Asia). He was one of the first constructers placing rocks in angles slightly tilted out of the vertical position. I assisted him with sandstone desks in Dortmund (together with Josef Jurášek) and learn the basic tricks. Another assistance was in our Show garden in Prague where the brave tilt of heavy limestone slabs started to go slightly down (after 7 winters) and I had to support it with block of stones. But tilting layers towards a slope is safe from frost actions and very naturally looking. Now you can see samples of Vojtěch´s designs in  following post. The fat limestone layers are in his home rock garden in Prague.

I think that people will love Vojtěch´s romantic style,
but fat layers and plenty "dwarf" conifers are strongly restricting
amount of alpines there. Romantic rock above water are good for dancing
around but not easy to maintain if you are arthritic oldie. Joyce says
that it is a paradise for breeding moscitoes.

OTA VLASÁK THE OLD MASTER OF ROCKS

Ota Vlasák adore robust stones and they give him the love back because he is treating them nicely with his professional hammer.
He was boxer, truck dispatcher in huge building company and professional landscaper. At present he is retired and permanently busy.
I assisted him once to reconstruct part of the large Prague Show outcrop and I was not able to discover the principle (or method) of placing granite stones in the construction. After one year of thinking I discover that he is using the principle of steep stratification of sedimentary rocks for his fire born rock.
Well, his bold ridges are standing 25 years in continental weather without a movement. Rocks rooted into his garden. The method is to stand the best large rocks into triangular side-walls and behind them place slightly parallel stones to form very eroded ridges. His granite is softer and some rocks can be crushed with hammer into perfectly matching topdressing.
One of his great qualities is sense for details. His discipline is careful closing crevices with help of hammer choking rocks and plants.
Top quality topdressing is his strong weapon.
I am obliged to present for the FORUM  SHOW some of his designs.

i suppose in the end, the only thing that matters for any garden is that it provides a habitat for successfully growing the types of plants intended, and that it makes the owner/stakeholders happy ;)
(of course defining both 'owner' and 'happy' owner  public gardens is another issue, which is why i added the complicated word stakeholder;private gardens are easier..)

Kata, what a good example of how a garden can be made in the smallest area.
I agree with ZZ ( lucky for me, eh?!! to agree with the Rock Master ;)) ... we can see in pic 4 that the planting level is rather low between the rocks.
This might be because you did not fill the substrate high enough to begin, or that you did not pack it firmly to minimise  the settling of the soil.

 If you look at Ian's trough making, you will see photos of how full and high the soil/sand must be before planting.

 But these are refinements that come with experience and your garden is really lovely!  8)

By Jove she is from Canada, I really had no idea.  She was born in London, Ontario - a long hike from here.

Wikipaedia says "With her studies disrupted, St. John took the opportunity to travel throughout the former Soviet Union and Eastern Europe. During that time she encountered and lived with the Roma people, a cultural experience that would later be reflected in her 1997 album Gypsy."

ALAN FURNESS THE KING OF BRITISH CREVICE BEDS

   The readers of the AGS Bulletin know Alan Furness as the master of the scree techniques and the holder of The National collection of Celmisia. I witnessed his perfect work with pieces of sandstone in the Pershore project. He is a professor by profession but he use hammer and chisel with bravery of a stonemason.
 I also heard and saw his lecture about crevice gardening in N. Ireland and it was superb delivery. Alan built his crevice bed with surgeon preciseness, with wisely designed paths for the intimate access to his crevice plants.
I own only one picture with a fresh rockwork and planting but everybody can see the happiness of his plants in this construction made from sandstone. Because he loves to grow Himalayan Androsaces he invented method of planting young seedlings and cuttings into ultra thin fissures. He split stony desks with special chisel to have lovely chinks and he fills them with a brush with dry silver sand and inserts fine roots of androsaces during the filling. Saxatile androsaces need cultivation in narrow crevices like many true alpines.
I hope that Maggi or somebody else can ask him to show his crevice bed with older plants at this Show.

QUIET MAN IN CZECH KARST

  This Show of Maggi Young (some Russian wrote song Oči čornyje- Black Eyes after being inspired with this woman) will be uncompleted if I miss Milan Čepička and his two outstanding limestone outcrops. His brother is active Czech member of the Prague Club of Rock Gardeners (growing Iris elegantissima outdoors) but Milan is a solitaire sticking to his small garden and job of car mechanic. He collected in local fields and forest smaller limestone pieces and put them together with divine talent for naturally looking outcrop. He had between two outcrops a path paved with concrete square desk and I asked him to put some layers of stones there; the effect is seen in one picture. He is slowly improving his assortment of plants. Pictures are from Calgary (The Fergusons).

ZZ, it has been my pleasure to tempt you along this particular garden path! :-*
It seems our walk together is enjoyed by many others too which is a delight to me.

Your words to me are too kind..... for my eyes are green .... but it would be grand to be the subject of this fine song.... sung in this instance by Feodor Chaliapin, whose version is perhapsthe most famous........ with this wonderful chorus.......a Magnificent thought!!

Dark eyes, passionate eyes
Burning and splendid eyes
How I love you, how I fear you
Verily, I espied you in an ill-starred moment .....

I imagine they would be very heavy by the time the pot is finished. Do you place your pot before starting to add the soil and rocks?

JOSEF JARMILAE HALDA
 The most known foreign constructor of crevice gardens in USA is Josef Halda (the neighbour of Jaromír Grulich in Sedloňov).
He wrote monographs of the genus Primula, Daphne, Paeonia and Gentiana and he was one of the best Czech seed collectors.
Josef was the first man in human history building plenty outcrops with steep stratification (always in an angle about 45°) starting in 1970. I was his assistant with building show outcrops from granite stones keeping precisely three different angles of the rocks and their joints. I learned a lot. Josef pushed me to write articles about alpines and I platonically love his wife (top artist Jarmila).
During the Czech Conference he showed us one rock garden with his design in Orlické Hory (Eagle Mountains) where you can see action of strong frosts to the stones in the angles 45° in one picture.
This is one of more reasons that I keep vertical angle of layers, which are in this position frost resistant.
Josef stands with blue jeans in the middle of another photo but to show him better, I photographed his portrait (in the middle of the Primulaceae family) made by Jarmila Haldová.

 AN ELEGANT ENDING
   Every clown must have the right sense to end his performance at the peak condition (after that great moment the vital vibrations are (by the physical laws) slowing down) and let the maximum of impression behind him.

 Thanks to the international audience to give me support, which I badly need to write something sensible in a strange foreign language (I had only Czech and Russian at school) and somehow do my best. I let behind me tons of stones and minimum of flowers so something here is out of the balance.
 Now there, in the end of the long rope for pulling the rock gardening forward, it is your own playground under sharp spade of our moderator (see Joe Halda´s skill for chopping every terror) and I must start my long journey to find some new and golden thread hidden in the distant mountains or somewhere in a deep crevasse in my mind.
One flower is here supporting my cordial thanks to the lucky owner of emerald green eyes.

Thanks for that advice Zdenek. I was thinking of schist actually, approximately the same colour as my troughs and superbly lichened and weathered. There's masses of it in an area just an hour or so away from me.

On the other hand I have a collection of limestone slabs which though too big for the troughs would make a good small crevice garden somewhere nearby. I think they were originally paving stones but never used and when we moved from our previous place we brought them with us "just in case." :) There are about 30 I think, overgrown but retrievable and well weathered already. (They've been sitting there for 12 years.) They are approx 10cms thick and about 60-80cms square, more or less. If the garden were not to be very high, they could be broken in half and so make twice as many of them. I have some limestone troughs too, carved out of the natural stone, quarried in blocks and a lot of long limestone bricks (to the top and right of the pic below)

IRREGULAR  IGNEOUS  ROCK (Post Scriptum to the Show)

  I must share my spring (2009) struggle with nicely colored but badly shaped stones in Southern Austria near Graz. Fritz Kummert, the star of hybridizing Daphnes, gave me very limited space around his new alpine house.
We got lovely mineral sand-like soil and the local stone.
The only way how to work with this kind of stones is again to try to set them into layers of different width, parallel each to other.
Fritz got a lot of crevices (the rockwork goes around the alpine house) but I have fear that he will put taller plants there because he is gardener loving all unusual (curious) plants.

Thanks to you both. I did look at those but seem to have missed the lower one, or at least its significance. I see what you mean Zdenek about the right angles. Of course the rock work will be done by me and maybe Roger, not by Vojtech so the result won't be as good, but I see that such an arrangement makes for a sunny side and a perhaps damper, slightly shaded side, or at least away from direct heat.Two aspects making for a different or extended range of plants. I wish I'd done all this 40 years ago when muscles, back, knees et al, were all in better working order. :'(

It has given me enormous pleasure to see posted images of Zdenek’s latest mind- blowing crevice creations and I am told that the task of planting up his latest example at Bangsbo Botanic Garden is a 2-year project. Pictures give a good idea of the forces employed in what is only the first stage leaving planting and infill or topdressing in the hands of the delighted (or awestruck) beneficiary.
It has been my good fortune to visit the Czech Republic on several occasions and to see unbelievable work by a growers who were pioneers in the work. I mention only two:
(First two images)
Ota Vlasek makes beautiful use of granite and the first two images try to illustrate the vertical stratification in relatively small outcrops. Perfectly matching  “rotten granite” packed into crevices and for the topdressing give a perfectly natural look to this very large rock garden. Ota told me he had spent two whole days planting and packing an area of one square metre of the rock face.
(Second pair of images)
Milan Cepicka has filled his relatively small garden with limestone (I would guess about 20 tons) and I will let the camera speak for me. This is a case of art concealing the crevices and I think this man should placed in front of camera so that his skills may be captured as a master class
Returning home Zdenek employed basalt across the Irish Sea and Derbyshire tufa in my own garden (another story) but so far as I know sandstone elsewhere. I am not experienced enough to know of the whereabouts of the considerable amount of the crumbling, splitting sandstone (which Z would describe as flakes) required for filling purposes and the small amount
available from the quarry for the Pershore project was sufficient for only a little over half the task. Enquiries elsewhere were fruitless. I illustrate what we did achieve through the work of an inspired hand but unfortunately I left the scene before investigating alternatives, which included the possibly futile task of the breakdown of larger stone. A more satisfactory plan would probably be to follow Alan Furness’s route with a matching sandstone aggregate although I am waiting to see if the surprising choice of a standard potting grit by the AGS may prove the more satisfactory of all. My opinion is that the unselfish work and craftsmanship of a Czech master deserves in return all the art and skill that can be mustered to ensure that with age it look as if it was a natural creation.

CREVICE GARDEN IN A HAT
We must stress that Mother Nature has better ideas than human
designers.
 Mother Nature sometimes designs quite interesting construction for forming our ideas. This one is made from vertically cracked basalt and has local name Hat Rock. The idea is that you can go round your outcrop, which has all possible aspects for different taste of plants. If you follow the Nature, do not construct it so high.

A very warm welcome from southern rock gardeners too, Mr and Mrs B.  I remember with great pleasure the one visit to your Pershore nursery, in 1993 and am happy to say I still have most of the plants I was able to bring home with me at that time. Since then, the whole process of importing live plants as distinct from seed, has become an impossibility, which makes those from that time, the more precious.

I think that we can show one happy senior rock gardener
with new alpine house and a crevice bed. Austrian plantsman Fritz
Kummert just today send me interesting information about really small
Narcissus together with a cute photograph. My Czech bulletin Skalnicky
will share the pleasure with SRGC Forum and we wiil wish Stefi and Fritz
long lasting happiness.

Here is Fritz' comment on this little Narcissus:
Quote
Narcissus cantabricus DC. ssp. monophyllus

  After information from Spanish Narcissus specialists there are more than one species involved in what is called Narcissus cantabricus. The naming of this species was from the beginning an error, de Candolle’s herbarium-sheet was labelled to hail from “Cantabria”, but no white hoop-petticoat grows in this region!

  Flora Europaea ignores the subspecies monophyllus, which is found at the Puerto de la Virgen and around the Santuario de la Virgen in the Sierra de los Filabres. It is a plant of crystalline rocks; a typical companion plant is Cistus albidus. The soils in which subspecies monophyllus occur is typical very shallow and stony. We saw it on two occasions in full flower: 2000 end of February and 2009 end of March. The small spherical bulbs lie not very deep in the ground and possess in most cases only one thread-like leaf. The sight of thousands and thousands of these glistening white flowers is breath taking!

  After my experience this small narcissus cannot be grown in the open ground, it is a plant for the alpine-house. Propagation takes place by division of the bulbs, which is slowly with some clones, or through seeding. Seed-set in the alpine-house is good after artificial pollination. It lasts at least three years from sowing to the first flower!

I wish you could have seen the rocks in the area where yesterday Roger and I collected some small pieces for my new troughs. It was near Middlemarch, the beginnings of Central Otago and the landscape is typical of many parts, dry, brown and dusty with small to massive rock outcrops almost any one of which, if transported complete, would make an outstanding rock garden at home. Where we were the crevices were layered horizontally rather than upright but in the troughs, I'll try the upright kind. The rock itself is schist and tending toward being quite rotten with flaking even at a touch sometimes. I brought home pieces that are approx 30cms long in the main but as I unloaded them, I was sometimes left with slivers in my hand, a bare millimetre or two in width. I can use these to put between larger pieces and so make the crevices narrower.

I'd have taken more pictures but the wind was so gusty we could barely stand and poor Teddy was bowled over and blown along at one stage. When we went into Middlemarch to get some coffee we saw an elderly woman swept from her feet and crashing into a fence. A terrible day with frequent short bursts of driving rain and hail as well. The drive there and home again was quite frightening with Roger barely able to hold the car on the road sometimes.

I love the idea of incorporating the alpine house into a rockery - often glass house buildings themselves are so stark from outside and this one will blend in with the surrounding landscape - I look forward to seeing more of how this venture develops....

Zdenek visited this garden a couple of months before the first of the crevice gardens was started.  A steep hill beside a small cliff had been terraced with stone walls so the side walls were already in place and the main crevice lines follow the exposed stratifications of the back of the cliff.  The first crevice garden was finished by the summer of 2009 and planted with a wide range of alpines and rock plants, including a number of Daphne x hendersonii forms.  The main problem has been deer walking over the garden this winter without enough snow to protect the plants so it has been covered with chickenwire for the duration.(http://)

Thanks, Maggi.  Yes, my name is Anne and not Astragalus.  My garden is located in the Hudson River Valley in New York State, but nowhere near the benevolent river influences.  The site is steep, rocky, cold with harsh winds much of the time - a delightful place for a rock garden.  Our western phloxes are among my favorites (behind all the glorious peas).  If I can ever figure out a reasonable way to post pictures I'll send some of the phloxes.  Do you grow many of the western ones in the UK?  I've been admiring the plant pictures posted, really beautiful.

Anne, the cushion phloxes are quite popular here.... in a crevice garden or trough setting or pot grown ( whether for exhibition or protecxction is certain areas)

The Mexican phlox need alpine house treatment mostly.

Post by: astragalus on January 29, 2010, 01:33:30 PM
Hi Maggi, everything here is grown outside (no alpine house or greenhouse). Unfortunately, the Mexican phloxes are not hardy.  I'd love to hear the kinds of plants people are growing in their crevice gardens.  The natural rock here (and the whole place is mostly rock!) is a very well-cemented sandstone nicknamed "greywhacky" by geologists whho had to "whack" it very hard with their hammers in order to break it.  There must be close to 100 steps in the garden and they are all slabs of granite or rough slabs of limestoen, thus breaking one of the "rules" about using stone in the garden.
"Greywhacky" simply doesn't break evenly like granite.  You can spend a lot of time working on it and end up with a pile of rubble.

Hello Ann, what I wouldn't do for a magnificent outcropping like your "graywhackie"... love the Epimediums at the base.  Check out the epimedium thread if you like "eppies", as I call them.  http://www.srgc.org.uk/smf/index.php?topic=4769.0

Years ago when I lived in the Seattle, Washington area, I did grow a number of the Mexican phloxes outside in raised sand beds, they did fine. Haven't tried them here in Massachusetts, although I suspect they would not be hardy here, and they are harder to come by these days.

Whenever I travel from Massachusetts to Maryland to visit my wife's family, crossing the Tappan Zee Bridge, viewing the huge rocky bluffs on either side of the impressive Hudson River valley, I always wonder what it would like to live and garden in that area.  I understand you're not directly facing the river, but just wanted to say, your photos of rock garden construction are inspiring, this is an excellent thread.

Mark, nice to hear from you.  My garden is a series of stepped ledges ending in a small cliff.  It faces WNW and is exposed to all the winds of winter.  Windbreaks are not possible because of the amount of rock and lack of root space.  We have some large trees but very widely spaced.  I tried the Mexican phloxes when they were first popular - none survived the winter and after three years I gave up.   I really prefer the phlox from the Rockies etc anyway.  
Harold Epstein used to bring me epimediums every time he visited the garden and I'm very fond of them.  Actually, this is a garden with very little shade and Harold always brought me wonderful shade plants (double trilliums, Iris gracilipes, Glaucidiums etc).  Maybe he thought he ws giving me a challenge (he was!) but I was always nervous when he visited lest he find one of his gifts dead.

Hi Cliff - Drilling this rock (however you spell it) usually ends up with a mess.  There are a number of nice crevices and if I could only clone myself I would have the time to clean them all out and plant them.  I did do that for a draba which worked out nicely.  Still don't have the hang of posting more than one picture.

Anne, those outcroppings are massive, I'm envious.  I think I have as much rock here, but it is all a few inches under the soil :o!  The ledge filled with Phlox borealis is a fantastic sight.  It is one of the best species of Phlox, better than P. subulata because it keeps such nice dark green foliage even after flowering.  I grew it for years (originally from SRPN), where it grew side-by-side with Hypericum buckleyi, one of the south eastern dwarf woody hypericums.  They both flowered at the same time and made a memorable yellow and pink combination.  Both are long gone here, much of my rock garden plantings lost to neglect during those years where my two daughters were small and I worked too much and commuted too far and life was too hectic.  Your photos are strong inspiration to start again.

Regarding Epimediums and Harold Epstein's choice woodland plant gifts, at least with Epimedium, I find many grow perfectly well in bright light to full sun.  When I was working all these many years, I was rarely around to water the garden, so the "eppies" had to withstand dryness and neglect, which they do admirably. Even Iris cristata will grow and flower in full sun.  Now Kirengeshoma, they're another story... and after a decade, finally found a spot where they don't collapse daily from heat and drought.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on January 29, 2010, 04:24:22 PM
Mark, I agree with you about Phlox borealis.  It is one of the earliest things to bloom here and it's such a good doer.  It has never been watered, is out in the blazing sun and takes wind in stride.
The epimediums seem to be very tough and the E.grandiflorums seed themselves nicely, doing your work for you.  I wouldn't want to be without them and yes, they seem to do well in a lot of sun.  The epimediums in the picture I posted take the full wrath of the afternoon sun and do OK, ditto dodecatheon meadia and Haberlea rhodopensis.  The last was a surprise.
  The story about "greywachie/greywacky/graywacke") was told to me by the geologists who mapped the rock here as part of a New York State mapping of rock formations. Perhaps it is apocryphal but I always liked the explanation and can attest to the difficulty of breaking the stone.

Post by: astragalus on January 31, 2010, 03:36:29 AM
I do grow a lot from seed but not because of thin soil. It's difficult to explain the situation here.  We've found fossil rocks with shells.  This was all covered by a glacier which, when it retreated, left part of the stone as smooth as satin but with glacier scratches which you can still see. The middle part of the ledges was totally buried when I started gardening. I hit a submerged ledge with a pickaxe.  When this happens, your shoulder and elbow immediately tells you you've hit ledge.  I decided to explore and uncovered the buried ledges. They go straight down for a few feet and then you find that the water etc carved the ledge underneath at an angle.  Following that angle (roughly 45 degrees if I remember correctly) for the length of the tool plus arm, you have about 8' depth of soil which was clay and rock and was all dug out and replaced.
This seems to be true of all the ledges.  That area remains cool and must hold moisture because everything there has done well with no watering at all. 
I just switched to digital in the last year and most of my photos are slides. 
The following are the best I can find of the digital photos.

Jiri, your pictures (and garden) are wonderful.  Great that you have taken pictures as you go along, I'm always forgetting to do that.  It looks beautifully planted.  Can you tell me some of the things you have planted? And what has worked well for you?

Anne, your garden and rock outcroppings are so natural looking and scenic, and beautifully planted.  Your story about excavating and uncovering buried ledge has me totally stoked!  I wasn't joking when I said most of my property has stone and ledge just a few inches to a foot below the surface.  Years ago when I had a backhoe come in to dig a 200' long drainage ditch, they hit lots of ledge, and I had them put some of the largest chunks over to one corner of my property, the intent being to build a rock garden there one day.  In the same location, there are areas of exposed ledge, and I have always wanted to excavate the area to reveal the ledge.

Now please don't laugh, but I have uploaded a photo taken almost 6 years ago from my deck (which was still under construction at the time), looking towards the part of the yard I describe, with some fairly huge ledge chunks are placed.  I added an arrow on the photo to show the small area of outcrop.  As soon as the spring thaw arrives, I need to start digging.

Post by: astragalus on January 31, 2010, 08:38:50 PM
Hi Mark,  I'm so not laughing!  It all sounds perfectly normal to me.  It took me almost five years to dig out the middle ledges and I dumped the clay and debris over the front cliff.  I can now drive the tractor on to what used to be empty air.  I hit the ledge when I wanted to put two or three steps down to a lower level.  Famous last words .."This looks like ledge ...let's just see where this goes".  I'm not sure if it was gardening or mining, but it gave me three new levels. The soil was a sticky, heavy  clay with lots of rock.  All the rock was saved and the clay dumped.  I'm not exactly weak but it was difficult to lift a full shovel of the clay when it was wet.  Then I learned that the time to dig was when it was frozen.  All the water became ice crystals and you could cut it with a hatchet like turves of peat.  Big frozen slabs would be cut and thrown into the tractor wagon and dumped. All I had to do was wait for the ground to be free of snow.  Unfortunately I spent a couple of years digging the hard way before this was discovered.
Your slabs of ledge look beautiful.  Do you have a bobcat to move it?  What kind of rock is it? Sounds like a wonderful project and I hope you will take pictures as you go along.

I am not so lucky to have any natural rock here, but plenty of pebbles (so I carry all stones with my sons or alone on a small trailer). It should carry 500 kg, but I am quite sure it had sometimes almost double weight, as I couldn't resists to take all nice stones available. I have also layer of clay below, very good source of water in my dry environment, for plants rooting through crevice constructed above. I can confirmed that for example some daphnes they first have very very slow development, but later on they grow suddenly much faster. I don't have many pictures from this new garden and too many plants are still in pots, suffering from my poor treatment. I can confirm so far success in crevices with daphne cneorum (various forms), arbuscula, circassica, juliae, x hendersonii, x schlyteri, x sundermannii, x rollsdorfii, x susannae.
One picture shows troughs, better say pieces of troughs, raised on the wall to frame the artificial north slope to get some cooler positions. I am also trying to consider comfort for observing plants. Pieces of troughs are cheaper and also easier to transport. Later on all spaces will be covered by plants or stones.

Lesley,
here is some development I managed to finish before winter. Very often not all 4 sides of trough are needed, as you can cover missing part with crevices. Or if trough is broken in 2 complete pieces, you can just put them together and don't need to drill drainage hole. I am saving money as often I pay just 50% or less. Also weight is much smaller. I love to went through antiques here and looking for suitable troughs. In a spring I will continue and add some better pictures.

Jiri, your pictures are stunning.  I'm very interested in your last pictures showing the construction in progress.  Your crevice garden seems to slope downwards completely.  What will be the effect on it of heavy rains?  Or is the slope not that steep?  It's always difficult to see from pictures.  I'm attaching a picture of the site of my crevice gardens.  The first garden would be almost at the top where there is a trough on the left.  That sits on the front wall.  The crevice gardens here are walled on all four sides.  To the left by steeply sloping rock of the cliff, to the right by the small side walls of each terrace next to stone steps winding up to the top.  The long sides are the retaining walls. I ran the crevices the long way because it mimics the natural crevices of the cliff. Because there is quite a drop from the back wall to the front wall, I made the building process easier by stepping down the crevice walls in only one place with my work path inbetween.  That way both the front and back crevices are level, and everything can be reached with a little stretching.  Above the topmost wall which you can't see in the picture is the back end of the cliff with huge crevices.  That will be next year's project hopefully.  I hope the picture shows everything better than my words even though you can't see the start of the first crevice garden which is now finished.

