A sempervivum planter: color transitions
Hey semp fans, I've had a low bowl shaped plastic container planted with 3 semps for the past 4-5 years, and it sits on the lower step of my deck year round, where I get to view it continuously. The amazing thing about semps, is to watch their foliar color transformation, and rosette transformations through the months.
The 3 plants are:
Sempervivum ciliosum var. borisii - upper left, one of the best ever species.
Jovibarba heuffelii 'Torrid Zone' - upper right, a superb descriptively named Bill Nixon hybrid.
Sempervivum 'Nouveau Pastel' - a 1956 hybrid from Nicholas Moore, one of the most unique, a true semp chameleon.
For the winter, the semps "hunker down" and retreat into a compressed winter mode, showing lots of dried remains of past leaves acting as a "ruff" around each rosette. In spring they grow out of the winter mode and start expanding, taking on vivid colors. In Photo 1, the rosettes still show old dead leaves around each rosette. Just a few days later, with abnormal heat and sun here in New England spring 2010, suddenly the rosettes awaken and start taking on some color and rosette expansion (photo 2). Photo 3 shows strong coloring and rosette growth, the amazing chameleon S. 'Nouveau Pastel' is a luscious toffee color, and 'Torrid Zone' is... hot torrid red with inviting green centers. Photo 3a is a side view showing that 'Nouveau Pastel' is one of those semps that forms tall one-sided "reaching" rosettes... 'Torrid Zone' also reaches upwards. In photo 4 taken the end of July, we arrive at the color apex, with some flowering happening (thank goodness not much though)... 'Torrid Zone' is hotter red than ever after losing the cool green center, and 'Nouveau Pastel' is getting so crowded that it accentuates coffee brown centers.
Some semp species and hybrids put out "chicks" on long stolons, and this can be difficult to deal with. These three semp/jovs were selected because of their dense clumping habit with chicks close to the parent.

Mark,
a nice potful and a interesting picture sequence showing the change in growth and color differences!
I have a few sempervivium hybrids, very hardy and modest growers, bought at the local garden centers.
But I can't give cv. names to them as it was not mentioned on the labels.
Maybe you like the link http://www.semper-vivum.de/sempervivum (http://www.semper-vivum.de/sempervivum)
-
nice planter and plants, mark--the toffee colour is really great!
unfortunately, while they are hardy here, they are not hardy in small/shallow pots--as i learned the hard way the previous winter--losing several plants in a 14inch square deep pot!
i was lucky to get a number of nice species and cultivars from europe last year, all still small and in pots (sunk in the soil over winter, i think they are mostly ok, but just thawing, so its soon to tell)..
this year, hopefully i will be able to get them in the ground this year--maybe a raised bed in front of the house, so i can watch them through the year as well...

Armin - darn! I just lost two hours time looking at each and every Semp hybrid and species on the German Sempervivum site, instead of working outside ;D Judging from some of the gorgeous colors and forms, Germany is one of the semp hybridization hot spots. Using Google translate, I'm not sure the translations are very good, so couldn't determine if they ship overseas (outside the EU). Some of those orange and yellowish tones ones are delectable, as are the sombre dark ones.
Cohan - I have lost some in pots or above ground planters too, I think some are not as hardy as others, or more sensative to winter moisture. And, I think semps benefit from a more consistent level of temperature and moisture which is easier to achieve in the ground rather than in a planter. Do look at the link Armin provided (it is useful to use Google Translate feature if you don't read German), and feast you eyes on the 300+ cultivars and hybrids. :o

Hi Mark and other Sempervivum enthusiasts,
I'm pleased you started this thread and am surprised there hasn't been one before.
I have a small collection some in the garden and others in pots and the plantpot saucers that the S. 'Lion King' in the photo posted on the Edinburgh and Lothians Show thread is growing in.
I drill as many 10mm holes as I dare in the bottom and then cover these with a weed suppressant membrane to stop them blocking. Next is a layer of pea sized gravel and then the compost. JI No.2, grit sand and grit. I don't know the quantities I just know when it looks right. The single rosette was planted and the sandstone slabs were placed on the top. As the 'chickens' developed the stolons were directed to where I wanted them to go or they were nipped off and planted where I wanted them. This is nearly a year old now. I think the 'hen' is going to flower this year which will be a nuisance for something with such a large rosette that will then die. I hate it when they do that!!!
I will post some photos over the next few days and weeks as I get the time and they fully wake up.
To be going on with here is a photo of S. 'Hey Hey' in the garden that I have on file.