Well, I spotted the "tweedyi" right away.  When I lived in the Seattle Washington area, it was a mere 2 hour drive to get up into the dry Wenatchee Mts (a spur off the Cascades), where there was lots of L. tweedyi, but in some strong yellow and peachy-yellow shades (the guys at Grand Ridge Nursery found forms that were yellow strongly tinged red).  From there we'd move along to another area, and my wife and I would go "rediviva" spotting, along with Fritillaria pudica, Sisyrinchium douglasii, eriogonums and penstemons... all the good stuff, and astragali too, but the most memorable plant is Trifolium macrocephalum; dwarf but with enormous heads in orange shades rather than the more typical pink, but nearly ungrowable as I've tried it.

Loved the Trifolium pictures, Mark.  The pink form is really two-toned which is lovely. My favorite is probably Trifolium owyheense - no picture, it got eaten by a critter.  Isn't it amazing how they always find the best? How lucky to have seen Lewisia tweedyi in the wild. It seems easier here than L. cotyledon. Attaching a picture of a pink form of L.tweedyi which seems to be reliable here.  Maybe you have seen ones redder or pinker than this in the wild?

I'm very interested in your last pictures showing the construction in progress.

Anne, I see we have the same dreams  :D
I have added few more pictures. Like you, I have in mind, that I have to be able to access plants without acrobatic positions on rocks in a future also. Each path is framed with first line of stones. They have to be carefully fixed in the soil, as they will support the others.It is better if the angle is little bit more then 90 degrees, going slightly backwards, so stone pressure the soil behind. After fixing first line, I add another one. I always put or hammer in crevice smaller stones having roughly the same thickness as crevice. If it is not solid enough I hammer there with rubber beater small stone slabs.In part next to troughs, I was able in 2 meters length to get upwards 1.5 meter.
Once all stones are fixed by smaller ones together and crevices filled with sand or soil, it is all very solid, similar effect like if you put together thin ropes or wires. You are right that in extreme positions sand can be washed away. I learned from ZZ to fill crevices there with clay. Other option could be piece of peat block used in Scandinavia or Scotland.
You have beautiful stones in walls , have you thought to change it in crevices too?

Jiri, thanks so much for posting the photos, they explain everything you are doing.  I can see many similarities and I see our differences too.  So far, my path has no stone and may not.  I always hope for seedlings and have found paths to be productive for this even when they are walked on all the time.
My crevice stones are set pretty much at 90 degrees.  The side walls are the terracing stone walls and they are quite thick and deep and incorporate pieces of ledge here and there so I don't think they can move anywhere. The crevice stones themselves are like mini ice bergs.  They are fairly large slabs and are set quite deep in the ground.  Hopefully they will not move at all. I can see we try and make our crevices the same thickness through much of their length and also vary the thickness of the various lengths.  I had a copy of Zdenek's little book with me when this was built and I kept referring to his illustrations and it was very helpful. Basically, every site is unique and requires unique solutions within certain parameters. It's what I love about seeing other gardens - learning how other people will approach the same thing. I'm not good about remembering to take pictures while working but have dug up some which may explain the split-level nature of the crevices on either side of the work path. You may notice some odd tools (like broken ski poles) but they come in very handy!I hope you will photograph some more this spring when everything blooms.

Anne, I see rebar being used in your second photo.  Is that just for temporary reinforcement until everything is backfilled?

My dear Doctor McMark, deductive reasoning! Notice trench excavated in front of rebar for next stone
that will support the unstable one once backfilled.

Yes.  Since a good part of the rock is buried it requires a deep trench - the rebar is perfect for this - also broken ski poles etc.  I like to do three or four rocks in a row to get a feel for how it looks so it needs securing in the meantime.

A Dozen  Pages Celebration

   A thread leading us through all the romantic corners filled with stones and plants, cemented together with the experiences of  authors, is actually the spine in the body of every good club of rock gardeners. This thread uncovered and showed more examples of artificial rock outcrops than is available in any official handbooks and will be a modern guide for every new grower interested in this most intensive kind of rock gardening.
   I now feel like an old male bull elephant going alone  into the mountains to allow the new family of the youngsters and clever mothers to run the art of life themselves. The big change in this fat thread is the strong and well illustrated contribution of Jiří Papoušek (my best Czech disciple) and Ann Spiegel the modern American plants-woman. They are both perfect top growers and independent lateral thinkers with the strength to go their own way (the best way for their very different microclimates).
  The construction of Jiri in his difficult flat garden is one which seeks for cooler north east and north west aspects for the accommodation of the true alpines. The framing of a natural outcrop with troughs is „modern art in rock gardening“ which could have followers or „old fashion aesthetic“ opponents. The important factor is his development of a functioning rock garden which pleases him and other knowledgeable grewers with his artistic achievement.
 The construction of Ann is a luxurious crevice bed  more suited to her impressive natural outcrop than the previous precisely made cascades of vertically stratified dry walls. The depth of the vertical crevices is superb; the mineral substrate used looks lovely and the flat angle of beds is functional against the intensive heat of sun in the local summer afternoons. The combination of the parallel pattern  with the angle of the solid paths for access fits into the category of modern arts, which is open to the never ending discussion of bearded theoretics. Her entry into our theatre is a pleasant surprise showing the international community in this Forum that innovative American growers are not yet extinct.
  I am anticipating seeing saxatile plants smiling happily at us from the crevices and fissures of both new constructions in the future. God bless this never ending thread and it´s followers.

Thanks for the help with the trough, Mark.  Currently in bloom in the crevice garden this crazy weather year: Phlox condensata, Phlox pungens, Oxytropis multiceps, Physaria eburnifolia etc.  I'll have to get busy with the camera.  These are all small plants (they have to be to plant them in these very tight spots) but they all seem to be doing well.  The only disaster was the new pen I used for labels with "indelible, lasts for years" ink.  All labels are blank and I'm depending on memory and visiting experts to i.d. some of the daphnes I planted last fall.

Ann, some beautiful plants there!  I particularly like the western American phlox, so many choice pulvinate species, the blue color on P. pungens is fetching.  Had to ask... with the photograph of Phlox 'Betty', I've been searching for the name of a "microphlox" with pink flowers, like a pink counterpart to the white 'Tiny Bugles'.  It is hard in photographs to impress upon the viewer with just how cute and minute the flowers are on these microphloxes, but the flowers are in such profusion, they completely cover the mats.  So, maybe my plant is 'Betty'.  Is 'Tiny Bugles' a Dick Redfield plant as well?  Do you think my phlox shown here growing in a trough is P. 'Betty'?

Please show us more goodies.

I've heard of 'tiny bugles' but don't know if it was one of Dick's. All these microphlox are great because you can fit one in almost anywhere.

Mark, that's Asperula sp. - the best I can do thanks to the indecipherable label written with special pen that withstands all weather - not so. That's basically a tear's worth of seedlings depending on my memory which is well honed for the peas but a bit fuzzy elsewhere

Re permanent pens. I used to use the Staedtler Pancolor F (Fine) in black and it lasted a full two years. Then they took out some environmentally unacceptable ingredient to make the Lumicolor pen as a replacement. It doesn't even last 2 months! So now I use an ordinary lead pencil, 6B.

Post by: TheOnionMan on June 09, 2010, 01:56:31 AM
Regarding labels, I have found the best and most affordable writing instrument is #2 pencil.  Over the years, I have used vinyl "pot stake" labels that I buy mail order from a company in Texas, USA.  They worked well because they maintained flexibility for their lifetime.  They were available in several colors, but the darker color green worked best, as pencil would fade less on the green labels than on the white ones.  They were of a size that could be cut in half, to double the investment mileage; shown are some in their original uncut shape, and others that have been cut in half.  I ran out of the green ones, and started using white ones of the same style.  Since then I ran out of these labels entirely, now using a different type of plastic label... these work except for becoming brittle much more quickly... must place an order to get another bulk shipment of these to last another 20 years... their minimum order is a certain number of thousands of labels.

What's interesting is, just a couple days ago I brought in some original labels to remake them.  See two labels shown at the bottom, the dark green one is still legible after 19 YEARS!  The white label below is the replacement.  Pencil on a matte plastic or vinyl label works, easily for a decade or more, never found an ink pen that was as reliable.

Thanks, Maggie,  I did read this already and still was not sure .  It certainly seems to be far less hairy than C. compactus and C.boisseri.  The label is unfortunately a blank and it was a label which would mean it was a "bought" plant as against something grown from seed.  I've looked over old catalogs from which it could possibly have been ordered and still no clue.  Whatever the name, it's very nice and tight and the flowers are lovely. Here's hoping for a visit from some expert who will take one look and say "of course, anyone can see that that's such and such".

May I first say that having stumbled upon this thread via a Google search on rock gardens, how enthralled I have been by the content! What started out as a quick bit of research has had me glued to my computer for the past two days. There is no doubt in my mind that what you have all created here must be THE definitive guide on the subject, written from the only truly reliable source of information - collective years of genuine, practical experience (you can't beat that). As a rank amateur on the subject of rock and alpine plants, I have been sufficiently inspired by the thread to have a go myself at building a crevice garden. I have built and planted dry stone walls before, and several basic rock gardens, so I am hoping that experience will be of some help. The site approximately 5m x 3m, flat, and south facing, on the front lawn of the house, butting up to the wall below the living room window. It has continual full sun, and the patch of grass I am lifting to place the garden has always remained obstinately brown, due, I suspect, to it being on heavy clay, builders rubble, and sewage pipes all below a very thin layer of poor topsoil. Not ideal conditions for a lawn, but hopefully good ones for the crevice garden!

I intend to use pennant sandstone for the construction, and I am happy with my design ideas which will - hopefully and eventually - make it look like the house was built onto the crevice outcrop (nothing wrong with being ambitious - or is it optimistic?). I really do need advice, however, on the substrate to bed the rocks into, and the material to infill the crevices and plant the plants in. Options seem to vary between "sand", "gravel" and "soil", none of which are particularly helpful descriptions as all three of these come in many different forms. I know that whatever I use for bedding the rocks in needs to bind together secure them in place, and whatever I use to infill needs to be free draining, but at the same time provide nutrients for the plants and not wash away in the first shower of rain. I also hope to have a good supply of stone shards for hammering into gaps, and a gravel that matches the sandstone for the top dressing. Finally, I was thinking of putting a layer of geotextile under it all, but I suspect that this might cause more problems that it is worth, especially as the site does not suffer from overly invasive weeds. Any views on this?

Can I throw myself on your tender mercies and ask for the benefit of your far greater experience? I promise, in exchange, to post pictures of the work as it progresses.

Many thanks in advance for your indulgence.

Hi Andy, a very warm welcome to you!
Your project sounds really interesting.... and darned hard work.... you do realise we'll all be looking for photos of progress etc??!!  :D

I know that ZZ is in the USA at the moment at the NARGS  meeting in Salida, so he probably won't be available to comment for a while, but there are others around here who have tackled similar building tasks so I hope they will be able to come up with useful tips for you.

I suppose, depending on the degree of the slope, that a fair amount of "shoring up" or terrace-type supports might be needed underneath the whole construction to anchor it?  ???
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Wildspirit on July 15, 2010, 09:08:37 PM
Hi Maggie

Thank you for the warm welcome. The project seems to have developed a life of its own and has gone from a simple garden project to terraforming. Still, never let it be said that I don't like a challenge!

The rocks will be, for the most part, vertical or leaning slightly back (according to the plan at the moment), so will need to be well secured. This will be achieved, at least in part, by using larger rocks buried deeper as periodic anchors, as well as rocks placed strategically at the bottom of the crevices to provide additional bracing. I am also considering using good old rebar... I also forsee at lot of trial and error...

Photos will be forthcoming as promised, just as soon as I stop panicking and start work!

Gulp

Andy

Andy, like you I am starting out new to crevice gardening. As Maggie indicated Zedenik generously mentored me as I developed my garden structure. The process was valueable and Zedenik's guidance aided greatly. He is generous with his passion. I am going to piggy back on your note with a question of my own. My bed is filled exclusively with coarse sand. Only a few plants are inas our temperatures in Illinois have heated rapidly. I anticipate the sand to be cooler than air temperatures below the surface. This has not proven to be the case as temperatures 20 cm down are running 32 degrees C about the same as the air. This surprises and concerns me. I am interested in hearing from others of their experiences wonder if these sub-surface temperatures will be detrimental long run. Any and all advice welcomed

Post by: Lesley Cox on July 18, 2010, 11:38:26 PM
I'm very surprised too Bob, at that high a temperature at 20cms depth. Plant roots could just about cook. I understand that growth of temperate plants stops at 24-26 degC. (Stand to be corrected, of course). While not in a crevice garden, my experience generally is that plants survive hot periods better when their roots are well moistened, rather than dry. In other words, things will survive boiling better than baking or roasting! ???
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on July 26, 2010, 01:43:42 PM
Maybe you're right, Lesley.  I've been using a very coarse sand for years and now am using it in the crevice gardens.  I've always found it to be a wonderful growing medium for plants that don't do well elsewhere in the garden.  Also, the stone that makes up the greater part of the crevice gardens seems to help retain the moisture and the plants there are the last to show signs of distress in this horrible summer of heat, drought and humidity that we have been enduring here.

Hello Paul,
I've checked the article by Ron Beeston on his work the making of the Crevice garden at Pershore with ZZ and a gang of helpers  in "the Alpine Gardener" number 301  Volume 73 number 3 of September 2005 but the dimensions are not given there. Ian is just chatting on the phone with Ron who says h is best estimate of the size ias around 25 feet by 40 feet .... hope  this helps!
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Paul Cumbleton on August 04, 2010, 02:05:38 PM
Thanks Maggi, very helpful  and for reminding me of the reference for the article.

The reason for asking is that I have made a proposal to my mangers that the centre-piece of our celebrations at Wisley next year for the centenary of the rock garden should be to build a new feature so that in doing so we also leave something for the future. I would like this to be a crevice garden. I have been asked to provide an idea of cost before any decision can be made as to whether this is something that could be funded. So I am trying to work out the possible cost per square metre. To do this I need to know how much rock it takes to build a square metre of crevice garden. I was told that the one at Pershore used 10 tonnes of rock (can anyone verify this?) but what I don't know is the area that this created. hence the request for dimensions.

If this project goes ahead  I may be looking for advice, never having built a crevice garden before! However, ZZs book is a great place to start and the other contributions to this forum also provide some insight.

Thanks again

Paul

You could do a lot worse Paul than consult dear Anne Spiegel (Astragalus) who has constructed an incredible cliff/boulder/crevice garden in New York State which is one of the finest private alpine gardens that I have visited.

Post by: Paul Cumbleton on August 06, 2010, 01:51:55 PM
Thanks everyone for their input, I really appreciate it. I have meanwhile become rather confused about sizes! For example, in ZZs book where he mentions the crevice garden at Montreal Botanic Garden, the caption under the picture on page 16 says this large crevice garden is 1.25 hectares (which is 12,500 square meters).Yet in the online article in the International Rock Gardener No. 4 (April 2010) it says this garden is just 150 square meters and used 60 tonnes of rock.. Or was this just for the part of the garden that was reconstructed? – it is not obvious.

Ron’s estimate of 25 by 40 feet for Pershore translates to about 92 square meters. Pershore say that they think the plan on page 10 of ZZs book is of the Pershore Garden (though it does not claim to be). But if so, that would work out about 50 square meters, barely more than half Ron’s estimate. I guess the only way to be sure is to do the 2 hour drive up to Pershore and measure it for myself!

If anyone out there who has built a crevice garden can give me a reliable figure for what weight of rock it took to build each square meter I would be very grateful. It would also be very useful to know what volume of compost it takes to fill the crevices per square meter. (I realise this will depend on the elevation, but if anyone has figures for their own constructions it would be most helpful.) If I can’t provide my managers with some possible costings that are at least roughly correct they won’t even consider my proposal to build a crevice garden at Wisley.

I take it you have not yet had a response from Pershore, then, Paul?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Diane Clement on August 06, 2010, 04:21:50 PM
Ron’s estimate of 25 by 40 feet for Pershore translates to about 92 square meters. Pershore say that they think the plan on page 10 of ZZs book is of the Pershore Garden (though it does not claim to be). But if so, that would work out about 50 square meters, barely more than half Ron’s estimate. I guess the only way to be sure is to do the 2 hour drive up to Pershore and measure it for myself!  Paul 

Paul, it might be a good idea to contact ZZ himself as he managed the building of the rock garden at Pershore and therefore would know the figures (he's not been on the forum for a while, so maybe travelling somewhere).  Another person who was involved with the project at Pershore was Alan Furness who has also built his own crevice garden so I am sure could give you some useful info.

Thanks everyone for their input, I really appreciate it. I have meanwhile become rather confused about sizes! For example, in ZZs book where he mentions the crevice garden at Montreal Botanic Garden, the caption under the picture on page 16 says this large crevice garden is 1.25 hectares (which is 12,500 square meters).Yet in the online article in the International Rock Gardener No. 4 (April 2010) it says this garden is just 150 square meters and used 60 tonnes of rock.. Or was this just for the part of the garden that was reconstructed? – it is not obvious.

Ron’s estimate of 25 by 40 feet for Pershore translates to about 92 square meters. Pershore say that they think the plan on page 10 of ZZs book is of the Pershore Garden (though it does not claim to be). But if so, that would work out about 50 square meters, barely more than half Ron’s estimate. I guess the only way to be sure is to do the 2 hour drive up to Pershore and measure it for myself!

If anyone out there who has built a crevice garden can give me a reliable figure for what weight of rock it took to build each square meter I would be very grateful. It would also be very useful to know what volume of compost it takes to fill the crevices per square meter. (I realise this will depend on the elevation, but if anyone has figures for their own constructions it would be most helpful.) If I can’t provide my managers with some possible costings that are at least roughly correct they won’t even consider my proposal to build a crevice garden at Wisley.

Dear Paul, I am really pleased to hear about idea of  crevice garden in Wisley. I have tried today to find out my stone consumption per square meter. One picture shows 1 m2 bordered with rope. Sorry I didn't take stones from crevices to have exact measurement, but I estimate it around 250 - 400 kg per m2. It fits to figures from Montreal (60 tons for 150 m2), 12 500 m2 is for sure the whole garden. Cunsumption is including smaller stones needed inside crevices, it is important not to underestimate it, as you need a lot of them.It is not enough to use just gravel, I hope that picture shows this little bit. As mediums I can highly recommend clean river sand. It supports so important roots development and as sterile material it also enables plants to establish after planting. Plus it is also very cheap material. In case of rain, you can also cover soil with sand and you can walk withou mud on you shoes. It also enables you to plant crevices even in case of rain, in case of time pressure. There is no problem with nutrition, as plant will root down through sand and quickly reach soil below crevice construction. I add some soil only for daphnes and dwarf conifers. Regarding roots temperature, this year we had around Prague 36 C degrees without any bigger problems for established plants. My experince is that wet sand in crevices is much cooler than air. It is because of no air circulation inside crevices, plus evaporating water cooles sand. Sand is able to abosrb huge amount of water and water has four times higher heat capacity then air. I can also mention watering savings, as there is much lower need to water, as crevices keep water inside for very long time and there is minimal space for evaporating.

Hi Jiri,
Thanks for taking the trouble to estimate your rock usage and for your other helpful suggestions. Today I actually visited Pershore to see and measure the crevice garden for myself. The total area (minus paths) is actually 28 square meters. As they used 10 tonnes of rock, this works out atabout  0.34 tonnes (340Kg) of rock per square meter. This fits in with your estimate Jiri and also with the Montreal example, which worked out at about 0.4 tonnes per square meter.

I still do not know if senior managers at Wisley will go ahead with my idea. Some of the things they have said recently make me think they are backing away from the idea a bit. I hope not. I hope to have a clear answer from them within a week or so.

The second crevice garden is finally finished.  The last part is only partially planted because this has really been the summer from hell.  Starting in the spring when we had record breaking days of heat, there has been nothing but that dreaded combination of heat (90s F), drought (2 months of no rain at all), and high humidity.  Many of the western american plants simply go dormant but revive when some rain comes, the high desert plants thrive although some really dislike the humidity, and many other alpines simply go permanently dormant.  Valeriana supina, thriving in the tufa garden at least 6 years, appears to be gone.   It's one of my favorites.  I'll do some planting in the new crevice garden in the fall and finish up in the spring.
Jiri's new crevice  garden looks wonderful.  The plants are really taking hold.  More pictures, please, Jiri.

Well done on your successful proposal, Paul.
I think you will find there is almost universal delight at the prospect: while there are some who are not much in favour of this style of growing there will surely be tremendous interest from visitors to the garden to see it there.
And to have ZZ himself involved.... a coup indeed  ;)

One of the places the pre-Nottingham Conference Tour will go is to Wisley.  Can't wait to see this crevice garden.  What  an amazing amount of work in just a few days.   I'm used to doing this work with one other person and no machines.  How I'd love to use those machines for even a day but I can see they're operating in a flat area, not on the side of a cliff.  Any machine here would probably land in the lower garden in no time.

Those of us lucky enough to be on the pre-conference tour got to spend the day at Wisley.  The garden was spectacular but first on my list was the crevice garden.  Paul et al have done an amazing job.  It's huge as the pictures will show.  The fun will be in the planting, because crevice gardens eat up plants.  We also got to go in the propagation house and see some of the plants that Paul is growing for the crevice garden.  It's a wide selection and I was happy to see some North American plants there as well.  I have to give Paul a "10".  He has accomplished so much in so short a time.  The pictures are:

Maggi, I sure hope it makes it to the show.  It's a wonderful plant - beautiful foliage and fabulous flowers.  Then again, some years a plant will just up and die almost overnight.  No particular reason - it's almost as if it woke up and realized that it was growing in the northeast and not the southwest.

I don't know how I have managed not too discover this remarkable thread for so long! Unfortunately in the far flung south-east rocks are not so easy to come by and I have concentrated more on building simple sand beds (they still grow plants really well!), but they lack some of the aesthetic appeal of crevice gardens, and definitely lack the romance of playing with rocks! We have had talks on the famous Czech alpine gardens and gardeners, and they must be the finest in the world notwithstanding some great gardens in the UK and US. Mine by comparison is relatively modest, though my interests are not, and a crevice garden now looms on the horizon!

Welcome, Tim, it is good to see you here.
 
I understand your local difficulty with finding a good rock supply..... here in Aberdeen, the 'Granite City', this is not a problem for us - grantie and sandstone are quite easy to source.... it 's down to the state of your back really, as to whether you can cope with the construction work!
I have been interested to see your posts on your sand bed " Fun with a Sand Bed" on the AGS site,
http://www.alpinegardensociety.net/discussion/inthegarden/Fun+with+a+Sand+Bed/531/  and I agree that this is a method that is much more accessible to folks than extensive rock work.

We have not made a pure sand bed in the body of the garden, as you have, but we have made sand beds, surrounded by vertical (part) slabs in a variation of  our outdoor sand plunges, and these are proving a popular home for many plants here in Aberdeen.... mostly bulbs, in this the home of the Ian the "Bulb Despot" ! You can see more of our crevice beds and sand beds in Ian's Bulb Logs.
http://www.srgc.org.uk/logs/index.php?log=bulb  is the main page and an index is there too.

 Also you will find quite a lot of discussion both here in this Forum and in the archived version of our previous Forum ( http://www.srgc.org.uk/cgi-bin/discus/discus.cgi ) where such methods of growing plants have been shown to be both successful and fun!

Tim, welcome to our forum. Have you ever seen the Utrecht Botanic Garden?

There they make amazing use of recycled building materials - old slates and roofing tiles, sewer pipes, paving slabs, etc - it may sound terrible but I was so inspired I came home and made up some troughs with slate, paving slabs and broken cement blocks.

After a few years it is difficult to tell that these are not made with stone.

I just nipped outside and took three of pictures of troughs : one using cement rocks, one with limestone marl and the other roofing slates. You can decide which if any you favour.

I really fancy making a crevice bed larger than a trough using a mixture of recycled materials- if only we had some space to put it.

Ian, I believe there are some quite large areas of the Highlands, as an example, where the population is sparse, and where you could put quite large acreage to good use. Of course you may have to protect from deer and perhaps the odd irate Gael.;D (I've just finished re-reading Arthur Ransome's "Great Northern?")

Ian, Harry Jans has shown us slides of the Utrecht garden and it is really thought provoking. I wonder how many people have taken up the ideas? I remember particularly the angled long shallow troughs, weird but clever. But the plants grow brilliantly. I think it shows the wonderful benefit of experimenting and trying different things. I must admit my real dream has always been a tufa cliff a la Harry and some of the growers in Germany, and of course Roy Elliott. Lacking that I have seen a picture somewhere in an AGS garden of a huge tufa boulder planted up and surrounded by other plantings - really enticing. It's wonderful when you find a way to grow a plant really happily.

Well that gives us all much to look forward to. Why not a sand bed on the Trump land? I seem to remember Peter Korn had something of the kind. Shouldn't be too difficult to divert a small stream to keep the sand moist. So al Fayed's been up to similar tricks? Wasn't Harrods enough? What greedy people they and their kind are.

May I add some pictures of a recycling wall like in Utrecht B.G. of [concrete] paving slabs.
Last Saturday we made a visit to a garden where such a wall was made and this wall is now almost 15 years old.
On the shady side there is a mix of Ramonda, Haberlea, Pleione limprichtii etc.
For those who are interested this garden is situated more than 4 m. under sea level!

Very successful planting area and pleasing to the eye as well as being a good use of recycled materials.
The Pleiones look especially good.

As a person living up a hill, though, the thought of being lower than sea level worries me ! :o

I constructed a new trough at the weekend and coincidentally this thread has recycled materials in it. I was going to post this next year just in case it didn't work but the opportunity has arisen so I will do it now.
Last Wednesday my wife and I visited the Explorers Garden in Pitlochry for the first time. We had a pleasant walk and the Meconopsis were coming to the fore. Another week or so and they would have been at their best. A lovely place and we will visit again. Met Julia.
More to the point - my wife MADE me buy some plants - mainly Lewisia's. So I had to find somewhere to put them. We had seen the Lewisia dry stone wall at Bodnant many years ago and I had tried to emulate it a couple of times. This time I decided to do something different. All my troughs are natural looking so I decided to do something a little more contemporary.
To the point.
Photo 1 - This was a Rhodohypoxis trough and I am aware that they are not necessarily hardy but they had flourished for for five years. This is the only one I found this week. Disappointing but an opportunity.
Photo 2 - This beam is wedged in the trough to ensure the front bricks don't settle in the compost.
Photo 3 - Layer 1. The bricks have small holes in them just at the height I needed them. The canes fit in the holes and are to ensure the next layer of bricks don't settle in the compost either. Roofing slates provide the back.
Photo 4 - Layer two in situ to see how everything fits.
Photo 5 - The first plant. The nurseries compost was washed from the roots and I then added my own mix and wrapped the root ball in thin card to ensure it stayed in place and allowed me to ease it through the holes in the bricks. The theory is it will eventually rot away.
Photo 6 - First one in place. All the plants had roots long enough to reach through the bricks and into the main compost area.
Photo 7 - Level one planted and ready for the top layer.
Photo 8 - Between the bricks I planted Sedum oreganum tenue
Photo 9 - Nearly done
Photo 10 - Completed.

Plant list - Lewisia cotyledon hybrids, Lewisia 'Little Plum', Dianthus 'Whatfield Magenta', Sempervivums 'Walcott's Variety and 'Fire Glint' Sedum spathulifolium 'Cape Blanco' and Purpureum, Sedum oreganum tenue.

I do hope this works. I will let you know how it gets on.

I must admit that my wife was unequivocal; "That's not very pretty ... don't you get any ideas!"
It reminds me of a ziggurat in a rainforest (but perhaps that's just the gin and tonic talking)!  ;D

You know, Graham, I think in a few months that brick surface will disappear as the plants spread. Then the effect will be of 'invisible'  tiers, I reckon. great fun.... love anything new like that!

Well that's the theory Maggi. I hope that they all settle in.
Cliff, we will see what your wife says when they have grown together and the Lewisia's are in flower next year. She wasn't seeing the bigger picture.
I have to admit to having to google Ziggurat, but you are right.

That wall of ramondas and asplenium is exquisite! It reminds me of an old retaining wall half way up Snowdon, next to some old mine buildings, which is full of ferns in variety. Unfortunately I only have a slide. One of our members has a great ability to discover recycled materials for free and has a large raised bed made with similar concrete kerbstones. He also (curse him) discovered a source of tufa(!) in an overgrown garden - some people have all the luck!

Congratulations Graham on your lateral thinking for your new contemporary trough; incorporating those bricks for your collection of Lewisias.  You've given me an idea for a small raised bed using these bricks in limited space.  Looking forward to seeing how yours develops with some photos.

Those Eriogonums are very moreish! (I use the word but can't find it in the dictionary). I haven't tried any yet in my sand bed but have previously grown them under similar conditions on a raised bed. The late Dr. Jack Elliott grew many species and stimulated us to grow more of them. At Wisley Paul Cumbleton has planted several on a raised sand bed near the alpine house and they make a great contrast to other plants. The smaller species are seen occasionally exhibited at AGS Shows but few people grow them. I shall look out for seed this autumn/winter.

Post by: astragalus on May 20, 2011, 02:28:14 PM
Cliff:  Somehow it seems strange to look at the garden without the crouching camerman in view!

Tim, the eriogonums are marvelous plants.  Look for seed of Eriogonum ovalifolium varieties.  Just plant them in full sun and once established, don't water.   During periods of drought when all gardeners are complaining and moaning, the westerners (eriogonums, penstemons, astragalus, oxytropis, trifolium etc)   behave like they're in seventh heaven.

Hi Anne,
I could say; "Anne Spiegel's garden is particularly moreish" or "I can't get enough green beans - they are moreish" or (as Maggi might say) "This chocolate bar is moreish, I could eat another seven"!

Definition : Something that leaves one wanting or desiring more ... and more!

I have always presumed that this common expression (here in the UK) would be in the American dictionary, but unless it refers to the Moors (Moorish), then it doesn't feature in my Mac's New Oxford American Dictionary.  I was gobsmacked!!!

In the crevice garden this morning.  Hopefully, the Onosma is setting seed and the unusual color will be reproduced in the seedlings.  Three self-sown seedlings have been found.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Lesley Cox on May 26, 2011, 11:44:13 PM
The Onosma definitely has that "full of seed" look to it that Boraginaceae get when they're going to reproduce. I'd be very hopeful in your position.

That Asperula is a real beauty. :P

Post by: astragalus on May 27, 2011, 12:59:25 AM
Not quite sure what the asperula is so I just call it "sp".  So many different things come from Asperula sintenisii seed.
The onosma seedlings I found were from last year and they look really healthy.  Maybe next year I'll transplant them and hope they duplicate the wonderful coral color the parent had this year.  It was truly different compared to others I've grown.

In the crevice garden today.  It's the start of convolvulus, moltkias, and acantholimons (not quite ready to photograph).  Everything is quite dry now but not too hot, and most of the plants seem to like life in the crevice garden.  I love it that the overall color schemes  keep changing.

Just starting now, the acantholimons. The one I used to grow as Acantholimon androsaceum had better color and shorter stems, but I'm told this is the same plant.
Maybe hindsight embellishes things like color but my pictures (slides) still show shorter stems.

The crevice garden is quieting down from the riotous colors of April and May.  Now there are some repeat blooms on daphnes etc and a few new things coming into bloom.  Then things will be relatively quiet until latter half of August when the zauschnerias will start making splashes of color I hope).

Thank you so much.  Right now everything is sweltering in the heat, but the eriogonums are relishing it.  Their foliage looks fresh and very tight.  In their native habitat, 20% humidity would be considered a sauna and here the humidity is 90%.  It's amazing the adjustments many plants can make, isn't it?

Also growing on top of the cliff now is Dianthus arpadianus.  It bloomed heavily and was never deadheaded.  Now I find that some of the stems appear to be making new little dianthus cushions at the top of the stems.  Has anyone ever seen this happen?  It's new to me.  What does one do with them?  Could I pin the stem down and try layering?  Sorry for the quality of the p[icture.  Have been having a little difficulty lately with the camera and taking good close-ups 
Also a picture Of Onosma nanum in the regular crevice garden.  It seems to be a happy plant.

The crevice garden looks amazing, Anne.  If viewers could only understand a modicum of the effort required to get those cliff top boulders clear of bramble and weeds to allow such precise and immaculate planting. 
I would be tempted to peg down a couple of those stems but let the rest develop normally over winter and hope that they grow foliage down the stem forming individual buns over the cushion?
Greetings from an unusually warm Lancashire.  Hope dear Joe is well.

Cliff cannot speak highly enough about Anne's garden and I must say that every photo I have seen confirms to me that he is quite right to be so full of praise for it. It is a wonderful place, a real tribute to Anne's eye for detail and sheer hard work... and I always feel for her tribulations against the 'antlered rats'.

Yes, there is natural stone, yes the site is beautiful but human hands and heart have made it the glorious garden it has become and which we are fortunate to be able to share , if only by photographs.
An inspirational garden, in my opinion.

Thanks, Cliff.  Joe is fine and staying away from garden "projects" although he did help with leaves yesterday.

Lesley, it's wasn't just brambles, those thorny darlings, but also miles of poison ivy, which I find far worse.  If it were not for the miserable itchy rash it produces, poison ivy would be the world's best ornamental plant - able to withstand any type of soil (not happy in the sand beds), can take any kind of weather, has lovely polished foliage with excellent fall color,  can grow as a vine, ground cover or even shrub, the antlered rats don't touch it - AND - it's almost impossible to kill.

There IS something you can do in the crevice garden in the winter (not technically here yet but might as well be).
You can start preparing for daily forays by hungry deer.  The chickenwire goes up to the top of the cliff, and various rocks are placed to keep the wire from sagging on the plants.  Deer are very fussy about where they place their feet.  It may not look pretty but it's effective and has really become necessary.

Another new crevice garden that I've been working on since September with a break due to an unexpected October snowstorm.
This one is at the north end of the cliff and was nicknamed years ago "The Last Outcrop", because I promised I wouldn't develop the garden beyond that point.  I  made no promises about the other end and have been developing that for the last ten years with many raised beds and crevice gardens.  In the meantime, "The Last Outcrop" became a jungle of brambles, poison ivy, saplings and more poison ivy.  The first picture shows it in October covered by snow.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on November 22, 2011, 04:20:20 AM
The crevices of "The Last Outcrop" are all sizes and mostly deep.  All the junk is coming out and when I have an empty crevice I pour in wood chips that have been put through a chipper a second time to speed up decomposition.  Most of them are half rotted already since they have been sitting for four years.  I'm trying to get it all in before snow comes and stays but it's a big area and it may not happen.  But at least half of it will be ready to sit out the winter and settle.  It's fairly open north with an apple tree and a hop hornbeam to give some extra shade.  It will be space for very different plants.  It's been a lot of fun and a few backaches but I can't wait for spring to start some planting.  A case of poison ivy in November, however, is not fun.

Anne, you make me feel such a wimp that I'm complaining about over-the-road's cats padding about, now that Teddy is no longer with us. One had left a shallow indentation on many seed pots overnight and one sat in MY driveway and watched me from just a few metres away as I raked up strimmed grass today. I heaved a clod at it but it just sat there as if it had a right to.

Great news though for me, first seed up of Primula wollastonii (sown 9th June) and the first of Wim's Pinguicula grandiflora seed also. Result of several days of persistent rain I expect.

I can IMAGINE the effort needed to clear the last outcrop... and that's without any knowledge of how tricky it must be to work with the poison ivy... my admiration for your work is tremendous..... but it is no less for the yearly effort you have to put in to spread the chicken wire to try to ward of the antlered rats!

No-one could ever call you lazy, Anne, that's for sure!   :D

Maggi, right now the garden is reasonably deer-proof.  It's hunting season and they temporarily change their trails after our hunter (comes every year and bags his limit on our limited acreage!) kills a few of them.  But then they come back after the season with a vengeance having picked up some of their cousins to swell the herd.  That's when primal scream comes into play and I pray every day for very deep snow to help protect the plants.

Cliff, I didn't know if you'd remember The Last Outcrop.  They are large rocks but the weeds etc were so high they were difficult to see.  The hardest part has been hacking out the trunks and roots of trres that seeded themselves into the crevices.  Joe is bringing up chips from the long piles beyond the water garden and has been quite dismayed at the speed with which I use them up and say "more, please".  In the spring I'll dig pockets and fill with my mix and plant.  The winter should help settle everything and I'm also tramping the crevices down almost daily to really pack the rotted chips down.  Think hellebores, epimediums, hepaticas, jeffersonias and ramondas.  It may be too dry for many primulas, too bad.  Can't wait to plant.

Wow now that is what I would call big rocks very nice.   We have problems this year with moss growing in the crevices despite the planting material being 75% sharp sand, never seen so much rain have had twice our annual rainfall over 4 ft (250cm) and yes it is still raining. We well remember last year when everything was buried in snow not sure which is best, cheers Ian the Christie kind.
We have had an incredibly wet year here as well.  It's nice not to hear the voices of doom all the time about the reservoirs being too low.  All the rocks of The Last Outcrop are covered with moss and lichens.  Some of that should disappear with the clearing and more light and air as a result.  I tried to save the little ferns I found - mainly ebony spleenwort and the little polypody ferns that populate the north face of the cliff.

Lesley, too bad about the cats.  I've had trouble before with cats - mainly using the sand beds as giant litter boxes.  However, they made up for it with avid mousing and chipmunking.  Never had a problem with those critters when we had the cats.  Ranger, our dog, does not allow the presence of cats in his territory, or anywhere else if he can do anything about it.

I often think it would be great to see a time lapse photography of a garden in progress! Some of us would certainly look like tortoises by comparison with Anne and Peter Korn in Sweden! It must be wonderful to work with the landscape in this way - it reminds me of Dilys Davies, past President of the Hardy Plant Society, who talked on her garden in the Lake District and a cliff face which she abseiled down to plant. This is real gardening and so exciting to see.

Hi Anne,
we don't have deer or bears to worry about here, but the echidna has been running rampant and digging up parts of the rock garden. He (Erroll) -or is it she (Edna)?- is quite capable of pulling apart some of the rockwork, though your "Last outcrop" may be big enough to defeat them!  Unfortunately ants seem to love making nests in the rock garden and echidnas love ants!

Fermi, every eden has its serpent, right?  I've always had trouble with a kind of wasp in the sand beds.  They are incredibly efficient tunnelers.  They dig deep holes to bury their food supply and they do their digging right next to my plants that they use as markers.  They can sever roots quite neatly and then the plant just collapses overnight.  They come back every year, I fill their holes and place flat rocks here and there to discourage them but they're quite fixated that this is the only place to dig.

Ann, I have these sand tunneling wasps as well.  They seems attracted to open sand, so maybe the deterrant is to cover sand beds with pebble stone or gravel.

I held back from going ahead with ordering any because, as usual, I have to many projects on the go. But I never forget a wonderful tufa garden Alan Furness was constructing at the time of the 2001 Conference at Edinburgh, and wished I could just pick it up and put it in the back of the car!!

Hello,

This is my little, brand new crevice rock garden. Now it is only planted with some Saxifraga plants and Primula auricula hybrids, but I intend to plant it with many other species, mostly cushion forming species. Like Androsace, Draba, Dionysia, Arenaria and Acantholimon. Androsace and especially Dionysia I will try in the spot where there is a roof overhang. In this spot, direction East, hardly any rain will fall on the plants.

This is really a 'crevice garden' but you hardly see it, because I applied many little, marble stones and marble stone chippings to mask the crevices. The other rocks are some granite side-wall rocks, mainly slate side-walls and there are also some bigger marble (limestone) rocks which you see in the higher outcrop and in front.

The growing medium is one third limey soil and two thirds mixed chippings 2/16 mm (gravel 6/10 mm, grit 2/8 mm, lava 2/8 mm and limestone 8/16 mm).

I decided to make this little crevice garden, being inspired by the great crevice garden builders, like ZZ.

Hi,

Here you will see two pictures of my sandstone rock garden, not really constructed for the crevices, but more to drill holes to plant mainly Saxifragas. It measures only a bit more than 1 square meter (120 cm - 130 cm), but it is 80 cm high, because most rocks stand upright. But it does have a lot of crevices too. It is unbelievable how many alpine plants can find a home in such a restricted space. I have made it last summer, so it has still a lot of 'growing potential'. :D

Sure Tim ,it was my friend Harry who inspired me .....Not alone on making a vertical tufa garden but in generally ....on gardening with tufa !
For me ,the vertical tufa garden has one big problem. And that problem is that it becomes dry much easier . Tufarocks who lies on the ground have the advantage from capillary activity .But the vertical rocks are free and this means they dry out easy.
So this mean that such vertical tufagarden needs much more watering .Also because of that I started to fill up the space on the back with sand .But even then I need to water it on very regulary basic. The horizontal tufagarden needs much less care .
So my advice is to think about watering before building.

Hi Lesley,

But a rock garden is too heavy to be stolen by thieves, and a car is sometimes so easy to be stolen ...
So, everything has its advantages and its disadvantages.

Hello Lesley,

Yes indeed, it's me in the picture, starting to look at that big world we live in.

Ha, de Luc,

This kind of sandstone is very porous, but some pieces have a harder structure than others. It also has a lot of nutrients, if you break a stone you will find old sharkteeth and a lot of fossiles like shells. This sandstone was formed in the Ecoceen period, so very old indeed.
The Saxifragas I have planted in them seem to respond well.

You don't always need tufa to grow plants in. I even have drilled holes in the rocks of my big rock garden, and these rocks are very hard, they are marble rocks.
I will enclose a picture of Saxifraga Winifred, growing inside a marble rock. 8)

http://www.geo.ucalgary.ca/~macrae/timescale/time_scale.gif
Your plantings look very nice!  Thanks for showing us.  The presence of shells and other marine fossils in the sandstone suggest that it is pretty calcareous, likely calcite-cemented, so it likely provides similar conditions to tufa, though less porosity.

 ;D That depends on your definition of young and old and your reference points....if you look at how long humans populate this earth, rocks from the Eocene are very old, if you look at the age of the Earth, not that much...but I guess the last point of reference would be the best when speaking about rock, so than I have to agree with you, Lori, not that old at all!

Post by: Leiomerus on February 01, 2012, 03:38:30 PM
Hi Lori,

When I was 18, someone of 40 years old, was in my opinion 'old', now I'm 44 and I don't think I'm old, but young,  ha ha. ;D
Interesting time scale you mentioned there, so the 'Eocene' is about 35 - 55 million years old. Thank you, I learn everyday.
About the composition of the sandstone : I looked it up : calcareous sandstone, made of fine quartsparticles, calcareous fossils, glauconite granules and it's calcite-cemented indeed . So you made a good guess. In my region they made a lot of churches with this sandstone from 'Balegem'. I only make rock gardens with it. ;)

I've been trying to post pictures and keep getting "file too big", despite the pictures having been downsized per usual.  The garden is at least 4 weeks ahead because of the crazily warm temperature.  Things are starting to bloom although we now are getting deep frosts every night.  Phlox 'Betty' is one of Dick Redfield's microphloxes.  This one was named after his sister and is in the upper crevice garden.

I like that little phlox, don't know microphloxes at all! I need to read the new book on the genus which has been so highly recommended. I haven't yet developed a crevice garden but hope to attend the Czech Rock Garden Conference next year and see the gardens made there. I would love to learn how to succeed better with some of the dwarf legumes, so various different growing conditions should be on the cards!

The Phlox 'Betty' is quite different from what I have as 'Betty,' a subulata form. It is soft pink with a scarlet centre and is my favourite subulata, but surprisingly difficult to sell.

Post by: astragalus on April 01, 2012, 11:16:48 PM
Lesley, I think my Phlox 'Betty' is the real thing because it came from Dick Redfield.  Maybe there's another phlox called Betty?  Another microphlox of Dick's is P.'Herbert' named after his brother.  They stay quite tiny in bloom.
The second picture I posted was of course  Androsace carnea in the crevice garden.

Tim, the best way to grow the wonderful peas is to wring the moisture out of your climate.  If I can get them through the spring they tend to do OK because we can have long periods here of heat and drought.  They revel in that but I'll never get them to look the way Utah and Colorado growers can.

Post by: astragalus on April 18, 2012, 02:13:23 PM
Everything in the garden is almost a month ahead in bloom and the crevice gardens have started to bloom.  The last picture shows the back side of the cliff with some of the microphlox in bloom in natural crevices.  Almost everything that has been planted in these natural crevices (some 40 plants), has come through our snowless winter with only three losses so far.  I know this is a really nice group so I thank you in advance for not laughing at the picture of Eritrichium howardii with two blooms.  As of yesterday the count had doubled with many more buds to open.  This really is my favorite area of the garden.

Anne, I love your turn of phrase - "wring the moisture out of your climate." It says so much about needed conditions and is great creative writing as well.

And of course I love the plants in their habitat. That must be the nearest to a real mountain scree that could be found in a garden. You are so fortunate to have this.

Tim, must the pea seeds be chipped? Would an overnight soak in (starting as) hot water not soften the coats enough to let germination start?

Luc, the reason it looks so realistic is because it's real.  I just cleaned out the natural crevices and put in rock chocks where needed to prevent the plants from sliding downhill every rain storm.  It takes time for the roots to get anchored.  I'd love to take the credit but I can't.  The flat crevice work is mine.
Tim, Astragalus utahensis and Oxytropis are not only lovely peas, but they are among the easier ones and have a good life span in the garden if the weather cooperates reasonably.  It seems to be difficult to get them to form viable seeds or even pods in my climate.  That's where Alan Bradshaw's "Alplains Seed Catalog" comes to the rescue.  His seeds germ inate very well and he has plants no one else seems to have.

Work is continuing on "The Last Outcrop".  I'm busy making soil with half-rotted chips as a component.  Adding top soil (fairly neutral) and some sand rounds it out.  A slow-release fertilizer is added at planting.  So far, I've planted epimediums, hellebores (including "ivory prince" and "pepperminy ice" - this last is one of Marietta O'Byrnes hybrids), haberleas, dodecatheons, anemonopsis, hepaticas etc.  There will be another round of soil mixing, grading . firming and planting tomorrow.  Most of the plants have just been dug up from elsewhere in the garden with the exception of two named hellebores.  The chips sat all winter and since there was no snow cover I was able to trample them down daily.  I'm trying to remember to take pictures and have a record, something I usually forget to do.

Finally, my latest project on the backside of the cliff beyond the highest crevice garden.  It's nice to have at least two projects going at once.  If you hit a problem with one and can't see a solution, you go to the other work site and after a few days or so a solution usually presents itself.  It saves days of frustration and of course, in the meantime you're getting a lot done.  This crevice project is using the rocks I couldn't move.  I keep putting mix in and as each rock is set, it usually tells you which one to use next or which one you need to play with with a chisel and rock hammer.  This last can be fun and leaves you with a lot of smaller pieces to use in various ways.  These crevices will be a combination of large and small, and will slope downward to follow the slant of the cliff back.

Anne - I was going to say looking at these pictures that your garden almost makes itself! But of course that is completely untrue. It must be marvellous though to have those natural rock outcrops leading the way and I love the crevice bed in the foreground of the last photo. One of the most well known gardeners in the UK is Dily's Davies, of Allium fame, and she had a garden in the Lake District with a cliff face which she abseiled down to plant! Really gives gardening some excitement.

Tim, it's challenging but fun to work on large rock projects.  I enjoy shaping some rocks but really prefer the challenge of finding the perfect piece for a particular spot.  The crevice garden to which you referred is the upper half of the last one built.  For some reason all the Daphne x hendersonii 'Ernst Hauser' didn't make it through our non-winter although they were fine elsewhere in the garden.  But most of the plants are doing really well.  There is really a third project which is the ongoing cleaning out of the natural crevices on the backside of the cliff.  That's only about 1/4 done and I'm beginning to wonder if it will be finished in my lifetime! (LOL)  And that's where I'm heading now to get some more done.  They predict rain the next few days and that's not the time to be on sloped rock surfaces.

Cohan, the rock seems to have added benefits which make the difficulties of working with it worthwhile.  I find that I can carry plants through droughts better when they are planted in deep rock crevices rather than the open garden.  Petrocallis pyrenaica, which already has finished blooming, has grown for years in a knife thin crevice.  I cleaned it out to the depth of a large carving knife borrowed from the kitchen.  That was as far as I could reach and I hadn't found the bottom.  Yet it died in the rock garden proper in a long drought period.  The rock seems to keep roots cool and moist and also protects them in the winter.  I've yet to see anything heaved out of a crevice - not so in the rock garden this winter with all the thaw and freeze cycles we had.

Most people need trucks to bring loads and loads of rock to their home, trucks full of sand, little chippings, common soil to make a heap. Mostly you need a bulldozer. I costs a lot of money, work and time to make something which looks a bit like the real thing.
And some people are lucky and smarter and simply buy a place with a natural rock garden, but with still a lot of beautiful work .... ;)

The lower crevice garden during the time of genistas and one of my favorite times.  They have an affinity for stone and make waterfalls of yellow.  Genista depressa will hug the contours and is wonderfully floriferous.

Growing in a crevice is a good way to keep a plant in check.  Asarina procumbens is welcomed in this dry garden.  I'm aware it is considered a bit of a thug in moist gardens, but it's really lovely.
Also, great excitement because Erinacea pungens has finally bloomed after a wait of some years.  Always a celebration when a new pea flowers.