Hi Graham, glad that you and other semp fanciers are here to participate on this topic. My understanding is, you are also responsible for the marvelous pan of S. ciliosum var. galicicum... spectacular, looks like a Rebutia or Mammillaria. It's been requested in the "Edinburgh and the Lothians show 2010" thread that you keep us posted when your S. ciliosum galicicum flowers... judging from how many are starting to elongate in that pan, you're going to have a bumper crop of flowering, not that you want that, but even so, it'll be a mass of yellow flowers. Does it normally have lots of flowering rosettes? Thanks for giving details how you grow your plants.
The Jovibarba heuffelii 'Torrid Zone' is one of Bill Nixon's hybrids, among the best and brightest of the heuffs. Mr. Nixon lives about a 1-hour drive from here, also in Massachusetts, USA. He was very active in the days of much Semp fancy (1960s-80s), with the likes of David Ford, Peter Mitchell, Ed Skrocki, and many others, and he published the Sempervivum Fanciers Association Newsletter.
Here's another of Bill Nixon's hybrids (or at least I think it his), Jovibarba heuffelii 'Gold Bug'. It's rather slow growing, and never bulks up too well, and the yellow red-tipped color is short-lived in spring. I still have it, almost fully encased in moss, must get it replanted tomorrow in a better scenario. In my photo, ignore the terrible whitish gravel. :-X
And hey, Hey Hey looks great growing in the rocks as you have it. :D

So what makes a Sempervivum a Sempervivum and a Jovibarba a Jovibarba? ???

distinction is by floral characters, and species do not hybridise across the line, despite sharing habitat; those comments are very briefly taken from the below link-
here's a discussion of the somewhat controversial subject--the species which should be separated are clear enough, but the larger validity of the separation is debatable:

Hi Mark,
Unfortunately the S. ciliosum var. galicicum isn't mine, but I wish it was. Gail posted it as being at the London show the previous week.
Graham

Thanks Cohan. :)

If I could only grow one Sempervivum, it would probably be S. ciliosum var. borisii. It grows ultra tight and hummocky, and always fresh looking. In late fall and winter, the low flat-topped rosettes are densely packed, and those ciliate tufts at the end of each leaf make little points of light on the rosettes. The first photo is taken in mid October, and I think I like it best in its winter guise. Depending on conditions, spring color can take on rich pink coloration.
The second photo shows the plant in mid June, where the rosettes open up and the silver frosting of cilia catches sunlight to make the rosettes glimmer. So far as sempervivum blooms go, some are tall and awkward, weirdly interesting, or ugly depending on your take on such things. But with S. ciliosum, the flowers are held in more compact heads and are an appealing chartreuse yellow color. Since the flowering rosette dies after flowering, this species fortunately rarely flowers, so no worries about overly abundant flowering to ruin an otherwise fine semp clump.

this is a favourite of mine, as well--i have what i presume is this, bought unnamed locally a couple of years ago--it was the one semp that survived the 14" square pot i mentioned, (winter 08/09); when i got it (presumably grown in milder british columbia and sold here) it was quite open in form, and began to close up tightly in autumn--but, my climate being much harsher than yours--it has remained in that closed up state since, all through last summer, even though it grew considerably, the rosettes have stayed small and dense and tightly shut; it seems fine again after another winter, and spring which has seen days to at least 14C (likely higher where it is in front of the house) as well as lows recently to -10 to -15C; back up to +16 days in a couple.....
-
We seem to like Sempervivum ciliosum var. borisii. It is one of my favourites also.
Planted last spring. It sent out lots of stolons hence the large number of small rosettes. I'm not too sure its going to do too well in this situation but will leave it a little longer.
I think its going to flower.
I thought I would add S. 'Lion King' to this thread so it is easily available for those coming new to the thread.

Sempervivum 'Lion King'
Graham
-
Cohan - do you have any photos of your S. ciliosum var. borisii? If you're unsure of the identity, post a photo and we can take a look. :)
Graham - I really like the way you pot up your semps, your new stratified shale type planting on ciliosum var. borisii should look great in a year or two when it fills out. You've inspired me to do a new planting, using two yellowish ones, S. 'More Honey', a 1980 Ed Skrocki hybrid that is an orangish-reddish color, and Jovibarba heuffelii 'Gold Bug'. Need to find some good rocks with lichens.
Good to see Lion King again, here photographed with more light (not in a show hall).

John, a FANTASTIC collection there, and nicely planted in large enough pots. The problem with my collection, when I had it, was that I used small pots, eventually detrimental to the plants and the collection, particularly when those semps with long stolons reach out and root chicks into nearby pots ::)
Have you considered joining Semperholics Anonymous ;D Thanks for sharing all these. Your semp trough is beautifully planted too. I'm getting more inspired by the minute. :D :D

Mark - Even with this size pot we have to transplant them every two years which is a nuisance. They get so jammed they are impossible to water. Cleaning up the dead leaves is a days job when repotting. What is puzzling is that they can live for years and look healthy in a hole in the foundation of the house but peter out in pots if not refreshened ever two years. Maybe our mix is to fault, someone said pure loam & grit and no peat. ???
johnw
-
John, I use John Innes compost plus grit. I never add any peat in the mix (albeit the JI compost will contain a little peat or peat substitute) for three reasons. 1) I don't think they need it, 2) it is more attractive to Vine Weevils and 3) you're less likely to get moss growing in among the rosettes which is almost impossible to get rid of. I find they thrive best in a mix of about 50/50, too little compost/soil and they seem to sulk!
A couple of pictures attached to show the results. The first is S. ciliosum v borisii and the second shows S. ciliosum Pestani, S. calcareum and S arachnoideum.
-
John - rhodo-galantho-etc-phile; you should add in semps also.
These are amazing. I think it would be easy to collect as many as you if only I had the space!
The trough looks great not sure why it needs an overhaul.
And yet another S. ciliosum v borisii, in Martins post. It really is a popular good looking semp.
Vine weevils are a nuisance. There is no sign until the rosette just falls apart or blows away in the wind. I have tried both Provado and Nemasys but still manage to lose them occasionally. Anyone have any other suggestions.
The UK National Collections of Sempervivum, Jovibarba and Rosularia, can be found at www.fernwood-nursery.co.uk
Graham
-
Martin - Thanks for the tips, I'm going to eliminate the peat as moss is indeed a horror to get rid of but I think it will be still necessary to apply Provado as weevils are usually rampant here. Having said that a late July application of nematodes for weevils has decreased damage on in ground plants especially Ericaceae.
Graham - We too are out of space. The big low trough is running out of steam as the peaty soil is at least 15 years old. In its prime it was chock full of semps between each horizontal sheet of rock. You may spy rhododendron and evergreen azalea seedlings which need to come out.
Dare I look at the Fernwood site?

more nice semps!
john--great collection! but, peat?? anything potted in peat needs to be constantly repotted since the awful stuff turns into mud bricks in no time, hate it! if you want something to lighten the texture, have you tried coir? doesn't break down, or rather, not in any short term.... i don't know about keeping semps in pots long term, though, have never done it..
mark--i have old pics of the plant, and will be taking updates soon, it looks happier this spring than last, quite different winter; i tend not to think about ids for mass market plants, anymore, i just assume they are all muddled garden hybrids/open pollinated etc, and thus not truly namable (i have lots of unnamed haworthia and gasteria, for example), though i suppose semps might be safer if propagated vegetatively....

Cohan - Here peat mixed with anything organic or soil turns to black soup in time. We are using coir in mixes for other things but still use some peat but those plants get in the ground rather soon. Friends in Denmark grow many things in pure peat and as long as they use inorganic fertilizers the peat doesn't break down. They make sure their peat block walls are separated from the lawn or any soil or compost by a barrier of sand. They grow incredible plants, I was stunned to see their Lewisia tweedyi in the peat walls!