Post by: astragalus on May 02, 2012, 11:27:54 AM
Lesley, the erinaceas have been in the garden for a few years not doing much of anything.  Having seen it in bloom in someone's garden once was enough to
keep me patient.  It was so exciting to see buds this year on one plant.  Where do you grow it?  Soil type etc?  I have it in full sun in a fairly lean, fast-draining mix.  Perhaps this is not optimal?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Tim Ingram on May 02, 2012, 04:22:33 PM
I think it must take a time to get into flowering mode. I have had a plant for four years or so and this year it is flowering for the first time - I hope it will go from better to better. The best plant I have ever seen was in a ground level raised bed inside a long dutch light greenhouse at the Malahide Garden in Dublin - you could hardly see the plant for flowers! Summer heat and dryness probably helps.

Post by: Lesley Cox on May 02, 2012, 10:40:30 PM
I have two very large plants now and they are both in hot, full sun troughs which are never watered except by rain. One is of limestone though the mix was not made limey and the other is hypertufa, both exceptionally well drained. In fact, the limestone trough broke in half corner to opp corner when we moved here and was put together again just by binding heavy wire round it and there's a gap of about a cm from top to bottom, right across, so no moisture is able to accumulate.

I think it was about 10 years before the first one flowered and perhaps 5 or 6 for the second. Both flower very well each year and if I can bring myself to suffer the pain, give good seed. It has to be collected very carefully and I use a pair of long-handled tweezer things, such as my doc uses to remove splinters of glass from a foot. The seed germinates reliably and quite quickly.

Talking of which, from a March sowing of Holubec's Anarthrophyllum desideratum, I have, so far, one seedling up, about a month ago. Its first true leaf is a sharp spine, so true to its common name!

Thanks so much for the Erinacea pungens information, it's very helpful.  Lucky you to have an anarthrophyllum seedling.  All the peas I saw in Patagonia were fabulous and I'd be thrilled to be growing any one of them.  Good luck with your seedling and may there be more soon.

Maggi and Luc, so far it's growing larger and blooming better each year and I'm just trusting that that means it wants what I'm giving it - lean, fast-draining scree and full sun.  But before it decides to leave the garden permanently, it would be nice to know what it is so I can look for seed.  So far it has flowered each year but made no pods.  Maybe this year?

I have been intrigued by Anne's lovely Astragalus, which I thought was an American species and have been  wondering where I have seen something like it.
Anne, might it be a Turkish species? Mojmir Pavelka has shown a little furry yellow species which he calls Astragalus pelliger... though I think that is not a fully accepted name... have a look at this plant from Dedegol Dag in  the IRG  #23 - page 7......
http://www.srgc.org.uk/logs/logdir/2011Nov241322170676IRG_23_-_November2011_.pdf (http://www.srgc.org.uk/logs/logdir/2011Nov241322170676IRG_23_-_November2011_.pdf)  8)

Astragalus pelliger (as in the IRG) is very nice and one wouldn't say "no" given the opportunity but I think Anne's is ever better, so furry, so silver, so compact. 8)

Anne, Astragalus lutosus foliage looks very similar to your plant.
http://gilliamcountygarden.blogspot.com/2011/08/astragalus-lutosus-in-garfield-county_05.html (http://gilliamcountygarden.blogspot.com/2011/08/astragalus-lutosus-in-garfield-county_05.html)

The flowers and calyxes on A. lutosus aren't furry as in the yellow flowered plant you show.
Here's your plant of A. lutosus on the NARGS wiki.
http://nargs.org/nargswiki/tiki-browse_image.php?imageId=3115 (http://nargs.org/nargswiki/tiki-browse_image.php?imageId=3115)

Of course, a critical part of the ID will be the characteristics of the pods.
http://www.alplains.com/images/AstragLutos.jpg (http://www.alplains.com/images/AstragLutos.jpg)

Its dwarf, hairy, and yellow flowered, but the beautiful A. yunnanensis has a different overall look about it.
http://www.jansalpines.com/gallery/main.php?g2_itemId=14788&g2_imageViewsIndex=1 (http://www.jansalpines.com/gallery/main.php?g2_itemId=14788&g2_imageViewsIndex=1)

The Flora of China summarizes the size and distribution of the genus, finding an ID will not be easy!
About 3,000 species: ca. 2,500 species in the Old World, represented in nearly all parts of the N Hemisphere, ca. 500 species in the New World; 401 species (221 endemic) in 59 sections (two endemic) in China.

You HAVE been busy Mark. The white-flowered lutosus is amazing. This, if I read rightly is Anne's own picture/plant? What incredible plants these pictured species are. So very beautiful. 8)

The pictures of lutosus in the wild, if I didn't know better I would say were our own Swainsona novae-zelandiae (I think it's called something else now) but its flowers are brownish or in the best forms, pink. Very rare nowadays too.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 10, 2012, 01:48:10 AM
Mark, it is most definitely not Astragalus lutosus.  Since it hasn't produced any pods yet, which is often most critical to pea identification, I'm still at a loss.  Attached are two close-ups taken today by Jim Almond, who is currently a house guest.  The foliage appears to be much tighter than the Turkish astragalus although there are certain similarities.

Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 11, 2012, 04:28:48 AM
Maggi, Mark et al -  One of the most distinctive characteristics of my mystery astragalus is the very inflated and furry calyx.  This is definitely not a characteristic of A. lutosus or A. yunnanensis.  I've grown A. lutosus - it is nothing like the mystery astragalus.  Astragalus pelliger carries its flowers in a  tight head.  The mystery astragalus absolutely does not.  This is not a characteristic that's apt to change depending on where it's grown any more than the pods will change.  If you look at the pictures attached I've tried to show both the calyxes and the habit of growth.  The foliage is quite tight, not sprawling.  The banner petals are the largest part of the flower (apart from the calyx) and the "wings" are tiny, just large enough to cover the keel.
Thank you everyone for your interest and information.  The list of "what it is not" is growing longer and longer.  I'm hoping it will set pods this year since it's blooming so beautifully.  It makes me very nervous to have only one plant.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: TheOnionMan on May 11, 2012, 04:57:52 AM
Anne, good closeup photos for further diagnostics.  In my previous message, it was only the foliage that seemed close to A. lutosus, but clearly the flowers are very different; I was not suggesting that either lutosus or yunnanensis were an ID for your plant, just interesting diversions along the way of searching for an ID. The last item I posted, demonstrating the immensity of the genus as cited in Flora of China, indicates that finding an ID, without provenance of the plant's source, will be quite the challenge indeed, analagous to finding a needle in a haystack.  Regardless, it's a wonderful plant, even without a known name.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Maggi Young on May 11, 2012, 10:58:35 AM

The great thing is I am discovering a whole lot of other wonderful species (ref. Mark's message) along the way! Would it be worth trying to hand pollinate Anne? I know most peas are self-fertile but this one looks as though it either needs another clone or a helping hand.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Lesley Cox on May 12, 2012, 11:45:38 PM
The calyces are as decorative as the flowers and the leaves themselves make the plant very fine, even if it had no flowers at all. I hope a name can be found. Was it from seed Anne from someone like Alplains?

I think we need a thread specifically for peas (Fabaceae) or do we already have one? (I fine the new Index a bit daunting. Scrub this. I must say that having followed a Forumist's tip and clicked Forum, I have no problem at all with the Index. Everything as before.

Post by: astragalus on May 13, 2012, 01:50:28 PM
Lesley, I'm fairly certain that it wasn't from seed because I only have one.  Usually I'd come across a label without plant saying "Astragalus sp", meaning the seedling died without my noticing.  I simply don't recall so I'm assuming it was a nameless gift from a nurseryman who dabbles in peas and knows that I love them.  Right now it has 14 flowers and is indeed sensational.

Tim, the mystery astragalus is trying to set seed right now.  Unfortunately, we are in the middle of unseasonable heat and "mugs".  This is usually death for the seeds forming.  I opened one pod and it was empty and I looked at another and could see the condensation inside the pod, not good.  I'm just assuming this is a drylander since so many of the astragali are.

I agree totally, Maggi.  Today we took the cable car out of Arabba to Porta Vescova with seven guests and saw Eritrichium nanum, Ranunculus glacialis, Linaria alpina, Androsace alpina, Geum reptans, Gentiana verna, Gentiana acaulis, Senecios, Geum montana, Soldanella minima and alpina, Arenarias, Pedicularis, Thlaspi, Veronicas, Semps and Sax's in profusion.  The sun shone dutifully for the fifteenth day on the run (just two thunderstorms at night) and life is as sweet as it can get.
Yesterday we took the chairlift out of Pedraces and saw meadows of indescribable beauty - swathes of Ragged Robin turning the hillside pink, Arnica everywhere, orchids by the hundreds of thousands (no exaggeration) and kaleidoscopes of colour at every turn.

Back home from my "other" home, the Dolomites.  Cliff and Sue were there at the same 5time and we managed a hiking day together.
It was a vacation of wonderful plants, people and weather.  We were hailed on one time coming down on a lift - an adventure to be sitting on an open lift clutching backpack and poles while being stung by ice pellets.  Photographed marvelous crevice plants and hope it gives some ideas.  Surely the Calamintha alppina would be incredibly easy to try. (Maybe it's now Acinos alpinus?)

Maggi, since we came home to horrible heat and humidity, I'm staying out of the garden.  Many things have gone dormant, hopefully not permanently, the crevice gardens are doing well and for some reason the daphnes are starting to rebloom.  Everything is extremely dry and the westerners are loving it.
Here are a few more crevice plants from the Dolomites

Such wonderful pictures Anne. Surely the best we've seen on the Forum of Eritrichium nanum and I was thrilled to see the Paedorota which I grew from seed once and had doing well until a very hot, dry summer killed it. It's a lovely thing and one day I hope to have it again.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on July 19, 2012, 03:40:52 PM
Thanks so much, Lesley.  The kudos go to Joe who does most of the photography.  Paederota bonorata does very well here in the garden and seems to be able to go dormant (usually) during periods of drought.  I've thought several times that I lost it and back it came with autumn moisture and lower temps.  It's asking a lot of alpine plants that can have an icy bath at almost any time of the year to adjust to lowland gardens with heat and humidity.  You have to love the ones that make the effort instead of immediately turing up their toes.  Have you tried Calamintha alpina (Acinos alpina?)?  It's been very successful here and will seed itself.  For some reason I haven't had great success in moving it except at seedling stage.  It has a very long bloom period as well.

Hello everybody, I have been very busy this summer if fact I seem to have missed the summer however I have done some new raised beds in my garden, you may well ask do I need more garden to look after well some plants have grown bigger and needed moving and I have many new and exciting plants to find room for thanks to my friend Cyril. I have made a crevice garden at the south end of the island with a Lage Azalea in the middle along with a pink viburnum and other Rhodos to provide some shade for the north end of the island. I was very lucky to be offered some large Swedish peat blocks from our friend Bob Potterton who was speaking in Sweden, I picked these up at Lamberton last week so now what to build. I took my chain saw and cut the blocks (they are very dry and hard)into three pieces long ways this was just what I wanted to build a crevice with peat blocks the dust and loose peat was blown everywhere this pleased my wife no end as it got into everything.  I filled up the peat crevices with a compost mix one third John Inness two thirds peat added a little fertilised as I went, not sure if this may be wet in winter will have to wait and see. I have planted a backbone of small Azaleas and Rhodos with gentians soldanellas trilliums petiolarid primulas will add mpore in spring. I also placed two tree roots amidst this structure just to add some interest and planted some Cypripedium division from another garden. I am posting several pictures and will let you know how it goes I realis that the peat blocks will take a long time to get wet through but I hope by then that the plants will grow into them.  cheers Ian the Christie kind.

Ian - its just struck me that you need several gardens in different parts of the country to grow all the plants you want to grow! The peat bed looks great, and just the thing when we cut down an old conifer hedge on the shady side of the garden to give a new planting area - what chance of growing petiolarid primulas and shortias(?); David Sampson used to grow these very well. I might be better off visiting Scotland!

Tim yes it would be great to have several gardens but it would take all my spare time (do not have any) but you are also welcome to visit.

This is my new, small crevice garden, but nevertheless composed of a lot of stone. It is mainly a slope towards the south east, because I want the plants to profit from as much sunshine as possible. It is built next to my house, so it gets shade from noon till the sun gets up next morning. This is a very good place for Saxifrages and some little plants have already found a home in this crevice garden. 8)

Post by: Leiomerus on October 23, 2012, 07:03:28 PM
Thanks for your apprecitation !

This crevice garden is made with different stones, which came from an old rock garden that I dismantled . Some stones are a bit flat, others are little rocks with various shapes and even cobblestones were used. I don't know if 'cobblestone' is the right word, I mean stones that were used to build roads.
I also took some rocks and a big hammer and I smashed the rocks into smaller pieces. These small pieces were used for topdressing. I wanted  the whole thing to look a bit like a scree.

I will surely post some pictures when the plants get bigger. I'm sure they love this spot, not only for being surrounded by rocks, but also because there is always a lot of wind here, next to the house, since I live in the country with a lot of open land. :D
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Leiomerus on December 04, 2012, 08:51:22 PM
I have changed my new crevice garden a little bit. Now I have the disposal at some new stones, I replaced the rocks of which I thought they didn't fit, with better ones, so that the overall colour would be better.
The pictures taken, are of the rock garden in a wet condition, so you see very well the different colours of the stones.
I also added a new, lower construction next to the stairs. This I couldn't do the last time, because of some 'irrigation work' I had to do.

This slope is mainly planted with little plants of Saxifrages, the plants I love the most. ;D

Post by: Lesley Cox on December 04, 2012, 09:17:40 PM
What a wonderfully natural home for saxifrages and the like. They will surely love the rocky places with tiny crevices and perfect drainage. And all this frim such a very young Forumist too. ;D

I have thought of getting a truckload of mixed size scree-like material and simply dumping it, planting where the material falls. Wonder how that would work?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Leiomerus on December 04, 2012, 10:02:49 PM
Thanks Lesley.
I don't think your idea would really work, it would be a nice scree, but the plants would not survive. They don't need much, but still they do need a little bit of growing medium like a good draining soil.  ;)

Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Lesley Cox on December 04, 2012, 10:18:38 PM
You are probably right Leiomurus. I seem to remember a few years back a Norwegian Forumist (can't remember his name and we haven't heard from him for some time) had done just that very successfully but he'd had the material tipped at the top of a slope and much of it fell down, in a natural way. When the plants were inserted I expect they rooted though the scree which wouldn't have been too thick, to the soil underneath. I'm sure Primula bella was growing and flowering nicely.

You're right as always Maggi and thanks for the link. It gives an excellent idea of what plants are suitable for such places. Geir is a really good grower though, which helps.

As a matter of fact I remembered his name at lunchtime as I stood in a supermarket queue though I can't imagine what brought it to mind. I said the name out loud and got some very old-fashioned looks from those in front of me. Used to that nowadays.

David, your nice Dianthus is very like one which appeared here in a batch of seedlings from D. a. 'Joan's Blood.' All were true except one which was taller and a little smaller in flower and I think must have been pollinated by the nearby D. deltoides 'Steriker.' It is proving to be a very good plant with the same dark reddish green foliage and flowers of a hot magenta, going on for ages but has set no seeds. I'm doing cuttings from it.

Post by: Tim Ingram on December 05, 2012, 10:49:50 AM
The great thing about plants is that they can tolerate a remarkable range of conditions. Some friends made a very crude scree using broken bricks and anything else available (sounds a bit like one of the constructions that Farrer railed against), but then filling in with sand and woodashes etc. A lot of plants have established in it, but not anything really choice. There is a great Volume of the AGS Bulletin (no. 2, 1933) almost totally devoted to screes with some pictures of the Botanics at Edinburgh and Branklyn in Perthshire, which both had amazing plants growing in them. Alan Furness' garden (simplistically) is almost like Lesley's description of piling a whole variety of different sized stones and rocks all together but done with great panache and skill - and can there be a better alpine garden in the UK? And then Robin and Sue White have simply planted in 4 or 5 inches of gravel over the soil (see an entry I have made on the AGS website). Alpine gardening is so much easier than people think, ha ha! Beyond that though it does become a real art form, which the crevice gardens can show, a little like the early days of the AGS when using rocks was as important as (or more than) the plants. Jiri's pictures of crevice gardens show that rather beautifully. (I should say I have a long way to go to emulate any of this!).

Post by: astragalus on December 05, 2012, 01:16:16 PM
Lesley, I don't think your idea is far off the mark at all.  I'd just add another step.  After you dump your mixed rock, throw shovels of mixed sharp sand and soil over everything and let the rains wash it down.  If you're in a really dry area you would have to use a hard spray from a hose to make rain.  You could do it in stages until you reached the consistency you want.  I think it could work well and it would certainly be simple.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Maggi Young on December 05, 2012, 01:44:19 PM
I'd go a stage further than Anne and lay down a good layer/mound of sand before the rocks, as well as over the top to wash down.
If the underlying ground is well drained I think this could work well. 
Title: Re: Crevice Gardening ......in defence of rock.....

Not sure where this picture belongs.  It's part 1 of garden protection for the winter - marking the garden edges to keep the demolition guy (excuse me, I mean the snow plower), from removing the garden.  The last time he removed the majority of the phloxes and deposited them 100 yards away with all the tap roots neatly severed.  Part 2 will be placing chicken wire over a large part of the garden to keep the marauding antlered rats frustrated.  It's the end of the hunting season and they will soon find their way back here.

So your garden goes right down to the road Anne? A great treat for passers by but the snowman is a real danger. I hope the red markers work well. Maybe a slab of Christmas cake and a word to the wise as well?

For me the rock garden itself, is as important as the plants. The plants are very beautiful as they flower, mostly also nice when they don't flower.
A rock garden nicely constructed is beautiful throughout the years and enhances the beauty of the plants growing in it.

This is a picture of the north side of my big rock garden, that side I totally renewed. There are almost no plants to see yet (only little ones, that you can't see), but I love these marble rocks, they look good even without plants. Actually it's a big crevicegarden, but you don't notice. Underneath the rocks there are hundreds of roof tiles, vertically arranged, so all the plants grow in crevices. 8)

There are big stones in your rock garden, Astragalus. ;)

The large rocks are natural.  The property is a series of stepped ledges and outcroppings ending in a small cliff.  The wall are man (woman) made, but there is one huge rock I moved with the aid of gravity, a very long crowbar and every principle of physics I could remember.

You must be lucky, Astragalus,  the only natural stones I can find here are little boulders.
I must admit I am lucky too, they are dismantling the old little road in front of my house. A new road is needed.
Underneath the old road, there are tonnes and tonnes of rocks.
So I asked the workers in a friendly way if I could have some rocks.
'How much', they asked. 'A truck load ?'
No problem, the result you see in the picture.
15 tonnes of rocks for free ...
I gave them some alpines and they were as happy as I was with my stones.

A nice project, Annew.
If you want some advice, for the finishing touch, I would use some stones in another way. I hope you have some left.
Just smash the stones into small pieces of different calibers and use these as top dressing. In this way, the whole thing will look more natural.

As I was reading today I remember the seeps on rock cliffs and scree slopes in the Oregon and Washington Cascades.  Has any one tried to replicate a moist spring, seep, type crevice garden?  It sounds like a fun challenge.  Water features are common in many gardens here in Oregon and a modified water garden could do the trick with just a trickle of water verses a stream of water. 
Winter is here in force now with 28 inches of snow at my cabin now and will not see soil for another 3 to 4 months. Lots of time to plan.

Snow, beautiful snow at last.  Only 8" covering the garden so far but it's a step in the right direction.  2' and up makes the deer flounder and they will keep out of the garden because it's so steep.

It's not that big, but I have found a spot to try out my new stones that I got from the people that are building the new road.
It's a pleasant stone to work with; of course it's easy if you have a big pile to choose from.

I couldn't wait to plant some Saxifrages on the north side of this little crevice garden. These Saxes are amongst my favorites and so they deserve to grow in this new creation. A picture of little plants of Sax. 'Allendale Charm', 'Your Song', 'Laka' and 'Cumulus' planted today between the rocks.

Also an ordinary primula  my son Lucas (5 years old) squeezed between the rocks of the path beneath the rock garden.
I hope he also will love rocks and plants.

Your son, Leiomurus, once he sees his little plant growing happily, will soon get the "bug" we all suffer from and be a keen gardener in no time at all.

I like that path too Maggi as it shows what is clearly now a garden and not just a pile of rocks. I'm looking forward to seeing the new spring plantings and how they will soon colonise this scree or moraine. :)

I do my best for my plants because they do their best to flower in unnatural circumstances (the weather), so in return I try to give them a natural home that also protects them.  If the 'home' looks good, it's a bonus. ;D
I hope the plants will respond with marvellous flowers ..... and prosperous growth. 8)

I even put a Dionysia for a while in this rock garden to take a picture and it looked good over there.
Of course I didn't leave it there ..... :o

An update on my crevice bed, now known as the Steggerhorn. The top layer of sand has been applied, and a few plants put in where needed to plug a gap in the ends. I'm intending to wait for another settling period, then plant up (I'm going to need more plants!), top dress with gravel, then with the remaining broken up stones, as I don't think there will be enough of the latter to top dress purely with that. I hope it will still look OK. Lastly I'll direct sow the seeds I got from the exchanges. The labels are temporary; when I've finished planting, I'll take photos of the 4 aspects and label the plants on the photos, before removing them.

It looks great, Anne!   The pictures are very tiny - it would be nice to see bigger versions and really appreciate that design.  I have a rather poor excuse for a crevice bed and should redo it one day.

On the subject of Dionysia, I thought this was very interesting:

Crumbs, Lori,  We've been trying to get the forumists to post smaller pictures, and Anne has taken the hint- please  don't encourage them to go backwards!

Anne's pix are a perfect size to open within screen size and of a large enough file size to allow them to be further blown up  by holding control and scrolling up if a larger picture is desired - I reckon the detail to be viewed there is pretty good!  :)

Smashing job Anne, it looks great. You were so lucky to already have the stones to hand though. I fancy having a go at something similar and as we were passing a quarry last week I popped in to have a look. A couple of tons of mixed size rockery stone would likely cost me in excess of  a couple of hundred Ł's and delivery and off loading another hundred (a return trip of around 40 miles). Perhaps I could ask Luc if he could scrounge some for me from the Belgian mountains :P

I think I saw an article in an AGS Bulletin some time ago written by Richard Horswood about a crevice bed he constructed from broken concrete paving slabs he got from a garden centre. I must ask him more about this next time I see him. Would lack the texture and the differing thicknesses of real stone though.

It's amazing how a (rather refined) pile of stones can look so exciting! It looks very good now 'stegosaurus' is bedded in and it fits a corner of the garden like that to perfection. Must have been fun to make.

Lovely crevices there Anne and it will be great to see them planted. Let us know how the direct sowing goes especially with smaller plants. I haven't had much joy with it except with Gentiana verna. Saxes, androsaces, primulas and many others have not germinated that way. It would save so much time and energy - and space - if they would. Lessen root disturbance too of course.

This comes under the heading of "Too soon old ..... too late smart".  I found someone with a very serious backhoe and hired him for a few hours.  In an hour he did a season's worth of digging and preparing on the back of the cliff for the rest of the crevice garden.  Then he moved all the rock I had planned to move plus huge slabs of rock up to 2 tons that I had never planned to move because I didn't think it was possible.  Now I can concentrate on filling the spaces left with mix and making many crevice gardens.

I don't really know how to measure it since it will go up the back of the cliff too.  It's a large enough area that I'll be tackling it in more manageable sections to keep it from being overwhelming.  I also have to plan my access routes so every part can be reached safely.

Understandable, David.  There is a wide range of foliage and bloom and some of them are excellent garden plants with a little extra preparation.  Others require very specific placement, or object to northeastern summer conditions, or it's almost impossible to find the seed.  I think they're all worth trying.  Sun is a prerequisite for most of them, meaning sun for a good part of the day.

Try Alplains - they have Phlox http://www.alplains.com/ (http://www.alplains.com/)  I  bought some seed from them this year, not Phlox, good service, took a while to arrive but owner kept me informed.  Good germination so far - though I didnt buy Phlox, more Delphinium

I used to get phlox seed from Rebecca Day-Skowron when she ran her seed business.  The seed was expensive and you would get a small amount of seed but every one would germinate - really amazing seed.  Alan Bradshaw of Alplains supplies wonderful seed of some really rare species.  I wouldn't count on finding it in Society Seed Exchanges.  I can remember collecting phlox seed, an arduous chore.  So much bloom, such prickly foliage, so little seed.  I understand why it's relatively expensive.