Armin: thanks for the language help on the German semp web site. If I find a job or win the lottery, I'll be ordering ;D
Gail: thanks for identifying who showed that terrific pan of S. ciliosum var. galicicum
Finally found two photos of my semps, back in the year 2001, seen growing in pots woefully too small for long-term, but the intent was to create new garden beds for my 200 semps in the shorter term, but this never happened, most of the plants slowly suffered and dwindled away over the years. The photos taken in July, show that many take on their brightest colors in midsummer.

i've never used peat outdoors, but of course virtually all commercial soil mixes in canada have peat in them, so i have had indoor plants in it--after a while it becomes almost impossible to water; several years ago, i switched all of my cacti and succulents to a loam based soil, and that involved soaking, prying, scraping and in the end removing nearly all of the roots before i could get rid of the awful stuff!(it was not mixed with anything organic in the nursery mixes); it does seem to attract mealybugs, and others mention its a big attractor to fungus gnats as well... so i avoid the stuff entirely (which means using almost no commercial soils, although i find one that i think is made with composted bark (still mixed with other things), and its only for woodland seeds-never for c+s..
i wonder what is different with the peat in denmark that it doesn't break down? just separation from anything organic?-but again, no organics in the commercial mixes i've bought indoor plants in, and certainly breaks down;
i've never used it outdoors here, though at some point i will be planting some things that may like it outdoors, and i will probably harvest a bit of peaty organic soil from my own acreage for that...

I believe one day I shall take up hybridizing sempervivums, maybe a fun hobby when I retire. Only once I tried my hand at hybridizing, here's a photo showing my cross between two species, S. zeleborii x pittonii. You can see some variation in the rosettes. Since the seed is as small as dust particles, my seedling flat was perhaps 1000 seedlings or more, the problem is how to handle picking out and growing on so many tiny seedlings. So, I took the lazy approach, and potted up 3 or 4 big clumps of seedlings, and only the strongest would survive in their fight for space and light. Not a very scientific approach, but interesting to observe the results.
Why did I pick those two species, well... because they were growing next to each other in a planter and flowering at the same time ;D
-
Cohan - The Danes I know get very coarse peat and peat blocks from Sweden. It's beautiful stuff. By the way they mulch their peat beds if they sag a bit with more peat, never bark - again because it will degrade the peat.

I have to go with Cohan on this one; one of my pet peeves are many large scale nursery growers, the ones that supply the large "box chain stores" as well as smaller commercial nurseries, is the overuse of peat-based mixes. When tipping out such plants, the root ball an inpenetrable hard lump, which will never sufficiently merge with surrounding soil, and when planting such grown plants, they invariably die. I have tried blasting off all the peat with a water stream, then plant, but only slightly imprived results, 3 out of 4 will die.
I started taking a cue from the way Darrell Probst and Karen Perkins of Garden Vision Epimediums grow their plants, using a large percentage of shredded bark mulch (usually pine of cedar, or both mixed) in addition to soil. The aeration is great, and plants are ready to grow on with great rapidity. When I pot up many items now, such as woodland plants, I use at least 50% partially decomposed pine bark mulch. As an aside, I'm imprssed with how seed will germinate directly in decomposed pine bark mulch, seems to have the right moisture retention yet with aeration.
-
Mark - No peat is probably a wise decision for your hot summer climate. Many rhodos here and imported are grown in peat and bark and refuse to send roots out. We always cut big pie-shaped wedges out of the rootball before planting. Others plant as is and blast the rootball with a very strong jet of water after planting. We use alot of well-rotted bark in our mixes but have found soil in the mix - with ericaceous plants - leads to root rot in a wet summer.
Grower friends in Ontario have eliminated peat in their rhodo mix and now go with bark & perlite. Their plants now have much stronger root systems and they've had a dramatic decrease in phytophthora.
BTW way our local peat is fine stuff, the worst grade; the best is sent to Japan. I really like coir - chunky and regular - but it's not cheap and does degrade in time in this wet climate.
Attached Danish rhodo garden - all plants in pure coarse peat. Sorry this is hardly on the Semp topic.

This one is Sempervivum 'Walcotts Variety'
The main plant filled the whole area with the offsets touching the the outer edges in the summer. It receded during the winter. This is its winter colour which changes to a blue/grey colour in the summer.
'Hen and chicks' is this an American term as I have never heard of it over here until recently. The common name in the UK is Houseleek.