Hi Anne ,this subspecies grows in Southern Spain more exactly  in the "Sierra Nevada" .
It is always densely tufted with grey keeled leaves. Later in the season and when not in flower it has a very grey appearance .
Sometimes you can read that it is not reliable in flowering . It is the first time that it's flowering for me after 3 years of cultivation.
I am quit happy with it  because it makes this nice grey cushions to.
Maybe ( i am not shure )it withstand better dry conditions because of his Spanish roots ?

Construction on the back of the cliff was going great guns until I had to stop and tidy up for a garden visit.  It was all blue sky, sun and cool breeze for the day and we had over 100 people, some of whom had to be restrained from going into my work area because they wanted to see the plants "up close and personal".  April was so cold and dry everything was really slow getting started.  Eritrichium howardii has only a few blooms but is still budding and the genistas are just starting, very strange.

The garden was open for the Garden Conservancy while everyone was having a fabulous time at the Czech Conference - very poor timing but a commitment is a commitment.  During the open garden one visitor pointed out that there was lots of room in the crevices for more plants.  My reply was that as an optimist I was leaving room for growth.  Actually it's a bit overplanted with the idea that a few things might die, and thanks to the antlered rats they usually do.  Lately there have been many moose sightings in our county (would be 10 times worse in the garden!).  The Edraianthus montenegrinus is a beautifully dark purple flower, similar in color to E. serpyllifolius.

Some self-sown seedlings of Symphyandra wanneri and a picture of Lewisia rediviva alba.  I finally found (made) a little overhang in the crevice garden and the lewisia has decided it likes it there.  It has come through two winters.  I included the Asarina procumbens because it looks great against the rock and because in a dry garden it's not a thug.

Anne - I am really excited to see that Convolvulus flowering as it is one of the species I brought back from the Czech Republic. I will certainly be happy if it flowers like that (C. boissieri only flowers quite shyly for us). I have a nice little crevice between two blocks of tufa...!

Tim, what you can't tell from the picture is that Convolvulus suendermanii is planted in a crevice on a slope.  The crevice is v-shaped and the top of the vee is filled with gravel.  I've done that with a lot of the crevices on the back of the cliff so that the plants won't be recessed and can be seen better.  Convolvulus boisseri blooms pretty well here as does C. compactus.  I have difficulty with C. assyricus, both in flowering and longevity.

Tim, Convolvulus suendermannii is here absolutely hardy and requires no special demands. I think, other Convolvulus-Species are more difficult.

My Convolvulus suendermannii has been growing 14 years now without any protection in my rock garden. Here are two pictures from previous years (this year it is not yet blooming).

Looks wonderful.  Hope mine will do as well.
Tim, some pictures of convolvulus for you.  C. compactus seems to like lime very much.  It will develop very woody roots in time.

A local farmer happened to mention that he had a one ton weathered limestone rock in his field. It was scored with deep grykes.  Off I set in my van and it was loaded with a little difficulty into it.

I then got it out of the van and manoeuvred it into position in the garden. I can assure you it's never going to move again! Heavy isn't the word.

There's no alpine nursery in this country so to make it presentable for now, I tore up a load of Sea Pinks from the front garden and stuffed them into the crevices. I put back some of the protruding bits of rock that had been knocked off during the manhandling.

I can take my time and decide what I'll eventually put into it but the Sea Pinks will do temporarily. The bits of railway sleepers underneath will be covered in time by the heather.

Your rock makes quite a lovely display.
A few plants blooming now in the crevice gardens.  The unusual thing about the Oxytropis multiceps is that it is reblooming and still has seed pods.  The rebloom is a first.  The first picture has Moltkia petraea in the background and Linum spathulifolium in the foreground.  It makes a wonderful picture for the eye, not sure if the camera catches it.  Cliff Booker needs to be here photographing again!

I've come to the conclusion (with my pictures anyway) that pictures with lots of small flowers in a big area, like a meadow scene or even one with lots of small stones makes a big original file and when I resize with Microsoft Picture Manager to 640 x 480 it is over 200kb.  I tried compressing with the same program and found it came out too small to see much.

In some years (not this year so far )I have the same problems to Anne ....For this crevice I choosed a spot with more shadow .
But even then I can't grow al of them. I think a lot of Campanula's like a more loamy gravel and more moisture .

I agree, Kris.  Many campanulas really don't like drying out.  It stands to reason that if astragalus and other dryland plants like it here, the more traditional alpines may ask to be in someone else's garden.

But we are lucky Anne ......there are so many others who like it here or at your place......And we enjoy your dryland crevice very much. Here we could not grow many of them , Astragalus e.g.  is a real challenge here  without winterprotection  ....
But we keep trying anyway ...My conditions or something between your very dry conditions and the ideal conditions for most campanula's ....But sometimes there are  opportunities ........and I am so happy to discover and learn and this forum and this topic is very usefull .
I think that Campanula troegerae is a good choice for a dryland crevice . We see them growing in Turkey and I suppose that both troegerae and choruhensis are good choices for the dryland ? I don't know if you ever grow this both species ?

 It is true, Campanula troegerae is a good example of a drought-loving bellflower. It is in my alpine house and is almost kept as dry as Dionysia. But also for plants from the Alps such as Campanula morettiana it is too wet outside here.

I agree on your quote Anne , we al have our limits .....I must admit that I lost this Helichrysum several times in the past. This one is in the crevice now for two years and it get some winterprotection . (glas)

I keep discovering more alpine hypericums I haven't heard of - I do like that H. imbricatum; they seem a very underrated genus.

Peter Korn showed Helichrysum milfordae growing well on one of his sand beds, and also flowering well. He said that it does best planted near to a high water table - and his winter temperatures can be pretty low. I must admit I grow it with glass cover in winter, but it doesn't flower well for me. I wonder if they grow it in places like Tromso where there must be persistant winter snow cover?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on June 26, 2013, 07:11:58 AM
Kris, I don't provide any winter protection, only protection from deer.  If it were a white flowered ranunculus, I would probably do anything to try and keep it, though.  We all have our exceptions!  The only one I can grow is Ranunculus pyrenaica (spelling?), and it may be that the only reason I can grow that one is because it seems to be able to go dormant when the garden gets dry and then reappear in the spring.  There is no high water table in the garden.  What there is, is very, very deep crevices (in some cases up to 5'), and there must be some moisture retention there although I doubt the roots go that deep.  The one exception to that might be Claytonia megarhiza, whose roots seem to go on and on.

Kris, Phlox pulvinata is one of the easiest of our western phloxes to grow.  Another easy one is Phlox kelseyi.  It comes in white and various named purple forms (P.k.'Lehmi purple', and P.k.'Lehmi midnight').  The really great thing about P. kelseyi is that it will have repeat flushes of bloom when it's happy.  It does fine in troughs, crevice gardens, just wants good sun.  I think you can get seed from Alan Bradshaw of Alplains Seeds.  Phlox condensata is another winner but is not quite as easy to make flower the way it should.  Try as many as you can find, they are all wonderful.

Post by: astragalus on June 28, 2013, 09:41:40 PM
Kris, I've always had really good luck with Alplains seed.  He offers a very wide range.  I'd certainly try Phlox condensate again.  It's a bit more difficult but when you have some success it's worth all the effort.  Here it likes a very sunny crevice and it's in a fairly windy spot so there's good air circulation.  I'd suggest Phlox borealis if you want stunning color very early.  It is a hot pink and the earliest to bloom here.  Another suggestion would be Phlox diffusa from the Pacific Northwest.  It has many pale color forms, all sorts of pastels.

The only reason for that is the fact that we have very warm weather now and that I use the blue stuff since the beginning of march .

Thanks Cliff and Anne.

Was the trachelium grown from seed?  And if so, do you remember where  you got the seed?
I bought the Trachelium 16 years ago as a young plant. Unfortunately, there is no seeds here.

Two older plants in a dry stone wall:
Trachelium jacquinii ssp. rumelianum

Stunning plant Eberhard ! I did not see this plant before in the Flemisch gardens but it deserves to grow more !

Post by: ebbie on July 26, 2013, 08:16:39 AM
Yes Kris, Trachelium jacquinii ssp. rumelianum is a good rock garden plant. It is robust, simple and long-lived. Its flower is a magnet for bees and bumblebees. On the other hand, it requires space and looks after flowering somewhat messy.

I planted the Trachelium into a granite wall. But I think limestone would be the better material.

Must admit that I lost it in some years and this is a new planting Eberhard. 
But I choose a new spot now . This new spot is more protected and I planted it more in a vertical position . Another thing ....I filled the crevice between the tufarocks with a very lean mixture .There is no peat or compost involved .I choose a very mineral soil .

Here it is hardy enough without protection Anne .(must say so far ....because it looks like the winters are change a bit last years and it seems we getting harsher winters )   

But it is protected by a fence against the coldest eastern winds. I hope I am able to grow it the next years ....
We only saw it once on his natural habitat in  Crete when we are walking in a gorge.

This started blooming while we were still in the Dolomites and is just now beginning to go over.  Seems to enjoy sun and scree, where it will ramble through rocks, and the crevice garden.  My favorite of this genus is Collomia debilis v larsenii, growing on very steep screes.  It is soboliferous and the flowers are white with pale tones of blues.  It's a gorgeous thing.

I certainly think you could grow Collomia debilis.  Give it a rocky scree where it can ramble through the rocks, which is the way I saw it growing in the Wallowa Mountains.  The C.d. v larsenii might be more difficult.  It seems to be a snow melt plant, and I've seen it only on very steep slopes, probably meaning perfect drainage.  It also is fairly solitary, adapting itself to where there is very little competition.  It has stayed with me as long as three years (not long enough).
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on August 04, 2013, 01:33:14 AM
Maggi, the link you provided for Zdenek's plant of Collomia debilis v larsenii was perfect.  It shows the leaves so well.  They always make me think of birds' feet.  The plants I've seen (MT. Fremont and Mt. Baker in Washington) were suffused with an almost ethereal blue.  Difficult to describe, but unforgettable.

I've i.d.ed the picture I put on of  Zaushneria sp.  It's Zauschneria californica 'etteri'.  Are you able to put that on the picture?

Thanks a lot Anne . It is a very rewarding method of alpine gardening ....
The plants need some time to establish because I go for a very lean mixture and I am happy when they grow slow but stay compact. So I expect that this crevice is even better in 1 or 2 years .
I am happy to post more pictures in spring  :)

How hardy is Zauschneria californica "Etteri"?
Is it available in Europe?
Found only one nursery on the net.
@ Astagalus
Do you leave your plant outside during the winter?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on August 08, 2013, 12:22:42 PM
Yes, the plant is outside during the winter.  It is planted in a deep crevice in the crevice garden in a very lean mix which drains very quickly.  It is a young plant which has only come through one winter so far.  I can't vouch for the hardiness because last winter was a non-event here.  I think we were only briefly below 0F, which is extremely mild.  I have found that crevice planting seems to extend the hardiness of plants at least one zone.  The roots seem to be protected by the stone.  The zauschnerias are wonderful in the garden (dry, full sun) because they bloom when not much else is happening in the rock garden (August, September, and October and November during a mild fall).

Isn't 'Persebee' a little gem? It hasn't done it previously for me but this year it flowered really well in the autumn and I thought that was that, nothing for the spring but it's now COVERED in buds so like yours Kris, mine is a twice-a-year flowerer. Excellent value.

I hope you won't mind this little boast, last year's bloom in the spring. I had a second plant the same size but it was in the one trough I had to empty to move and it died except that later, I found a small layered piece which had and still has greenery so I'll try it again in a trough, the other still in a pot but needing a bigger pot now. :)

Wandering around the crevice gardens out of season always brings a few surprises and today was no exception.  The nicest surprise was finding that Physoplexis comosa, which I thought I had lost, was making a comeback.  The zauschnerias are really a lifesaver at this time of year, usually blooming until hard frost.  The arctotis has not bloomed but the foliage is gorgeous.  The Penstemon debilis bloomed in season so it was quite a surprise to see new buds.

1.  Physoplexis comosa

3.  Zauschneria latifolia prostrata ( not sure, label almost illegible)

I showed this before when it was just starting to bloom.  Here it is now and almost prime.  We're lucky that we have yet to have a killing frost so it may have time to even get better!  It's planted in a crevice between two huge hunks of ledge and is very happy.  So far not browsed by deer, unlike some of the daphnes.  It's too early to put up the protective wire screening and hunting season hasn't started yet.

Thanks, Cliff and Luc.  So far I've tried four different dwarf zauschnerias and really like them all.  Three of them are in the crevice garden and the fourth hangs over a wall.  They are Z5 plants and this garden has always behaved like a Z4b garden.  No Z6 plant ever survived and Z5a was really questionable.  The main reason is that the garden is very windy, especially fall to spring, and is on the "cold side" of the hill, facing NW.  Maybe the zauschnerias are thriving due to global warming?  It's been a while since we've had a winter with "normal" cold, which here should be -20F, with possible dips below that.

Zauschneria garrettii has been hardy here in zone 3 since 2004 (or maybe 2002 - looks like I bought 2 plants, according to my records).  The cultivar is 'Orange Carpet' and it stays very low here, though I'm not sure if the species in general would be considered dwarf?   I tried Z. californica but only once and in a trough, where it didn't winter over. 
Love seeing your garden!!

Lori, Z. garrettii 'orange carpet' is considered dwarf, growing almost like large ground cover.  I tried that one first because Z. garrettii was supposed to be the hardiest of the lot but much too large for my rock garden.  Z. g. 'Siskiyou Dwarf' has survived here and has bright orange flowers - stays under one foot.  Z. californica 'etteri' is definitely my favorite so far.  The flowers are a blood orange-red and very shiny.  Z. latifolia prostrata might be the best of the bunch if it would only flower better.  The growth habit is wonderful.  It's planted in a wall and is oozing over and under the rocks in the wall, but not much in the way of bloom yet.  Z. garrettii is supposedly Z5, I'm really surprised to hear you say Z3.  Maybe that's why these cultivars are doing so well.  There's another one called Z. g. 'Wayne's Select' that has silver foliage.  Hope to get that one in the spring.

Lori, you might try tht zauschneria again in the ground instead of a trough.  My experience here has been that you lose at least one zone when planting in a trough, unless it's super insulated during the winter.  If I'm not sure about the hardiness I put it in the ground where it can be better insulated against the cold.

Post by: Lori S. on October 01, 2013, 02:46:05 AM
Thanks for the info, Anne.  I will definitely try more of the smaller Zauschneria, now that I have rock gardens to plant them in.  (The Z. garrettii 'Orange Carpet' is not in a rock garden - it's just out in the front yard on a south-facing slope; I moved a few pieces of it around last year, finally, and they have survived as well.  It is very pleasing to have bright orange flowers so late in the season here!)

There are big crevice gardens, small crevice gardens en even very, tiny small crevice gardens like this one in a simple plastic pot.
It is really a 'crevice pot' because the little rocks are sunk into the compost as deep as possible, so most touch the bottom of the pot.
In this way there is more planting space, it looks nicer, you need less expensive growing medium, the plants will of course love to grow between the rocks, I also believe most love to grow together like in nature, it's easy to transport if necessary, there are more 'micro climates' .....

This one provides a little home for two Primula primulina, two Primula integrifolia, two Androsace neuwirthii and one Silene acaulis.
Of course, most are not fast growing, so the pot will be fine for several years. ;D

Hi Fermides,

Not really, I always make my own recipes. ;D
I'm also lucky to be able to choose between a lot of rock of different calibers and a lot of small ones ....
But I must confirm that all the plants in this crevice pot come from the nice Czech people.  ;)

Thanks.
When it freezes a little bit, I will not do anything. I do cover them now till March next year. When it will freeze for a long time, I will put the pots in my unheated veranda.
A trough isn't plunged either and the plants mostly come through the winter unharmed, which is normal since they come from the mountains. Of course, pots are much smaller, so they will freeze more.

I'm also planning a new crevice garden, or I must say I have already begun.
This picture is from the spot where the crevice garden will be, but now it's a complete chaos, because the stones I will use were already on the particular spot. :o
Of course, when the stones will be arranged, there will still be some chaos, but more a chaos with order .... ;D

It's like a big puzzle, and you must get puzzled to start with it.
Although there is 'something' in your mind, you never know where you are about to get.
You only have a vague picture.
The best thing to manage it, is to start without thinking and let your 'unconscious rock garden mind'  do most of the job.

This picture shows the new crevice with all the crevices filled with some rock garden compost.
I made the mistake to use a lot of red 'mine stone' chippings into my mixture, the red color doesn't match with the grey stones.
But by applying a lot of little broken rocks with a rather big calibre, this problem is solved.

Making the top dressing was the most work.
I had to break a lot of little rocks with a heavy hammer to have sufficient top dressing.
I always do that when I make a crevice, these are the only chippings that correspond with the bigger rocks.
If you get some chippings from a garden centre, they hardly ever match. You better make your own.
It has some advantages : when there are rocks with a more brown color, you look for a little rock with the same color to break and you use the chippings in the neighbourhood of that particular rock.  8)

The two other pictures show my 'breaking rock', my hammer and the resulting chippings. This is the only way to do it.
Also good for my muscles....but you must 'watch for your eyes'.

So, let's go on ...on the rocks ...

1/ Picture 1 : Here I have used the garden hose in order to settle the compost in a quicker way.
    By the way ; this crevice garden is called 'Crevice Garden Number 4'.

2/ Picture 2 : The same crevice with some chippings broken by my self.
    Of course, the end result will be different, because my 'subconscious rock mind' told me to change some things. ???

Post by: Leiomerus on November 24, 2013, 09:24:37 PM
1/ This is CGN4, almost in it's present state. With all those self-made chippings, what a work !
     I've made some more outcrops, so it looks better.
     I couldn't go very high, it's already a natural slope and I didn't want to hide the natural stones from the house, because they have practically the same color.
     Of course, maybe next week, I will suddenly think that some features must be changed, or maybe not. It all depends ...
     There are already some conifers to be seen.
     Today I have planted 18 Saxes in this crevice. This crevice will be an Allendale crevice, (with some minor exceptions) only Saxes from Mr Fairbairn.
     The other crevice will be devoted to Saxes from Karel Lang.

2/ Here you see a little bulb bed. There are only bulbs where you see the chippings. There are some step stones, otherwise I break my legs to reach the water tab of 
    the garden hose. The big rocks you see, will be removed when I'll have more bulbs.
    This bed is the division between CGN4 and CGN3.

3/ This is Crevice Garden Number 3, located next to Crevice Garden Number 1.
    The 'borderline' is indicated by the little Phlox you notice in front.
     CGN1 is now 1 year old and is made of many different rocks. Of course planted with mainly Saxes, but also some Androsace, Primula and even some Dionysia.
     The originally little plants are growing well.

4/ This is a view taken from CGN1.
    Now the whole east side of our house, is rock garden.
    My wife is very pleased. I don't need a ladder anymore to clean the windows. I simply stand on top of the crevice and I can reach every window.
    Now she likes me to do it.
    In the past she needed a ladder. ;D

Thanks, Luc.  This is the first time I've bloomed this one.  My mix is very, very fast draining but this one has the added benefit of being planted in a steeply sloping site.  That seems to have been the difference because I've lost the others which were planted in flatter places.  It's a xeric plant and too much wet is usually fatal.

Much too dry, I think.  Has your Astragalus loanus started budding yet?  It's gorgeous in bloom, the first time it's bloomed here.
Well, I'm just speculating, but it looks like your area normally gets more than twice the annual precipitation here (~40 inches vs. 16 - and a good proportion of ours runs off as snowmelt while the ground is still frozen).  I've only had one plant of Paraquilegia sp.(possible garden hybrid) and only since 2010, but given my "survival of the fittest" conditions, it must be pretty tough.  If you haven't grown it before, maybe it's worth a try?   ;)    My brief experience with it doesn't present a great example but it does spectacularly in Stephanie F.'s garden here in Calgary (what doesn't?  :o), forming large clumps, blooming extravagantly and self-seeding happily!
 
No, my Astragalus loanus is just starting to put out new leaves - no sign of buds yet.  It bloomed near the end of May last year.  The second, wimpy seedling is looking committed to survival now - perhaps it will bloom this year.  We're under snow again here, and may be until mid-week - last snowfall, I hope?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 03, 2014, 06:14:36 PM
Lori, I wasn't thinking so much of hardiness as I was of the conditions here - unreliable snow cover, humidity and summer mugs, full sun, wind and summer drought in a garden that can't be watered.  That's asking a lot of an alpine.  i never even considered trying it, but maybe someday.
Astragalus loanus is turning out to be a beauty.  It survived the summer mugs for two years, I'm hoping it will make seed pods this summer.  The leaves are covered with fine silver hairs and the flowers are huge.  Astragalus detritalis is just starting to bloom now, a nice hot pink.

Astragalus loanus really is special Anne - I am really envious having tried to grow some of these amazing legumes and like Kris and Luc with very limited success. They are worth any effort when you succeed with a plant like that! I have good hopes of Astragalus utahensis which has grown well in a pot in the past and maybe can gradually learn more of what they need. A proper crevice and tufa/hypertufa garden beckons!

Thanks Anne , I think you are right about the Paraquilegia .Drought is one of the enemy's of this plant.
I have planted it  on the coolest place in the crevice where only some evening sun is shining.
It is also protected against dry winds in summer or cold winds in winter (eastern winds) who destroy this plants in late winter.
Even in winter I thinks it is important that it never dry out completely. (but not to wet to )
I did see it growing in China in damp places and high mountains where temperatures never get that high ... Not a xeric thing in my opinion .......

Absolutely not, Luc.  I'm always hankering over the plants that you grow with such seeming ease that I can't grow well.  Primula and campanulas come immediately to mind, also the Kabschia saxes ... the list could go on and on.  I admit a tremendous fondness for all the pea plants, but many of them are difficult for me to keep for a long time.

That's wisdom, Luc.  When I first started rock gardening I tried all the "classic" alpines and had a large plant cemetery.  Then I grew as much seed as possible and tried a much wider range of plants, discovering plants that liked the conditions here.  I've learned to love the plants that perform well.  No two rock gardens are the same.

I agree, Ebbie.  It gets woody very quickly as it gets older and here, large sections of the older plants will die off in the spring.  But it makes a tremendous amount of seed and every year I will find a few seedlings from the left-over seed I didn't collect.

That's possible, Luc.  I've seen huge mats of Douglasia laevigata in the wild and it took a bit of exploring to realize that the mat was formed of multiple plants.  It appears to seed into itself.  It certainly doesn't make big mats in my garden.  Probably many of the plants on a rock gardener's "want" list are short-lived in nature.  I'm always fascinated on how growers with alpine/green houses improve on nature.  Their plants often look better without being subjected to nature's fluctuating affections - they live without droughts, floods, tearing winds etc., amazing.

Wonderful plants, folks!
Astragalus barrii is a cute one - reminds me of our native Astragalus gilviflorus, with the flowers peeking out of the cushion of leaves.

Linum cariense is a bit of a mystery to me.  It seems to winter over here, but after a few years, when it's just getting quite nice, it's kaput! What's up with that, I wonder?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 13, 2014, 10:40:04 AM
When Claude Barr discovered Astragalus Barrii he was in the midst of a colony of A. gilviflorus which is somewhat similar.  A. gilviflorus has larger flowers that are stemless, though.  I find it very very difficult to keep.
Linum cariense is a mystery to me as well.  It does so well in the beginning you think you have a winner, but perhaps the winter combination here of cold, wind and often no snow cover does it in. A pity because it's so lovely in bloom.

I think that many Linums are not so long living anyway .......Maybe this is a bit the same in nature , I don't know.
Many years I could not overwinter them in the garden but I keep trying because I had seeds (from different seedlists) and cuttings from my plant in the greenhouse. And now after about 4 or 5 failures I find a spot that maybe is better. Or I have a clone that is better ?
But we need more years of succes to have a party .....

Kris, it doesn't take that long for me to have a party!  If a plant seems happy and blooms well, have the party quickly because you never know what the next year's weather will decide to do.  Also, photograph often, maybr every day,  something I forget to do.  Good luck on the linums, I think they're all special.

After a tip from colleagues at Kew, we found at Wisley that Linums grow (and flower) much better and live a bit longer if you feed them more regularly than you might typically do for most alpines. Seems they are rather greedy! So a weekly liquid feed (low nitrogen, high potash) right through the growing season is what we did.

These are great crevice "filler" plants, just easy doers that act as connectors.  I'll put in more of them little by little and they won't interfere because they are not planted in long crevices where they could run.  Since these crevices are finite, time will tell if the plants will be successful long term.  The crevices are deep but not particularly wide.  Just another ongoing experiment.  My garden seems to be full of those.

Luc, that's a good idea.  I never thought of V. oltensis in relation to tufa.  Isn't a rock garden Forum a marvelous idea?

Very, very busy here.  I'm going to try some before and after construction pictures. (They'd be better if I remembered to photograph while working).  These are before and after pictures of the crevice gardens at the top of the garden.  Countless loads of mix and countless rocks set with the natural slabs of ledges acting as the "bones" and basically directing what I do.  It's more an act of listening than an act of
creating.  The last two pictures were taken today.  In the last picture you can see some rebar - that's marking the presence of a piece of ledge which is only 10" down.  It will tell me what I can plant there.  In an unwatered garden it would be easy to fry some things with so little depth of soil.

More pictures of rock.  And then plants.  The dianthus is planted in a natural crevice on the back of the cliff.  The globularia is happily creeping
and covering multiple crevices.  It has eaten several plants on the way but obviously it's the survival of the fittest.  The plants that can't protect themselves are planted out of harm's way.

A few more.  The Astragalus loanus pod is very fancy.  It's actually red but is so covered with white hairs that you can't really tell.  The Collomia debilis is a marvelous plant.  I've seen it in the Wallowa mountains above treeline growing in absolute rubble with no visible soil.  It just kept popping up out of the rubble so it must have a very extensive root system like the gem of the genus, Collomia debilis v larsenii.

Can't compete with these wonderful real life examples of crevice gardens but here are a few pictures of our display at the Kent Garden Show last year - 1. Deliberations. Mike and Hazel Brett, Peter Jacob (with the red hat - it was a cold May last year!) and, with his back to the camera, Paul Lewis who provided all of the troughs and a great deal of inspiration. 2. Half completed. 3. The crevice bed - over-planted I know but essentially for display. 4 & 5. The troughs.

These really are great ways of growing plants but I don't think too many viewers cottoned on to them. We are not doing this in 2014 but maybe another opportunity might arise in the future, and it was very stimulating for all of us who were involved.

Good to see lichens getting established on your rocks. Usually a sign of unpolluted air and gives an impression of age to your structure.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 23, 2014, 11:05:49 AM
The lichens have been there forever.  A Geologist once visited and immediately said the same thing, 'you have really pure air'.  The rocks that were uncovered during the digging out of the rock garden have also acquired lichens.  One steep slab of rock has a sheet of moss despite full sun all day.  It's rather treacherous to be on it even when it's dry.  One visitor thought I should be growing things on the moss.

Tim, I loved your 'crevice trough'.  Who gets to take that one home?
We had to remove a slate roof and I now have a lifetime supply of slates for troughs.  Tufa has gotten so expensive now that you're very careful where you use it.  Mine mostly goes into the tufa garden with new plants.

Tim, do you have a list of the plants in the big 'crevice trough'.  I tried but even under magnification couldn't read all the labels.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Tim Ingram on May 23, 2014, 12:31:17 PM
Anne - unfortunately the big crevice trough was put together in situ so we had to pull the whole thing apart at the end of the Show. We distributed all the plants between us! I haven't got a list but will have to look on the original image I have if there is anything that particularly stands out.

Amongst the more choice plants are Anchusa caespitosa, Lewisia rediviva, Saxifraga 'Southside Seedling', Lithodora oleifolia, Leptinella atrata dendyi, Dianthus microlepis and Verbascum 'Letitia'. Quite a few of these came from the superb alpine wholesale nursery W.H.G. Mann & Son in Essex, very close to where the Essex AGS Group meet, plus a whole lot of things we grew ourselves. I've written about it in more detail on the AGS website (if I remember rightly somewhere under 'Any Other Topics' and 'Local Groups').

This is something I could imagine doing on a bigger (but still relatively small!) scale at the Chelsea Show but it is impossible without quite a bit of support and we still have our own garden to manage too. Your garden just looks so inspiring - you must say if you are ever visiting the UK; it would be great to learn more about it.

This is another neat little pairing of plants from the display - Lewisia & Zaluzianskya. The great thing about doing this is the freedom you have to associate plants and make a picture, but of course it is instantaneous so not really realistic in terms of how a garden develops more slowly over time. I can imagine that you deliberate for a long time deciding on the best spot for many plants!
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 23, 2014, 09:12:29 PM
Tim, those are some great plants you put in that trough.
Yes, I do spend a lot of time thinking about siting the plants, because they will probably have to stay there forever, (or as forever as alpine plants get).
I played hooky once and went to Nottingham for the Conference and it was spectacular.  Once I got over the guilty feeling of leaving my garden at that time of year, I had a fabulous time, met wonderful people, some of whom I had "met" on the Forum.  Went on the pre-conference garden tour and that was so amazing.  I would love to come again another spring, both to see the English gardens again and to see the Scottish gardens I missed.  The plant show was incredible.  We simply don't have shows like that in the U.S.
Please tell me something about the plant you showed, Zaluzianskya.  I recall seeing that in a pot at the AGS Pershore Headquarters, but never learned anything about it.  Anything you can tell me about habit, hardiness and culture would be greatly appreciated.

Astragalus loanus is blooming heroically this year, and I suddenly "get" why rock gardeners might seek it out!

Dear Anne, Zaluzianskya ovata grows on partially shaded cliff faces at quite high altitude in the Drakensberg (see Hilliard & Burtt - The Botany of the Southern Natal Drakensberg), so it should be pretty hardy, probably similar to some of the Diascia species like D. integerrima and vigilis which we have found hardy with us. The flowers are rather wonderful with their red reverse, only opening early and late in the day. We haven't grown it long enough to test it properly in the garden but I'm not sure that many gardeners have found the genus that long lived. I wonder if it has been grown at Denver? (Almost certainly I would have thought).

I am smitten by Astragalus loanus that Lori and you have shown - only seen this once or twice at Alpine Shows but it's very subtle compared with some of the more colourful species. Really must keep trying these until I find a way of succeeding with them!

Mosses are a wonderful group of plants which can stand complete dessication for months and rehydrate in minutes. Bryophytes are not generally welcome in pots though.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 24, 2014, 12:15:35 PM
Lori, maybe this is just the year for Astragalus loanus.  Great pictures and I hope you get lots of pods for seed.  I'm down to two pods because we have been having grey, wet, dismal weather and this often occurs when the astragalus and oxytropis pods are forming.  The result is predictable and the pods will turn to mush although the plant usually survives - very frustrating, because A. loanus had such a bumper crop of flowers this year.  Your plant really looks fabulous.  Do you grow Astragalus gilviflorus in your garden?  I think you said that it grew nearby.

Tim, that Zaluzianskya ovata is a lovely thing.  I've not been able to get Diascias through the winter so far, so the hardiness for me would be questionable.  We are in a microclimate because of the garden being exposed to so much wind and frequently without snow cover.  It's great in one way because most alpines suffer without air movement,
but in the winter they usually have some snow cover and are protected.  I would imagine that it's been tried at DBG because they have pioneered so many South African plants.

I think mosses are lovely, but not to navigate on!  It grows in full sun and wind on a very steep section of the back of the cliff and I don't know why it only grows there.  I can maneuver on either side of it but I basically stay off it even when it's dry because it's possible to reach in from each side and remain in one piece.  I've learned the hard way not to work on rock when it's at all wet - put moss on top of that and you really have the 'slippery slope'.

V bright, sunny day fro a change.  Bad for photography but I had to take a couple anyway.  The Penstemon debilis is an absolute gem to my eye.  The leaves are really blue.  It grows in a geographically retricted area and one that is extremely hostile, if not perilous, to seed collectors - in a steep sliding scree atop perpendicular cliffs and below other perpendicular cliffs.  The seed collector in this case was Alan Bradshaw of Alplains Seed Catalog.  I hope everyone is well acquainted with this catalog.  P. debilis actually put out some flowers in the fall and then the temperatures bottomed but it survived and has many, many buds.  You can see the effect of our recent damp and rain on the leaves but it's still beautiful.

This is certainly becoming dianthus time.  They seem to like full sun in the natural crevices on the back of the cliff.  The labels were lost to deer.  A couple of them are even fragrant.  It's also convolvulus time.  The one shown is in a crevice on the back of the cliff and looking happy.  This site gets sun all day long and a lot of wind as well.

The convolvulus is astonishingly beautiful. I bought this plant last May from Ota Vlasák but unfortunately haven't kept it - it will be top of my seed list next season! Isn't it a problem? Once you see plants growing where they are so well suited you just have to make a garden that gives them the same. We have a dream project of removing an old leyland hedge and replacing it with a tufa (or hypertufa) and/or crevice garden, and this would be just the place for such plants.

Oh yes me to Anne . Here they like the most sunny places in the tufa -crevice garden. The smal crevices between the tufarocks I filled up with a mix of sand and grit. No other stuff ............

Post by: astragalus on June 04, 2014, 02:38:29 PM
The convolvulus seem to like things very lean so you have the perfect idea, Kris.

Arenaria is pictured growing in a trough but it is also in bloom in the crevice garden.  It's very interesting how this starts growing in cultivation.  In its native haunts, it forms a dome.  Some of them get sizeable and must be at least 50 years old.  In the garden, it often starts out life with a lumpy shape (sometimes almost a mat).  After a few years it starts to bulk up instead of spreading and it will form a small dome. It's very floriferous.

Lesley, I grow it in a very lean mix that's fairly rich in minerals, no humus.  I've seen it in the Wallowa Mountains and it's beautiful there.  In the garden it seems relatively easy.  Maybe your mix is just too rich.

Thank you Anne, I'm sure you are right. I have several small potted plants - I think they were originally from Ratko seed - so I'll try a couple potted in a harder mix and at least one in a biggish trough with a scree-type mix. I can't resist that super blue. :)

The crevice gardens are continuing to please.  Every day's morning tour finds something to photograph.  You can't photograph much beyond 9 a.am because the sun is so bright the photographs are totally washed out.  Lately, of course, we haven't seen much sun - just too much rain.  The potentilla and helianthemum are in a crevice at the top of the cliff - nice size for distant viewing.

I saw the Wisley crevice garden before the Nottingham Meeting, when it was quite young.  They had put in many plants but crevice gardens typically swallow up the plants because of the amount of rock.  The new ones always look empty.  I'd love to see it again, it doesn't take long for happy plants to reach a size you can actually see at a distance.

Hello Tim , the basic components of this crevice are also sand/grit  with some extra bims and a very smal amount of clay . But for this one I added a bit of leaf and peat . In some years we have some very dry periods here in summer.....(and much heat ) It is a very difficult one to grow here and it is the first time that I could achieve such result. But I agree with you , I love this plant ! 
And I hope for seedlings like in Bob's garden !

A few things flowering (or not) in the crevice garden.  Zuaschneria californica v Etteri has been flowering gently sinc the end of July, way ahead of schedule.  Hopefully, the heavier bloom is yet to come.  Also Zauschneria californica 'Wayne's Select', new to the garden this year and much sought after for its silery foliage.  Sharp eyes might spot the single bud showing so far.  These plants are really for late August and almost til frost.

This is Daphne x hendersonii 'Rick Lupp', which is supposed to have arching branches and is just starting to show this characteristic.  The foliage is quite wonderful, maybe it will flower next year.
I'm hoping in time the branches will arch over the rock for a very different daphne effect.
The Petrophytum hendersonii is just coming into bloom.  It is very nicely starting to run along a narrow crevice.

***  This has been reidentified by Phyllis Gustafson and Panayoti Kelaidis as Petrophytum cinerascens.  The foliage of P. hendersonii is bluer and the flowers are short, rather tubby and not on arching stems like this one.

Astragalus amphioxys 'San Felipe' reblooming.

Thanks, Maggi.  I think Max would do a great job were it not for the leash law we have in our town.  If we fenced the place to keep Max in bounds that would work as well.  But we would have to win the lottery first.  We live on rock and it would be incredibly expensive to fence, requiring dynamite to make most of the post holes.  The only place we have fencing is down at the road where the stream garden is - it has been a joy gardening behind an 8' high fence and no deer inside.  I always overplant figuring the deer will eat a large percentage - at the stream garden I may have to thin out the plants!
A beautiful and very impressive wolf hybrid.  Here they are not even legal in a lot of states.  We have coyotes here but they don't make a dent in the deer population, though they might take care of an injured deer or fawn.

It works here but be aware the highest wire has to be 7'or 8'( with a spacing of about 2') otherwise they jump over it!

I'm a bit late in finding it - the SRGC twitter timeline used to show several days worth of "stuff" but now it only seems to be a few hours so it can take a bit of searching to find such gems!

Panayoti was here a couple of days and saw my Petrophtum "hendersonii" which turned out to be P. cinerescens.  He told me that the latter is actually much rarer.  The zauschneria is still blooming.  We've had only light frosts so far.

Flowering in my crevice garden at the moment;

Celmisia hectorii hybrid (ex Hokonui Alpines)

Celmisia semicordata hybrid (ex Hokonui Alpines)

Celmisia brevifolia

Anaphalioides bellidioides This plant was propagated from a cutting collected locally from the Otago Peninsula.

Lovely plants David.

Isn't this Forum a brilliant resource? I've spent a very dreich afternoon re-reading every post on this thread and have made a note of over 100 species and am now plodding through The Plant Finder to find any possible UK suppliers. Would it be news to say that so far in the "Who May Have It" stakes Aberconwy Nursery is leading by a country mile?

So many brilliant plants and so much high quality rock work to see especially from Anne Speigle, Leiomerus, Kris De Raemaeker, Ebbie, Anne Wright and Ian Christie to name a few. Speaking of Ian Christie, in September 2012 he showed that he was in the early stages of working on a new crevice bed built over peat blocks. We never saw the finishes article Ian, it's time for more pictures.

Why have I listed enough plants to fill the Wisley Crevice Garden? Well, I'm extending a rock bed I built last year and will be including a small crevice bed in it so am going to need a few plants! Now to the Troughs thread.

Thanks, David and Kris,

The crevice garden is really a big experiment. I had some help from Dave Toole with the initial design and construction but the substrate I chose was a calculated gamble. It is crushed, weathered basalt from a local quarry that contains a lot of fines and clay. It seems to have worked on the whole. Unsurprisingly the plants that are flourishing best are those that grow on stony riverbeds and some are beginning to become a bit weedy notably Geranium brevicaule, Parahebe lyallii and Anaphalioides bellidioides. However most of what I have planted seems to be growing though I have had a few failures. I have another rock garden that is basically a raised bed of soil where I have planted some of the larger shrubs and herbaceous species that are not strictly alpines. It contains mainly hebes and a couple of Celmisia mackaui plant which are all doing well. (and seeding prolifically). I also have a collection of alpines in big clay pots ( 5 species of dwarf Carmichealia and some more Celmisias plus a few odds and ends. It is very much a matter of moving the different species around around to see which site and style of cultivation suits them.

Hello thanks everyone for comments, I should have said that the peat blocks came from Sweden Bob Potterton kindly delivered them to Ron at Lamberton then we picked them up on a very windy day the car was full of peat dust for weeks Ann was not amused. I cut the blocks into slices with my chain saw so that I had more material to work with the original large size as we got them would not have worked so well.  I will post more recent pictures once the rain stops have had lots of problems with moss growing now has anyone any ideas how to get rid of moss have tried several methods, cheers Ian the Christie kind.

Things are wrapping up for the year despite the warm weather off and on.  It's mostly removing all leaves so the chicken wire can be put over the garden.  Bambi has been very active but our hunter got an 8 point stag yesterday, unfortunately just a drop in the bucket.  The hoof prints are all over the garden including all the crevice gardens.  There was a big print between two Eritrichium howardiis, right next to the one that seeded itself in a piece of tufa.  It has yet to bloom.  In my late afternoon tour today (which explains the picture colors - a very gold sun slants in from the west at this time of year).  Mostly leftover blooms now but two interesting finds - pods have formed after the 2nd bloom on Oxytropis multiceps, and one bloom on a gazania which hadn't bloomed at all.
1.  Gazania
2. Daphne velenovskyii 'Balkan Rose'
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on November 10, 2014, 09:31:37 PM
Elsewhere in the crevice garden:

1.  Eritrichium howardii self-sown in tufa and almost a victim of Bambi's hoof
2.  Oxytropis multiceps pods forming after second bloom this year
3.  Zauschneria sp (probably 'Siskiyou Dwarf')

Kris, your trough is wonderful.  I also like the way you seem to have integrated the trough into the garden, it looks very natural.  I think the large troughs are the best for plant survival in a cold climate.
What are the measurements?  You seem to have found room for a lot of very good plants.  Do you protect it in any way during the winter?

Post by: rgc on November 23, 2014, 02:51:41 PM
Hi
In the last couple of days, I have made my first attempt at building a (very) small crevice garden. The scans are attached with some trepidation. Two views, the front which is south facing (but does not really get much sun at this time of year due to neighbouring houses) and the side.

The stones (rocks seems too grand a word) used to build the crevice are the re-use of some flat and relatively thin stones that I have been using as stepping stones around the garden for many years. (Bought round stepping stones from a garden centre to replace them in the rest of the garden.) The compost is 50% of my quite light garden soil plus 50% horticultural coarse grit.

Having a lack of patience, I added a few plants to see how they would get on. They are:
a Primula marginata 'Adrian Evans' that was displaced by the building of the crevice;
offsets from Saxifraga paniculata cartilaginea;
offsets from Saxifraga 'Grace Farwell';
offsets from Sempervivum arachnoideum;
a Gentian saxosa seedling (I have lots);
Raoulia australis.

More compost has still to be added to most of the crevices and I intend to do the main planting in (very) early spring.

Thanks Anne. Sorry for the late reply , we where on holiday the previous week. I used the same rocks as the ones I used for my crevice .
Actually this is my smallest trough. I try to give dimensions later on . Last two winters where very warm here  but in cold winters I wrap this trough  with bubble foam when severe frost with no snow is expected. Yes I give this trough a cover but I do this as late as possible. I just putted  a cover on them this weekend. And already in mid february or end february at latest I remove this cover. Offcourse depending on the situation wich can be very different from year to year. This trough is mainly devoted to Androsace , because I can't grow the most of them in the open garden.

As I proceed through my 70's I can't help thinking about what I've never grown and how long I might be able to continue my gardening interests before time catches up with me. With this is mind I'm now growing far fewer bulbous plants than I used to and trying to grow more alpines. Over this year I've developed a new rock bed the end of which will be a small crevice which I have yet to finish but aim to complete so that I can buy some plants, to add to those I'm growing from seed, at the South West AGS Show at the end of March 2015. Here's one from seed, and apologies for the fuzzy picture, struggling to open fully in the very wet and grey days typical in a maritime climate, Androsace albana, I think?. Sown October 2012 from AGS Seed Ex 11/12-1303. I note from Smith and Lowe that this will probably die after flowering, should have read that before I sowed them :(

Finally a free day to spend covering a large part of the garden with chickenwire.  It has to be raised off the ground or the deer will walk all over it.  I've been using the u-shaped wire supports from old political signs, but as the garden keeps growing (when I'm not looking), I no longer have enough.  This year I had to get quite creative as you will see.
First, a picture of what happens when the garden is not covered.

We had some old wrought iron chairs etc waiting for me to paint and make some seats, etc.  They have now been put to work.  I also have used the iron chairs from the terrace despite protests from my husband.  I pointed out that they sit outside all winter anyway so they wouldn't be hurt by a temporary change of location.  Also upended  all my work buckets to keep the wire raised. The garden now looks rather strange but it will stymie Bambi.  Even the back of the cliff is now protected, and that was difficult.  Sharp eyes will see the daphne still with small flowers under the wire  (D.velenovskyi v 'Balkan Rose').

Amazing bit of ingenuity Anne, I respect your motivation and hard work. I have heard some reports that wolves are being reintroduced into the Northern United States, to bring the ecosystem back into balance. Do you have wolves there?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on December 30, 2014, 12:14:54 PM
Don't I wish!  We don't have wolves yet - they would make a huge difference in the deer population and in a short amount of time you would never see deer in the open.  With predators around they would have to revert to their earlier habits.  We have coyotes but they're much smaller and would only be able to handle a disabled fawn.  I've heard that mountain lions are slowly moving eastward and that would certainly make a difference.  In the meantime it's impossible to garden here without resorting to fencing or some sort of winter covering.  The biggest frustration is finding pieces of plants left here and there, even acantholimons are not safe from their daily raids.

In for a brief rest because a new project was started today, a tufa crevice garden at the back of the cliff.  It will join the rest of the crevice garden when finished.  Two of the rocks are already planted thanks to our recent tufa workshop that Elsiabeth Zander talked about in her blog.
This is just the result of one morning, so very early stages.  In my head, it is completed and flowering of course!
Elsewhere in the crevice garden, Onosma caerulescens has started, and all the daphnes are beginning to open.

Last shots of the day.  Worked on the tufa crevice garden and it's coming along well.  Much time being spent tamping in the mix and tufa crumbs saved from cutting the stone, and then watering it in.  Everything here is like dust.  By tomorrow I'll be able to go back to tamping.  This is in lieu of letting it settle for a year.  I'll keep putting more mix and crumbs in before planting.
Finally quit at 5:30, too tired.  Wish there was some sort of law that said gardeners don't have to make dinner during garden season!  Yawn.......................

Planted on the top part of the tufa garden early this morning and covered it with some screening because it's in full sun.  Won't be able to plant again until this evening.
Leaving in two days for the NARGS Annual Meeting in Michigan and questioning my sanity.  I hate to be away for 5 days at this time, but it will be worth it.
Posting some daphne pictures even though not yet in prime bloom.  The air on top of the cliff is heady with their scent, just wonderful.  The second pic ture seem to be another form of D. velenovskyi.  It differs from 'Balkan Rose' but is also lovely.

Thanks, that compliment means a lot because I took the photos.  Usually Joe takes them because good photography takes more patience than I have.
Another great little plant below., Astragalus barrii.
And of interest is two kinds of foliage on plants of Lomatium grayi.  Same plant but one has much more dissected foliage.  That one seeds itself under the plant's skirts.  The other one, with the coarser foliage, self-sows in the general vicinity of the parent, and more plentifully.  Guess I'll never know why.

This is just the result of one morning, so very early stages.  In my head, it is completed and flowering of course!
Elsewhere in the crevice garden, Onosma caerulescens has started, and all the daphnes are beginning to open.

You did this in one morning? It would have taken me weeks! :o

Thanks so much, Ebbie.

Lesley, the tufa crevice garden is not finished yet.  Due to impatience I planted part of the top third.  It won't get disturbed by the next step in construction.  Which will be immediately after the Meeting in Michigan.  They will be selling tufa there but I can't very well bring it on the plane.

I can sympathize with your plight re: the daphnes.  You should have seen me at Nottingham where there was no one to do a phyto.  That meant no buying plants at the wonderful sale, not to mention at Robin White's garden where he was selling some wonderful daphnes.  I wasn't willing to risk smuggling them home.  Too law abiding, I guess.

Hi
Last November, I started building a south facing crevice garden and posted my first effort in this forum a few months ago on 23rd November. Since then, I have extended it and the result is attached. Its planting includes a dozen Kabschia saxifrage plus aethionema, androsace, primula marginata, sempervivum, lewisia, other saxifrage and some dwarf primula, dianthus and aquilegia amonst others. The plants are all still small, but will hopefully develop and give a good display next spring.

Managed to take the picture in a break from all the rain we have been having.

Any suggestions for improvement, warmly welcomed.
Bob

More from the crevice garden where everything is blooming at once because of the heat.  The Cytisus x kewensis is establishing itself in a very deep crevice between 2 huge pieces of ledge which seem to protect it.  The hedysarum is not in bloom yet but the buds are so beautiful I had to take the picture.  The astragalus and oxytropis are actually in a trough but couldn't find the trough thread, sorry.  Astragalus barrii has been in bloom for 3 weeks and just keeps getting better.  It likes the heat much better than I do!

Many thanks Luc, Cliff, Lori.  I think the hedysarum buds are just as wonderful as the flowers.  Wish we had a long cool spring this year so that things would last, you wait so long for the garden to wake.
Paeonia mlokowitschii and Paeonia tenuifolia only lasted a matter of days and they were gone.

Long work day w/perfect working conditions.  Rained last night, cloudy most of the day.  Tufa crevice garden#1 is  98% done and planted - just need to add tufa crumbs and mulch.  Pictures show it almost completed and preparation started for tufa crevice garden #2.  This is a lot of fun to do.  Have already started cutting pieces of tufa and it's quite irregular and unexpected so the plan just evolves according to what the stone shows me.  Very different.  Junellia micrantha survived in a trough so I bought one in bud to put in the tufa garden, heavenly fragrance.

Post by: Tim Ingram on May 17, 2015, 07:14:54 AM
Isn't Edraianthus pumilio a good plant! The equal of any choice androsace, or even astragalus ;). Just the perfect combination of foliage and flower. It grows well and self seeds in our sand bed. The Hedysarum is a great looking plant too - will be really interesting to see the flowers when they open - it reminds me a little of Ebenus, and these legumes are fascinating and so little grown. I've just planted some seedlings of Aquilegia jonesii in the sand bed and tufa - what chance that these might grow away and flower?? Other aquilegias, like campanulas and edraianthus grow really well here.