Wolcott's Variety is an old cultivar, one that can be commonly found in nursery centers here in the USA. It is interesting seeing yours in winter color, as it illustrates how the winter-red coloration of many semps can be misleading... because it is the summer color for which certain cultivars are best known, and Wolcott's Variety is a lovely blue-grey as you say (with hints of pink) in summer.
While I'm not usually a fan of common names, I do like the name Hens and Chicks, as it is so whimsically descriptive of their growth cycle.
Question: I see in Maggi's links to the plant shows, that Jovibarba species are listed as Sempervivum (I spied J. sobolifera shown as Sempervivum sobolifera). What's the standing of Jovibarba as a valid genus?

Mark - This is where I could get into big trouble. The trough is so old the plants may have moved but accoring to the labels:
the upper red prolific one says Sempervivum ex Lohbrunner that Ethel Lohbrunner gave us.
the middle smokey red one S. Ritton
and the one just below those two and larger, Sempervivum reginae-amaliae.
I have to do a cross check of those in pots as there are two other labels with no plants. The third label is of a goner - a spectacular bright yellow from Rex Murfitt that never offset and finally flowered. :'(

i'm still not sure i understand the problem with moss--it doesnt seem to have hurt the plants, and i think it looks great around the plants, so what is the issue?? when i planted my big pot with semps and sedum, i planted bits of moss on purpose, though they haven't really taken off yet...lol

Coahn - If moss isn't dealt with quickly in this climate it will swamp everything. Witness my neighbor's garage roof, northside. He went on sabbatical and came back to this.

okay--it wasnt apparent in the photos that it was doing the semps any harm--just seemed to be around them and not over them or anything--soi i assume that means you have been removing it all along?
moss grows here more or less anywhere shady, including under grasses etc, and will grow to some degree in more sunny spots, but i've never had the impression that it is overwhelming any other plants;certainly in the woodlands where it is most prevalent, everything grows out of moss in much of the habitat (naturally those species are more adapted to that than alpine plants might be) ; of course this is a drier climate than yours most years; in fact we have been very dry this spring, finally getting some precip in the last couple of days, and possibly this week--we'll see if it amounts to much.. in fact i think my semps outdoors will be happy for the moisture, after i was worried about them (in sunk pots) being too soggy when the snow melted not long ago!
-
Hi,
John my first instinct on the photo was that it didn't need anything doing to it, but the photo of the garage roof sems to indicate otherwise. It is still a good looking trough though.
Some of you may have seen some photos I posted on the General Forum under Harlow Carr, (the most northerly of the four RHS Gardens), of the alpine house.
Below are some photos of the Sempervivum they have in the house.

A late return to this thread. Cohan, I photographed a couple plants in a trough that needs redoing because of moss, just salvaged a plant of Talinum 'Zoe' that stopped blooming about 5 years ago, as it is totally encapsulated in moss. I'm not a moss guy, and don't now anything about the various species, but this is a dense, hard moss that grows under fairly dry conditions. The hard moss mass is about 2" (5 cm) deep, so dense that it was a job to extract the Talinum from it. I have uploaded a photo where I have started to pull away the edge of the moss.
In another planting, the same container with three semps I've shown previously, the same hard moss has basically created a "wall" that prevents Sempervivum ciliosum var. borisii from advancing another further. As a test, I have removed a narrow barrier of moss, to see if this semp will finally expand to reach the nearby rock. Once again, removing the moss is very difficult, it literally adheres to all surfaces of whatever it touches.

looks great overall--if anything just a little empty in the front..
i'm still not sure i understand the problem with moss--it doesnt seem to have hurt the plants, and i think it looks great around the plants, so what is the issue?? when i planted my big pot with semps and sedum, i planted bits of moss on purpose, though they haven't really taken off yet...lol

very interesting, mark..i'll be watching plantings here over time to see if anything like that develops..never seen or heard of it til now... the closest i can think of is that there might be some clingy moss that grew on rocks in old overgrown parts of rock gardens..