Very exciting to see what's happening in your garden Anne - I could wish we were surrounded by rock too.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 17, 2015, 12:09:45 PM

Tim, I agree with you about Edraianthus pumilio - it's really a winner but I have to admit to liking E. montenegrinus even better because it has such a deep color.  The hedysarum starts blooming at the base of the bud and will have many flowers this year, cream color if I recall and a wonderful contrast to the fantastic foliage.  I've seen Aquilegia jonesii in nature growing in limestone rubble very happily.  I've never seen it in cultivation completely approximate the deep color nor the size of the flower, and that certainly includes in my own garden.  Probably Cyril Lafong grows it to perfection, but for lesser mortals, not too likely.
What are you growing in tufa?  I need more ideas for the next tufa crevice bed, please.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Tim Ingram on May 18, 2015, 10:40:05 AM
Anne - we only have a couple of pieces of tufa and are growing just a few plants such as Helichrysum coralloides, Dianthus 'Conwy Silver' and one of the very small daphnes in them, so I can't give much advice - but Jiri's wonderful tufa cliff in the Czech Republic is filling up with so many interesting plants. If we could find a source of tufa, plants like saxifrages, choice primulas, gesneriads, rock ferns, Physoplexis, and a host of other plants would find their place (almost like an Impressionistic painting). So if anyone is interested in importing tufa from Canada ŕ la Waterperry let me know ;). In the sand bed the tufa gives a sort of focus and the combination of the two works very well even on the smallest of scales like this.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on May 18, 2015, 11:04:50 AM
That's a real color feast, wonderful.  I think the difference is that mine can't be watered through the summer heat.  I have to hope that roots establish quickly although we have been having drought conditions at the very time of year that rain can be counted on.  My tufa garden will have a number of dryland plants as a result.  Time will tell how well it will work.

Calandrinia caespitosa - happy so far but will have to see what happens.  The plant came from LaPorte Avenue nursery in Colorado, where Karen Lehrer and Kirk Fieseler have been propagating some Patagonian plants, such as Junellias.  I loved seeing this calandrinia in nature, so primary in color.
I put this one in the new tufa crevice bed.

It's a matter of trial and error to find out what works and what doesn't Anne.  Sometimes, things go wrong when you least expect it and on other occasions plants that are supposed to hate lime establish wonderfully on tufa.  Nature has it's own rules and plants don't read books...  ;D ;)
It's great fun though, growing in tufa.

Calandrinia caespitosa appears to be making seeds so hopefully it can be kept going.  Sorry, not a good picture.
The Hedysarum candidum is now fully in bloom, a bit floppy after a brief heavy rain, but still gorgeous.
The last is a lovely penstemon from seed which turned out to be misnamed.  Don't know the species.

Here's a great picture I've just been sent by Andrea Patey in response to my 'Comment' in the latest RHS Garden. This is a crevice garden made by her brother, Terry Hatch, over from New Zealand and making use of a whole lot of left-over tiles. If that doesn't turn a lot of gardeners over to 'rock' gardening I'll become a bricklayer ;). Just brilliant I think.

Another nice astragalus in bloom plus the first color change for the flowers of Eriogonum umbellatum ssp porteri.  There aren't that many truly alpine eriogonums and this is a great one with many color changes as the flowers mature plus the leaves turn a deep burgundy when the weather gets cold again.

Much as I loved Andrea's picture of a crevice garden, this is the real thing :). So lovely to see those plants growing outside Anne - I think the centaurea is one that Jon Evans showed in his pictures from the Wimborne AGS Show, with a comment that it was difficult. The answer: make a really good crevice garden! We've got the eriogonum growing in the sand bed but so far it is very small - would very much like to grow more of this genus.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on June 03, 2015, 11:07:11 PM
Tim, the eriogonum shown is pictured in its first color change from bright yellow.  It will keep changing until it turns a deep rusty red.  It's a true alpine and amenable to rock garden culture.  All in all, just a great plant.

Post by: Maggi Young on June 04, 2015, 10:15:44 AM
Ian is very fond of Eriogonums and has raised several from seed  but they have never performed well here - I think the climate is not good enough in summer to ripen them for flowering.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on June 04, 2015, 11:25:42 AM
Maggi, they really need dry air, which I don't have during the summer either.  But the one constant here is air movement - this tends to be a very breezy garden most of the time.  I think that helps getting away with humidity if the air is moving.

Such a wonderful time.  Things keep popping into bloom and every day is exciting.  Moltkia petraea is starting and it has also self-sown into some crevices, lovely.
I've made a good start on the second tufa garden and now have to wait until August for the rest of the rock to come so that I can finish it.  It's partly planted where there will be no future disturbance when I'm back to constructing.  It's terrible when you outrun your supply lines.  First, a whole day was spent cutting tufa and laying it out, so the building was really easy and thus speedy.

Really lovely Anne! Ian Christie remarked elsewhere about Ian Y's short piece on the Beechgrove Gardening programme being (an all too short) breath of fresh air for those of us who love growing alpines. I would dearly love to see a programme on your's and some of the other N. American rock gardens and nurseries. It would be like gardening programmes eventually discovering the fresh air of the mountains: 'The Land above the Trees'! (Maybe I am waxing too poetic? :))

That would make for stunning television, Tim … I could recommend at least twelve more beautiful gardens and I'm sure that Panayoti and Mike Kintgen could add a further fifty or more (both private and public) - all crying out for recognition, exposure and commendation.  With the right presenter, an in-depth analysis of the history, location, design and, most importantly, the plants of the chosen gardens this could make for ground-breaking television.  There are so many wonderful gardens (not necessarily 'alpine' in every case) in the States and Canada that this could run and run.

I've been working on a new extension to my rock garden, a little grotto of sorts for plants which require a bit of protection from the hot afternoon sun. A step became a seat,  a place to sit and enjoy the garden. By chance this flat topped rock which forms a pillar on the outside of my seat makes an excellent table for a cup of tea or coffee! Not that I have time to sit and drink tea while in the garden. Too much to do! But one can dream can't one?

I have a ton of seedlings raised from seedex seed growing nicely and I'm wondering if people can discuss the best stage of growth for planting out into the rock garden. These are destined for my crevice bed; the question is, is it better to let them grow on into strong little plants in the tubes or carefully nestle them into their ultimate home and let the establishment happen in situ? I imagine there will be advocates for both options...

Below are pictures taken today of Penstemon virens, Penstemon hallii and Erigeron compactus as examples.

Post by: Lori S. on June 25, 2015, 03:35:23 AM
Your examples, penstemons and erigerons, are both very tough customers that do well in the conditions here, so I'd have no qualms about planting them out at an early stage (as I do with everything, though, successfully or not.  ;) ).

Jamus,

I took a look at your rock work. It looks fantastic!

Be very careful with Astragalus. I keep thinking they are going to take hold and then they give up. I am going to experiment with direct seeding in the crevices. Many Astragalus seem the prefect plant for our climatic conditions. So far, for me, it is getting them established that is the main road-block to my success with them. Maybe you, or someone else, has the secret to their successful establishment in the garden?

Most here will be aware of D'Arcy and Everest the alpine nursery  (http://www.darcyeverest.co.uk)- a family run nursery, established for over 20 years growing all their own stock of unusual alpine and specialist plants. They have just been at  RHS Hampton Court  Show with this  super display of alpines, which really packed a lot into a small area and will, I hope, have given inspiration and enjoyment to all who saw it.

Post by: Tristan_He on July 27, 2015, 11:18:42 PM
Here's my effort. I recently had to relocate my rockery due to weed problems. We have finally walled and gated off the front garden properly, and as our soil is already very stony, I used a lot of material from there, as well as stone left over from some changes we made to our house a few years ago. I also reclaimed the tufa from the old rockery. I'm reasonably pleased with the result, though I think there are too many plants and it's a shame I didn't have access to machinery to move in one or two really massive boulders.

I'm a firm believer that since mountains are vertical (or at least, sloping), so should rockeries be. I also think that the rocks should be at least as prominent as the plants - unfortunately it's always tempting to add one more plant... I love to see small pieces of alpines planted in crevices that they can work their way along - they look great once they establish.

I think I will lose the Daphne 'Arnold Cihlarz' unfortunately.  :( Still, worth attempting to transplant it.

Very nice rockwork and planting, Tristan - and the wall behind is rather smart too!    8)
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Tristan_He on July 28, 2015, 02:15:51 PM
The wall is nice isn't it? Chap who works under the name of Snowdonia Walling - we've really liked his work. Shame to cover some of it with a rockery really!

I'm pleased with the overall effect too. Being able to use the local stone is a real advantage because it means I can get hold of the same stuff in different sizes. A big problem with bought in stone is that it tends to be rather evenly sized - and it's usually really hard to get smaller stones or gravel to match.

I have collected up small stones from elsewhere in the garden and added them to the rockery - these have the necessary sharp points and miscellaneous sizes which look like they have been weathered off using frost, rather than the rounded river gravels you often get in garden centres.

I've also added topsoil covered with slate chippings to the crevices on top of the coping, which creates a good environment for tougher plants like Sempervivums, Sedums and Dianthus (our native Sedum anglicum looks great there and this year was absolutely covered in white flowers - if it was an Androsace or something it would be a show winner! They are really establishing well there, though it's been a wet summer - we'll see how they cope in a drought. I also like to jam Sempervivums and things like Lewisias into crevices into stone walls, with some extra soil.

The main problem is that I always want more plants!

This rock garden reminds me of one from a few years back, posted by Geir Moen and he said it was made by backing a lorry up to the right place and having the gravel and rock simply tipped out down a slope. The garden was where the material landed. It looked  like natural scree and he was growing some fantastic plants in it. I remember Primula bella et al.

Post by: Tristan_He on July 29, 2015, 09:33:53 AM
Thanks all... I love the idea of just tipping material out of the back of a truck! I did try to give things a tad more structure than this but am limited by the size of rocks I can cart around. I have also tried to keep different rock types seperate.

The dwarf Rhodys and Salix boydii from the old rockery gave some instant height and have transplanted none the worse. I've also jammed some cuttings from these into likely spots. 

I'm very fortunate to have Aberconwy Nursery nearby which is a great source of plants. I also grow quite a bit from seed.

Primula bella looks gorgeous! Does it ever turn up in the seed exchange?

I fear the photos of Geir's construction of his garden - with lorry loads of stone that he bought for around Ł5.5  per 1000kgs - were lost with the demise of the old forum. You can see the  result growing well though, here :

I showed the construction of this covered rockery in my Ardivachar blog, but it's probably better suited here.

To recap: the base was filled with sandy soil with 20mm chippings worked into the upper surface for extra drainage. Rocks were then laid, contours and raised areas were filled with sand. The surface was treated with a thin layer of John Innes compost with 50% extra grit. As planting progresses, a top dressing of grit will be applied.

Thanks Maggi. You're quite right. I couldn't find a reliable photo of the type form, or a description.

Do you think the two pictures in your links are the same species? Hard to tell I know but the Czech one is more deltoides like. Certainly they don't look the same.

I really think we need that monograph!

Ralph's plant is a lot more compact than all the Dianthus deltoides  I have here. I mostly have the darker forms, which I prefer, but  they are all taller plants  in flower and with the foliage keeping more close to the stems.

Post by: Tristan_He on August 08, 2015, 06:29:26 PM
Hi Maggi, yes it does look more compact than deltoides usually is. But the foliage and flower shape are very similar, and it's only just coming into flower. Would be interesting to see when it's fully out.

Constructing a home for alpine plants  - cross posting this here
Film with Christoph Ruby about how one can make an alpine garden at home.
 I am very pleased to  have been sent,by Hans Joschko, this link to a short film  from German TV - it is about the construction of a garden for rock plants- a project to bring the alpine home of these plants into a private garden. The piece films Christoph Ruby ( familiar to some from his pieces for the IRG e-magazine) who is director of the Botanic Garden of Hof, making and planting a fine little crevice garden. 
It is  less than 6 minutes long and cleverly produced. Using time-lapse  we see the construction and is  you watch it a couple of times you will get the drift, even without knowing any German!

Astragalus,

Around here we sometimes call it 'Wayne's Silver', however I have heard both names used. Does it set viable seed for you? I have never seen viable seed on ours. I would certainly like to grow some F2 seedlings. Our plant has been in the ground for many years now, however no flowers yet this year. It is a late bloomer for us, but this is getting late and not even a flower bud yet.  ???

It is 40 C right now and the Epilobium varieties are still holding up for us despite very little irrigation this summer. Rain? We rarely get rain during the summer here at the lower elevations.

Thank you for sharing. I am intrigued by your variety of plants!

Robert, the Zauschneria 'Wayne's select' (which may well be 'Wayne's silver' since it has silver foliage), is just starting to bloom.  This is the first year it shows a lot of buds.  I hope to be able to collect seed this year and if I get enough, would be happy to share.  Some years we have early hard frost - hard to believe when it's so hot right now.

In the crevice garden but not in bloom - a Daphne x hendersonii simply called 'Rick Lupp' and one which he doesn't recall according to Harvey Wrightsman.  The foliage on this one is wonderful, and the growth habit quite different to my eye.  The branches lengthen and then start arching.  It would look good planted above a rock so it could spray over and down.  The bloom is typical but nice.

Photographed late this afternoon with the sun quite low.  The Astragalus utahensis is the biggest excitement, not just because it had a second bloom, which it has never done before - but also there are now 3 seed pods developing.  In all the years I've grown this, it has never made seed pods.  It has also become the largest I've ever grown.  Of course, we had no rain for 10 weeks and now after a paltry rain last week we're back into drought mode.  Can't do much in the garden because it's like dust.

Anne,

I have been busy dealing with other matters and was delighted to see your posting. The weather must not always be so conducive for the dryland Astragalus species? I guess this has been a banner year for them.

Do you grow any South American dryland species such as some of the Adesmias?

It is still like dust around here too, 32 C or more every day.  :(  I will be glad when the rainy season gets started, this should be very soon now. The forecast is for cooler weather at least.

I look forward to more photographs from your garden.

Robert, our weather has cooled a little bit, thankfully, but still no rain and the forecast is for a warm and dry autumn.  At this rate, the astragalus seed pods may have time to mature.  I'm trying to grow Junellia macrantha from Patagonia.  It's still alive after 3 years but that's all I can say.  I think the South American plants may have difficulty with our cold winters and lack of reliable snow cover.  The adesmias and  arthrophyllums and astragalus that I saw would all be high on my list of plants to try.

I remember many Adesmia (and other) species from Argentina but unfortunately I didn't find any seeds. I would love to try some in my rockery!

The first is Adesmia corymbosa, the second is A. parvifolia. The two next is quite similar to parvifolia and the last one could be corymbosa.

Trond,

Adesmia, and many others, are species worth experimenting with here in California. It is much easier for me to be proactive with California Native species right now, and there is certainly a tremendous number to work with even locally.

Thank you for sharing the photographs. More ideas beyond Chileflora.

Trond. great adesmia pictures.  All the ones I saw in Patagonia were yellow.  One was really tiny and grew at 10,000 feet along with a superb astragalus.  Our trip was between Nequen and Mendoza, very dry area for the most part.  Adesmias were everywhere. and a few were very compact (and very thorny).

From Eugen Tarasov on Facebook :
"It is an axiom that the ideas for the rocky gardens we derive from natural rock formations. The ideal scheme: saw -liked, fixed, reproduced...
But reverse the course of events, when any garden creation, erected by inspiration, later finds its counterpart in reality. It is a holiday, granting the understanding that the work was relatively faithful.

That's beautiful Maggi, a lovely natural formation and an uncanny similarity to the human formed outcrop. I encountered the misinformed prejudice against vertical rock work at an open garden recently. They had a small rock garden and I commented to the owner how I liked a particular section of it with some tall stones standing in a group. I said to him, "I like how you've positioned those stones, they feel very natural". His response took me aback; "Oh I don't know how natural it is when you start balancing stones up like that".  Huh? Do these people go around blindfolded? Or just filter what they see through their preconceived ideas of what should be?

Jupiter, there's a place in New Mexico (Cochiti  Canyon, I think), where the canyon floor is littered with black "Apache Tears" (obsidian),
and the sides of the canyon have enormous boulders of some kind of hard rock balanced upon very high rock formations ending in a very skinny point.  The lower rock is much softer and has eroded at a different rate, thus making a scene which looks quite impossible.  You're walking way at the bottom, just waiting for these huge boulders to come crashing down.  Sorry, no picture.

"Slick Rock" formations are near Moab, I believe, which is in southern Utah.  It's quite incredible, and not far from natural rock bridges formed over the years.  Weather and erosion play fantastic tricks.

I think their beauty is enhanced by the non existence or at the most minimal vegetation clothing the rock. I'd be happy to create exactly the same in our garden as a salute to the 'gods of rock' however if that was the case I'm sure my 'planting fingers ' would be very itchy ...... ;) ;D

When building a crevice garden, I am sure that you should plan it all out carefully and do it all in one go. Unfortunately, not the way I have done it.

In autumn 2014, I built a small crevice garden and showed a picture on this thread on 23rd November 2014. Then extended it and showed a picture of the extended crevice garden on 6th May 2015.

Made a further extension last autumn and I have now begun to plant up the new parts. Not much colour just now, but the Kabschia saxifrage in the older parts have lots of flower buds.
Picture of crevice garden version 3 is below.

I'll look forward to seeing it again soon Bob, when the saxifrages are in flower. I suffer a permanent state of Kabschia saxifrage deprivation as we have so few here and may not import plants.

Looks like a nice sunny day in Scotland. :)

Hi Lesley
We are lucky in Britain and seem to be able to assume that if a plant is available commercially anywhere in the world then we can buy it here.

It was a lovely day here in Stirling and after a few hours gardening, I was able to sit out in the sun. First time this year. However, from David's post I gather it was horrible weather down in Devon.

Spent the day working on my new (extension to my) crevice beds. I haven't mulched with any gravel and chippings yet but I'm happy with how it's going... I definitely think I'm getting better at it; looking back at the first and second crevice beds I like this one a lot better, and the second was better than the first, so that's progress! I'm itching to start planting!

Bob and Jamus have both made good features for alpines. If anything (I try not to criticize as I am a poor gardener) I would remove the labels. They detract from the effect. My attempt at a "rock garden" as a site for alpines was a mistake. I placed three squares of rocks in the area 12 ft. x 12 ft. and that took up too much space. Over the years the addition of small chippings as a top dressing has resulted in a "scree" instead of rocks. I mention this so that other people do not make this mistake. Does it matter that we may forget the names of plants, after all, they are there to be enjoyed. We could make a sketch with the plants on but then it becomes too much trouble to keep altering it. Well done both, I hope the gardens give many years of pleasure.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on April 04, 2016, 05:04:57 AM
A possible solution to the label issue is a nail with a number painted on the nail head.  The gardener would then have to keep a notebook of names corresponding to the numbers.  This method does have some  advantages:  the nails are  fairly easy to hide, and they are much smaller than labels.  I've seen troughs where this was done quite effectively.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Lori S. on April 04, 2016, 07:35:37 AM
Why not just draw a "map" of the trough and write the plant names on it?  Or take a photo and do the same?  No nails to be lost then.  Either is easy enough to do with a trough.

I also don't like labels sticking out and I started to do like Matt last year for a small rock area first. In a large rock garden it might be a bit more problematic though; would involve a lot of 'data keeping'.
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Tristan_He on April 04, 2016, 09:49:46 PM
I don't like labels either (they get pushed right into the soil by and large) and also tend to be in the habit of shoving pieces of things into handy crevices in the rockery. This looks nice but the result is that I have quite a few things without a label. Saxifrages and houseleeks are the worst as they often grow in places where a discreet label is hard to accomodate - so a fair few 'white flowered ?Allendale something or other' and 'sort of vaguely like paniculata but probably a hybrid encrusted thing'. I don't think I'll be applying to hold any national collections!

I have now started to keep a spreadsheet listing everything I know I am growing. Helps to narrow it down a bit at least.

I have done that for many years.  It will help if you give location names to certain areas (east garden, front yard, etc.).  Then you can narrow it quite a bit more.  For troughs I list all the plants in a single trough on one or multiple tags and put them all in one place in a discrete part if the trough. Can you find them in the pic below?

I like the map idea too and I'll be doing that. I was thinking I might overlay a grid like a street directory and then just have a list, B6 - Saxifraga paniculata, C2 - Raoulia parkii, and so on. Yes I like that idea.

We just had snow here so everything is covered up for almost the first time this winter.  A number of plants were budded due to the premature warmth in March so who knows what will happen.  All the flowers and buds on Magnolia soulangeana are shot - it happens two years out of three so it's not entirely unexpected.

I don,t know if the same applies to Magnolia but the buds and flowers of Camellia are affected if they thaw out too quickly after a frost. Planting these species where they don,t get early morning sun may prevent this. Re-siting affected plants may not be possible if they are too large.

The work materials are ready and waiting and the crevice garden has started to bloom about 3 weeks ahead of time.  The Veronica armena  seedlings put in two years ago are the first of the veronicas to bloom - usually they are the last among the veronicas.  The Western phlox are always early but are two weeks ahead of themselves, and all the daphnes are completely budded.

There is still a lot that is as lacking on line as it was in the print version - I have always found it to be  frustrating to use.   
A good point is that the sections for Dionysia has been updated online, as has, recently Primulas - by Paul Ransom and John Richards respectively.  You'd never know to  look at the site though - no proper announcement of these improvements has been made to let folk know.  :-\

Hi Kris, I didn't intend to criticise you in any way, my computer also has auto-correct and gets me into all sorts of trouble … I was simply making a (hopefully) humorous pun about the old saying; "Don't make a drama out of a crisis".

The crevice garden is starting to look very colorful.  Flowering about 3 weeks ahead for most plants, the result of the truly weird up and down temperatures, snowless winter the garden has had to endure.  Many older treasures succumbed, unfortunately.

The crevice garden is heady right now with the scent of daphnes, which are blooming well ahead of schedule, along with everything else.  Photo#3 is of daphnes that sulked for a few years and now are adjusted and bloom like crazy.  Planted 10 years ago and labels lost during their long period of sulking.

Thanks, David.  But what an amazing difference a few years makes to a crevice garden.  In 2011, the Wisley crevice garden was newly planted and very sparse although there were many plants.  Crevice gardens really seem to eat up plants even huge ones like this.  Nice to see things taking hold.

The crevice garden is just bursting now.  Penstemons have started and I've been too busy to photograph.  The convolvulus had started and it's usually prime by mid-June.  The garden is open May 21 and there will be nothing left at this rate.
People visit the garden expecting to see everything that was in a talk bloom at once, which of course it never is - but at this rate it soon will be.

I particularly liked the Astragalus detritalis Anne, such a rich colour, but can't help feeling it would finish up as little more than a pile of mush in my garden. Managed to buy a few more Daphnes from Keith Wiley at last Saturdays AGS Show in Exeter. Small plants but hopefully they will live and grow.

David, the first two are in the garden and are really good, but the D. jasminea x velenovskyi is completely new to me.  Since both are low growers it should be really interesting.  What do you know about it?  The D. jasminea 'Delphi form' is in the garden but has not yet shown that it will get through a really normal winter, i.e. very cold.

Anne, I really know very little about Daphne jasminea x velenovskyi and so far I haven't found anything on the Internet. There is no mention of it either in Robin White's book. As I said I bought it from Keith Wiley last Saturday so it is possibly a cross that Keith raised himself. Although I relabeled it when I planted it in my garden I think there was some information on the label that came with the plant. It's in the dustbin at the moment but I will rescue it tomorrow.

My new raised crevice bed/wall.
This is my very first attempt at crevice gardening and after trawling through the all the great posts on the subject here in this great Forum . . . . I decided “to have a go!” ;D
As mentioned in a previous posts, I have difficulty bending and squatting, but I can stand for hours. Although I do get backache, which mostly, I try to ignore!
The dimensions of the new bed I have built is 15ft 8inches long x 2ft 5inches wide x 2ft 5inches high. (all sizes are inner dimensions) I also have a spare adjustable computer chair which will afford me some comfort when maintaining this raised bed.
I will include a few photos for your perusal . . . But please be kind!  ::)
I have tried to create valleys and peaks and what is possible with this, is that I can put plants in sun or part shade, but of course all you good folk know this. These are all new young plants shown here. Some I have recently bought whilst others are young cuttings of my own.
I will try and keep this page updated with my progress.

This species is popularly grown in rockeries or alpine gardens; and it occasionally becomes naturalised outside of its native range, especially into crevices and rock walls.

Both Ian and I are very fond of Erinus alpinus, Franz. I think it is sometimes overlooked as not  being  rare enough - but it has a real charm to it.  We're getting some colour variation here now, thanks to some seed from a kind English friend who  gets several colours in his garden.

I have seen it covering a small hill near the cairngorms. I think it is also planted at Inchnadamph. Some people think it is alright to introduce foreign plants which then become weeds, out-competing native species.

Hmm.. introduce Erinus alpinus to your rockery at your peril, it is an enthusiastic self seeder, especially in tufa. Pretty little plant though.

Post by: Maggi Young on May 11, 2016, 09:57:34 PM
I'm at a stage in life  where the more enthusiastic self-seeders are more than welcome - but Erinus is not at all bothersome here in that respect- and any that may find their way to an unsuitable place are easily removed. 
Their flowers really repay close inspection - delightful!

Post by: astragalus on May 11, 2016, 10:54:57 PM
So glad to hear that Erinus alpinus is such a good doer and spreader and so easy for everyone.  It certainly doesn't behave that way here. I thought it was finally established (after many efforts), but it didn't make it through the dreadful up and down winter.  Maybe I should just spread the seed and see if anything happens?

Yes, Anne, I would just scatter theseed where you'd like it - it's what we  did with the coloured strain we got from Jon E.
 Jon, from much further south in the UK than us, finds it tends to  flower for him in its first year but it takes a couple of years at least to get going here.

Erinus alpinus 'Mrs. Chas. Boyle'
I have just taken this photograph. I go along with what Maggi and others say about this little charmer! I have never found it to be the pernicious weed which some claim it is; even when it pops up in a patch of Sempervivum arachnoideum, or a Kabschia Saxifraga, as it is easily removed. There is a white form, and E. a. ‘Dr. Hanelle’ has flowers of a glowing carmine. :)

I grow a wide mix of Erinus alpinus, from white through pale pinks to dark pink, but weed out the lavender ones because I don't like the colour.  I let them self-seed and simply weed out seedlings in inappropriate places.  It is very manageable, unlike the Wood Avens seedlings you can see, which are a perishing nuisance.  Let to their own devices the Erinus seedlings usually germinate in the autumn and flower the following May (at least in Southern England).

I should add that I am very glad to hear that some of this mix of colours are becoming established in Aberdeen.  I tried to send Maggi seed from the whites, but inevitably there will be a mixture, and I'm not sure they come true anyway.

I'm at a stage in life  where the more enthusiastic self-seeders are more than welcome

I'll send you a mixed packet of mine Maggi! Campanula trachelium, Meconopsis cambrica, Digitalis purpurea, Pilosella aurantiaca, Geranium endressii. Alchemilla mollis, Lunaria annua, Hesperis matronalis (I see you already have a nice dandelion!). All very nice, and all rather rapidly become too much of a good thing. Mind you we have very light soil, so seeds seem to survive very well.

Seriously, I do like Erinus. It's just that it has a penchant for self-seeding in the choicest habitats in the rockery where it competes with plants that I would rather have there. Unfortunately that includes into the tufa itself, where it can only be killed by (a) hacking into the tufa or (b) weedkiller. Would be good somewhere like a gravel garden though. I may even try scattering some seed into thin grass.

A few pictures from my own garden the other evening.

First a Tulipa batalinii which has decided it fancies life as an iris  :)

The Erinus alpinus is just coming into full bloom, so there is a rash of flowers all over the crevice garden.

Along with the Erinus, another annual, Linaria alpina, seeds itself around gently.  Normally purple and brown, in the backlit from the setting sun it looks as though there is a touch of pink in it.

Finally a view across the bottom of the crevice garden, with Pulsatilla vulgaris seedheads, Veronica gentianoides (white clone I have forgotten the name of), and Paeonia x. smouthii among others.

Aberconwy Nursery
Meadow Farm Nursery
Parnham Bungalow Plants
Craigiehall Nursery

The first three were at the AGS show in Solihull on April 16 and Craigiehall Nursery is where I have received some wonderful plants during this last week and today.

I planted up a number of them a few days after the AGS show and have been sporadically planting others since.
They are all making noticeable growth and many are flowering.

Thank you David  ;D  but I don’t deserve any credit - they more or less came out of the pots as you see them!
Admittedly, they have increased in size and buds have opened into flowers. I give credit to the nurseries for producing healthy robust plants; especially those from Craigiehall Nursery which were beautifully packed and a very good size!

It will be nice to see what they will be like this time next year when I can refer back to these posts wont it?

By the way. . . Why cant I grow Linum ‘Gemmell’s Hybrid’ like I did in the mid 1970s?
Over the past years it has never put out the abundant show of blooms it did back then. Others I have seen recently boast not much more than a dozen flowers at any one time.

This is how it grew for me 40 years ago. Sorry about the quality of the photo, it is from a 35mm slide taken on a Russian “Zenith” SLR camera.

Beats me - the darn thing has gone from here altogether.  :'(   Like yours, it used to do well.

I can't grow 'Gemmell's Hybrid now either and have lost the last two or three plants bought in recent years yet way back in the day I could grow it easily and well and found it easy from cuttings too.

Hello Anne,
I must start by saying how much I enjoy viewing the lovely pictures you post on the pages of this Forum of your Hudson River Valley garden.  :)

I know nothing of the intricacies of plant or animal breading, but browsing Google comes up with “much food for thought” about the loss of hybrid vigour.
If I understand correctly Linum X ‘Gemmell’s Hybrid’ was a cross between L. elegans and L. campanulatum by a Scottish nursery in the 1940’s.
Now, the first generation cuttings produced a good flowering plant, as did several generations afterwards. But move on 30 plus years to the 30th or 40th generation cuttings and you get the sad plant of today!
I read it is the same with some crosses of sheep, pigs, trees and other plants.
I understand little of this and would welcome a more learned and layman explanation.

Why, for example, has this not happened with Salix X boydii?  ::)

That's food for thought. Certainly this has happened here with some of the gentian hybrids, Now, after making divisions, they are planted else where in the garden in freshest mix with different neighbors. Time will tell if this helps.

A few more additions to my crevice garden.  :)

Dianthus alpinus 'Pudsey Prize' - I first bought this in the early 1990’s but it never survived with me.
I’m trying again, but this time I will give it acid conditions, as advocated by some of the eminent gurus on this Forum.

Geranium farreri - another plant which was just fleeting with me.

Mimulus cupreus 'Whitecroft Scarlet' The first time I bought this (many years ago) it did have scarlet flowers, but this shows a definite orange colour. Is it a variable plant?

Well mine (a smaller one in a trough) looked very sad after a rabbit climbed up and grazed it to surface level. Nothing was visible at all except the disturbed compost but over this autumn it has sprouted from below ground level and is growing (slowly) with multiple stems.

Hello Yann,  8)
It is many years since I have grown Mimulus, and I have only ever grow M. naiandinus and M. cupreus ‘Whitecroft Scarlet’.
They stayed with me for only two or three years. I would overwinter cuttings in a cold frame and grow them in cool, moist conditions.
Although I did do well with M. naiandinus, (which was then called ‘Andean Nymph’) by growing it with its face in full sun but with it’s feet on the north facing side of a big hypertufa rock.— That was in the mid 1970’s!

One of the most common causes of loss of vigour in specific clones is virus infection. This may or may not be visible.

Salix is naturally a much longer lived plant than Linum or Gentiana, so it's likely that it will have more defences against viruses and the things that spread them (aphids, leaf hoppers etc). As a result it may accumulate (and hence lose vigour) viruses more slowly.

and then go back to that quote you made a few posts back? (That's probably a cue for dozens of people to come tell us they have it a metre wide with ten thousand flowers!) I think there might be a glimmer of hope for us don’t you think? ;D

Amazing what lessons animals can teach you. Deer taught me that many penstemons can be severely pruned and will come back tighter and flower heavily.

Rabbits love penstemons too, the larger ones such as 'Blackbird,' 'Garnet' and their like. Pruned and grazed to the ground and yes they come away well, very bushy and flowering profusely. Some have been eaten to the roots and knocked right over but still survive when covered and stamped on.

Back from the Dolomites and into an awful heat wave. Oh, for those wonderfully cold early mornings in the mountains.  It will be in the 90s for a week with humidity, really brutal.  The crevice gardens had only one casualty. Everything seems to be surviving heat and drought pretty well. Flowering is mostly gone but there is still some leftover seed.

What growing medium do you use in your crevice garden?
At Wisley they used sand but had problems with watering.
The summers here are much warmer and there is very little rainfall (if any),So pure sand is not an option
But the winters are very wet and I cannot put a pane of glass over most of the plants
I tried several mixtures but those that are fine in summer are not in winter and vice versa
Any ideas?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Tristan_He on August 18, 2016, 09:54:06 PM
Pure sand is useless. It holds neither water or nutrients and washes out when watered.

I use a mix of gritty sand and sterilised loam. I think the best mix depends on the vertical angle of the crevice garden and the stone you are using. More vertical locations will take a higher proportion of soil, because there will always be good drainage due to the slope, and because too sandy a mix will wash out. I'm afraid I am not very precise about this though - I just mix it until it looks right. I also vary the soil depending on the plant - Primulas get quite a heavy soil for example. When planting into a vertical wall I use pure loam.

Even in areas of high winter rainfall such as here, many alpines can survive because water at the roots is flowing, not ponded (I don't exactly know why this is so important, but it seems to be - aeration perhaps?).
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: John85 on August 27, 2016, 01:28:31 PM
Thank you Tristan
I'll use slate and the stones will be vertical.
What do you think of this mixture : 1/3 grit, 1/3 sand , 1/3 loam ?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: Tristan_He on August 28, 2016, 12:28:57 AM
Depends on the size of the grit relative to the width of your crevices John. Grit can get stuck in crevices and so make it difficult to backfill them properly. This can in turn result in air pockets. Probably 50:50 soil and sand will work for most things, maybe even a lower proportion of sand. I tend to use builders sharp sand which has a mix of grain sizes, so there is still a little gritty material.

Eriogonum pulchellum (formerly E. ercium v pulchellum) is still in bloom in the crevice garden. This one looks quite different from most eriogonums. It looks almost like a tiny shrub. The flowers are whitish with a hint of pink. It reminds me of E. wrightii subscaposum, which blooms on long arching stems (but the plant is still under 1 foot), and also has white flowers.

Interesting Eriogonum, I wouldn't have said it is one, at least not from the 'distance'. The flowers are also turning reddish when fading? I really like this 'chameleonic' feature of Eriogonums.

Very nice crevice garden. I particularly like the ample bare areas of rock which are so important in a rock garden, and which I never have the restraint to maintain (because, y'know, I could fit more plants in!).

I think it could do with an extension to cover that ugly car park and tennis court though....

Incredibly, despite repeated frosts, there is still some bloom in the crevice gardens. Some of the flowers such as Astragalus utahensis are darker than normal due to the cold but as the day warms up even that changes. Just the craziest Fall ever - basically no rain, days often far warmer than normal, but still frquent frosts.
1. Astragalus utahensis
2. Phlox pungens
3. Daphne x susannae 'Anton Fahndrich'
4. Path next to crevice gardens continuing to grow.

Maggi you're right, there are pros and cons to the trees, but in our harsh climate they are overwhelmingly positive. I am pretty sure you can't imagine the intensity of the Australian summer sun, coming from Aberdeen! It is brutal. The rock garden gets 3 or 4 hours full sun in summer, in winter it's a lot more because the Gleditsia are deciduous. I didn't plant them, they were in the garden when we bought the place, but they really are ideal for the job. They cast light dappled shade, are deciduous, deep rooted and the leaves when they do drop are small and shiny and blow off the garden easily (relatively) and don't smother things. Irrigation is me with a pump connected to the rainwater tank and the hose. I love hand watering. If I don't have time I run a sprinkler for an hour.

I always thought the uppermost crevice gardens were relatively safe from deer, and they would never walk at the edge of the cliff. The rapidly melting snow meant I could finally get up there only to find the same devastation I saw farther down. They came, they ate, they left pieces of plants and their special calling cards, which I'll have to clean up. Talk about adding insult to injury! It's now obvious that covering the entire crevice garden with chicken wire in the winter is essential.  Very disheartening. The list of daphnes they ate is long. They especially like the treasures, all of the wonderful small daphnes like D. hendersonii and D. susannae. It will be a test of their recuperative powers although a couple have not a single leaf or branch end left.

I built my first crevice garden yesterday   :D .
I have read everything I could find about creating a crevice garden the last couple of months (including this whole thread) and finally have one in my own garden.
I am now planting a lot of small plants in the crevices and top dressing.

The rocks are covered in dust in the first images. The turn dark grey with rust when wet and lighter gray with rust when dry. The top dressing will be with canadian slate (also grey and a but of rust). The soil mound is loamy soil with extra sharp sand added and bewteen the crevices is a mixture for nutrient poor roofgardens with lava.

I hope my plants will love it as much as I do and am looking forward to springtime

This amazing crevice garden in progress is part of Tony Avent's garden in North Carolina. It is called the Juniper Level Crevice Garden and is made from reclaimed slabs of concrete, that have been carefully cut with a saw. To begin, it is hard to believe that this is concrete, especially in the areas where plants have been placed. Michael Peden is responsible for one part (already planted) and Kenton Seth started the second part which is being continued by Jeremy Schmidt and his crew.  This last part has great "movement", to my mind really important when building with rock. This latest part makes me think of waves curling in on a beach. Pictures in this case are better than words.
1. Close-up of "wave" of crevices.

More of this crevice work still continuing.
1. Jeremy Schmidt working on extension of crevices
2. Future extension planned on tremendously long bank, varying occasionally in height.

This is really becoming a work of art and using such a humble material, cement. Who knew cement could look like this? And this is before the softening influence of plants and weather aging.
The caveats are of course heavy material (like rock is light!!), and the need of a saw with a diamond blade. Apparently, once the first part of the cut is made it will make a clean break with a small amount of chisel work. Cant wait to see this garden finished.

David, I would assume that's correct. I've never known of any cement that didn't leach lime eventually. I think the real boon is that it's easily available from old sidewalks being torn up, old foundations. Just a brilliant way of repurposing. They have at least 40 meters more of bank to be turned into crevice gardens.

Last year in july I buildt my little alpine garden with dolomite stones, got from Allgäu.
For this I needed big technic and needed some time to find the right places for the stones.
The spaces between the stones I filled with selfmade special soil mixes for the alpine plants.
After planting I covered the soil with dolomite gravels.
The plants grow well and flowers this year good.
Next spring there grow more geophytes too.

Maggi, one thing noticeable about crevice formations in Nature - they are not overplanted. It makes it pretty easy to photograph because they are separated usually by a lot of rock. You can see a plant following the line of a crevice, making a kind of "mono-planting". And you rarely see more than half a dozen genera (and that's a lot), inhabiting the same crevice area. It always seems to be a limited habitat. Rock gardeners in general always want to grow as many plants as possible (I'm certainly in that category), but sometimes it's good to have repeats of the same plant in a given area, especially crevices, because the end result seems more natural. My opinion, lots of room for disagreement.

Fantastic rockscapes. Mother nature always does it best!

Anne: I agree that the natural crevices hold less species in general, but one needs to have a very large rock garden, like yourself, to be able to imitate them well. But is true, and most times it can be only one species scattered over a large area, especially in case of those producing seeds in large quantities.

Post by: astragalus on January 26, 2018, 02:02:30 PM
Gabriela, it's true that most of us want to imitate Nature in our rock gardens and it's also true that Nature operates on a vast scale and makes it almost impossible to imitate exactly. Our crevice gardens have to be smaller, and most of us want to plant every available inch. I do like to see multiples of the same plant following a crevice line if possible. That's the way I see it so often in Nature and I do try and do that here in certain areas here. Walking in the mountains shows us plant combinations and new crevice ideas to try and that's always challenging and fun. You might say we are in the midst of a crevice garden craze, but surely one of the main reasons for that is that so many plants do incredibly well in them.

They sure do Anne  ;D.

Here's a small river sand crevice bed completed and planted out early last year . Residing as we do in a woodland setting where good light is limited this area is one of the sunnier positions , probably receiving about 6 hours of sunlight during the height of summer .....

January 2017. Initial placement of limestone with strata lines.

[attachimg=1]

Currently 12 months on, the bed has a well established look with a wide mixture of NZ alpines such as Leucogenes ,South African bulbs including Rhodohypoxis which over time will start to take over the bed if I let them , North Americans such as Silene petersonii , European Physoplexis comosa  ,Asian Geranium farreri as well as South Americans like Calceolaria arachnoidea which unfortunately has proven to be too vigorous and will need to be removed which begs the question does anyone know whether it will take from cuttings ?.......

Dave, I'm so impressed with what you are growing in your crevice garden. Most of your treasures are plants I could only dream about. You're growing what you like and in Nature your plants grow in many different areas.  You've just illustrated why it's always a little amusing to me when visitors comment on the "naturalness" of my garden where you'll find high desert plants growing with alpines, with plants from the Himalayas, with steppe plants, with meadow plants, with plants from Turkey, with daphnes, etc.  Nothing could be more unnatural. For me they are all unified by my desire to try different plants, but I suppose a purist would find some of the combinations a little strange!!

Astragalus.... at the beginning I divided different geographical regions in my Alpinum. But since you soon reach your limits, I have planted most of the new plants together. There are only special regions where I am consistent... New Zealand comes first. ;D

More important is the location for the plants... because a private garden is not infinite... unfortunately

Thanks Thomas.

Anne I can't grow all the plants I like as there are too many species and not enough time  ;D........

It's interesting that as I walk around the numerous woodland beds looking at an almost chaotic scene ,my eye keeps returning back to the rock gardens I've created where there appears to be a sense of order ,almost a calmness .

There has been good growth in the rockeries but nothing as rampant as elsewhere in our unseasonally hot weather of the last few months and I suspect because there is a greater emphasis on scale when planting out in rock gardens ,if there was this would be noticeable.

Campanula Maie Blyth this afternoon.

Hello Anne

 Lesley gave some background on the Forum back in March 2017 which I've copied and posted below  .

" Dates are a little hazy now but we believe it was in approximately 1978, 79 or 1980, an alpine gardener from Timaru in the South Island of New Zealand and whose name was Maie Blyth, raised a batch of seed apparently from the AGS seed exchange and which reached her as Campanula morettiana. The seedlings were not that but seemed to be C. carpatica. One was selected as a compact form and Maie propagated this and eventually sold some but without a name. After a time Maie became ill and eventually died and local rock gardeners felt the plant was special and worth naming so gave it her name as a way of remembering her and the many little plants she had distributed from her tiny nursery. So Campanula 'Maie Blyth' came into being.

C. 'Maie Blyth' is cushion-like in full growth and flowers as a total cover when well grown. The texture of the flowers is thick and wax-like and each lobe has a dint or "crimp" in it which is unlike any other carpatica form."


Cheers Dave.

Trying to post pictures. Photographing with ipad and phone and have had a problem trying to download them here.    Astragalus lutosus is such a favorite of mine that it is my photo on Facebook. For the first time it has made seed pods in the garden and I collected the seed. The foliage is absolutely beautiful. Each leaf folds up on the sides and looks like it has a silver edge, very fancy.  What you are actually seeing is the edge of the silver hairs that cover the underneath of each leaf.  It's planted in the upper crevice garden which is exposed to sun all day and is one of the windiest spots in a windy garden. It has relished this dreadful summer of heat and drought. Most of our summer rainfall comes from thunderstorms, which are very hit or miss, usually miss.

This is a photo of Astragalus lutosus with seed pods forming. It continued to bloom for weeks and make seedpods at the same time. All in all, just a wonderful plant

Hi Dave,
I’ve got this campanula here, it came with a label of Campanula Royal Wave.  Got it 2013 from Edrom Nursery here. Dunno much about its origin, but it has similar habit and appearance to the one you show.

Horrible winter like everyone else. 70F in January for 5 days and then plunged to  -18F  in fewer than 36 hours!  Spring was very cold and flowering delayed.  There were some nice surprises - like Edraianthus niveus.

Toolie, Campanula 'Maie Blyth' is a lovely plant. Do you know if it has made it across the ditch? I wonder. I'd love to try it here but my garden would probably be a death sentence for the poor thing. Last summer was particularly harsh here in terms of drought and I took some losses in the rock garden.

Sorry I don't know if it is in Aussie Jamus.
While it has never set seed for me , I find it easy to propagate from spring cuttings .....
It coped well with our unseasonal dry last summer in various positions/soil mixes as well as in a sand bed.

Cheers Dave.

Spring here was cold and grey. It  kept snowing on and off, and many of my pictures are on the dark side reflecting the weather. Despite that, there were many nice plants that made it through the winter  and bloomed well, although weeks later than normal.
Lewisia 'Little Mango'

Hello astragalus, I'm delighted with some of your successes: Astragalus lutosus and Lewisia "Little Mango". This is my first trial with Lewisias. I've got about 15 of them in their pots inside my cool greenhouse. They get only bottom watering all winter inside. However I do hope to place them out at one point. I can't tell from your picture if yours are growing flat or on an incline. Is Little Mango a L.cotyledon cultivar more adapted to garden conditions?. A single specimen of Astragalus kentrophyta is slowly growing, again with only bottom watering ,inside. Although I greatly appreciate those that grow specimens and keep their plants inside all their life, I'm interested to find ways how to cultivate these in the open. Thus your successes are so valuable in my quest. My seeds are from Alplains. Thank you. Arturo

Post by: astragalus on July 19, 2018, 08:33:14 PM
Many of my seeds were also from Alplains.  Lewisia 'Little Mango' is in a trough and on a slight incline  Many (most) of the astragali grown here are planted on sloped, very deep screes. The slope is to provide extra fast drainage and the mix itself is very open and drains very fast.  I take our natural clay and roll it into marble-sized balls, which are placed in the scree below the seedlings I plant.  The mix is so lean and drains so fast that these clay marbles are meant to supply mini reservoirs of moisture for the roots. Usually the marbles will be reached the year after planting if all goes well and the plant hasn't already died.

Another nice one this Spring was Thlaspi bellidifolium.
A short time later Synthyris missurica (crossed with another synthyris, can't recall which one) came into bloom. I look forward to this one every Spring for its early bloom and deep blue.

Beautiful Synthyris missurica Ann. I love the Astragalus lutosus. I have three groups of this plant .
This particular Astragalus  in picture #1 shown here is reblooming again. The first set of flowers produced two huge pods. Unfortunately  I did not take any pictures at that time.

Post by: astragalus on July 19, 2018, 10:40:09 PM
Very nice Astragalus lutosus, Kris. I was so surprised when it made seed pods this year.  Were you able to collect ripe seed?  A. lutosus has the longest bloom period of any astragalus I've ever grown.

Post by: Rick R. on July 20, 2018, 02:17:00 AM
Your stuff is just wonderous, Ann!  All these posts that you and others display are always much appreciated.

I take our natural clay and roll it into marble-sized balls, which are placed in the scree below the seedlings I plant.

Have you ever dug a year or more later, to see what has happened to the "marbles"?  In your very free draining scree, are they still intact, or have they "dissolved" into the surrounding scree?

I don't recall you posting Astragalus barbatus.  (I could be wrong.)  Do you grow it?
Title: Re: Crevice Gardening ......in defence of rock.....
Post by: astragalus on July 20, 2018, 01:59:24 PM
Rick, I don't know Astragalus barbatus and have never grown it. Do you have a picture? Do you grow it?  The only time I would dig in the screes would be to remove or replace a dead plant.  The scree mix is so lean that if you dumped a bucket of water all at once there would be no puddle, even monentarily. The marbles are made from sub soil and it's a very sticky clay. It's quite possible they are still intact, I don't know.  It's also possible that they don't perform the function I had hoped, it was just an idea that seemed reasonable to try. Plants do very well in the screes during our extended summer droughts but maybe they would have anyway.

The plant produced two huge pods. One day I noticed one pod missing and immediately harvested the second one. I got 20 seeds from that.

Bjřnar Olsen has a nice pic on his old site (trillium.no), but I don't see it now on his chinesealpines.com.  It's a small one, like yours and Kris's wonderful A. lutosus, with purple flowers.  I bought seed from him, but didn't get it planted this year, so it will have to be next season.

Crevice  Garden built in British Columbia for  Dr  Hans Roemer by  Paul Spriggs

From Paul Spriggs (who has just  written a book with Kenton J. Seth about  Crevice  Gardening -which is eagerly awaited).-


"Today we built a small crevice garden for my rock gardening mentor Dr. Hans Roemer. Ive learned so much from him over the past 22 years, its the least I could do..."

[attachimg=1]
"Its hard to tell but the water  container filled to the top with water in this picture. it is quite deep.and intended to hold fish.  .....  ...i know what youre thinking... 'how is that square form 'natural'?... well I personally would have used a kidney shaped tub, but this was the shape that Hans wanted. I personally have a 'no straight lines' policy in my designs as they rarely occur in nature. the edges will be softened and hidden by planting soon. "