Chris, fantastic! Growing out of tufa they look great, but the eclectic collection of earthernware pottery is truly appealing and artistic, setting off the semps effectively; inspiring new planting ideas :D. Do you protect those pots in winter? Here, they would mostly split and break over winter due to freezing/thawing conditions.
PS. really like your oncos and dryland plants (acantholimons, astragalus, etc) shown in other SRGC threads.

hi marc,

I agree with Cohan Rudi, a really lovely example of how to show off Semps and they obviously like their home in a hanging bucket 8)
-

Rudi, great plantings, I too like the rusty bucket planter. In the last photo, is the cultivar name indeed 'Shampoon' or is it 'Shampoo', never heard of either, but 'Shampoo' is an english word, so was wondering. In that cultivar, it is certainly one of the best webby semps I've seen, love the tiny white webby chicks all around.
-
Dear friends,
thank you for the friendly comments.
During the cold season I hang the pail off and place it on the floor, if you live in a colder region it is safer
to dig it into the soil until springtime comes.
The cultivar Shampon (Shampoo in your language) was raised by the bavarian nurseryman Volkmar Schara
(www.sempervivumgarten.de) and named after the stuff for washing the hairs.
In my experience I can recommend to everybody to sow out own seeds and you will be amazed by the
result. Good luck!!
-
I nearly put this in the Moan Moan Moan thread.
Just when S. 'Lion King' was starting to look its best for this year, and next year I think it would have been superb the main rosette decides to flower >:(
Under usual circumstances I would take the flowering rosette out so that the rest can bulk up and replace the flowering one as quickly as possible. I don't grow sempervivums for their flowers. But as nothing is going to replace this huge rosette for a couple of years I have decided to leave this one. I suppose I'm a litttle interested to see what it looks like and I'm sure some forumists will also like to see it. I will post a photo when it is in full bloom.

More Sempervivums

hi rudi, last photo on the left side, is this townsendia ?

As if Sempervivum 'Oddity' wasn't peculiar enough already, a rosette that appears to lack the normal complement of chlorophyll has appeared this year.

Wow, that's freaky. If Sempervivum 'Oddity' wasn't odd enough (a hollow-tube-leafed manifestation), you have this weird chlorophyll-challenged variegate show up. Such things have shown up in the past in Sempervivum, and many such mutations were found to be very weak growing.

Chris,
the plant is Aurinia rupestris, a Brassicaceae.

During a short visit to the Ligurian Alps we saw beautiful clumps of Sempervivum arachnoideum,
but a very sad view were these with Endophyllum sempervivii infested plants.
-
Very interesting to see photos of the rust fungus Endophyllum sempervivii on the poor plants, Rudi.... I am lucky never to have seen this fungal infection in real life.... and I hope to keep it that way :-X
The plant becomes quite unrecognisable with the fungus distorting it :(

2 more Semps and a Jovibarba:
-
Great photos of your Semps on lava tufa, Chris, they nestle very happily there and the colours and forms show up really well 8)
-
Rudi, lovely Semps you are growing - how big is Baby Boo? Is the Jovibarba Hardy?
-
Robin,thanks for your friendly comment. Baby Boo is a small to medium sized S. arachnoideum
form. (10 mm or more)
All the Jovibarba heuffeli and Hybrids are totally hardy with me, the Hybrid in the picture originates
from a plant friend who lives in the Bayrischer Wald (Bavarian Forest), one of the coldest regions
in Germany.

thanks a lot, robin...

Sempervivum 'Lion King' with it's 35cm flower spike.
I'm sure that some will disagree with me but as I said previously; this is a waste of a good plant. :'( I do not see any attraction in the flower head, and from tomorrow when I destroy the blessed thing I will have a large gap in the pot. :(

Graham
I agree with you Graham, many semps in flower are not overly attractive, just kind of chunky and weird looking. Although, some are actually pleasant in flower, like arachnoideum forms such as 'Shampoo' shown above, and I sort of like S. ciliosum in flower. I have a single Jovibarba heuffelii 'Torrid Zone' rosette starting to flower, fortunately none of the three in this container ever want to bloom much (ciliosum var. borisii & 'Nouveau Pastel' are the other two). Here's a photo taken moments ago... don't let the photo taken during a brief moment of cloudiness fool you, it's HOT today, about 90 F (+ 32 C), supposed to be in the 90s F all week.
I'm also showing a photo of a planter with 3 semp varieties and Opuntia humifusa in it. The most interesting semp is one called 'Alluring' shown on the left; what a metamorphosis of colors it goes through, now a vibrant amber-lime color. S. arachnoideum 'Robin' is one of the better arachnoideums (well, they're all good aren't they), this one with a distinctly orange hue to the outer leaves, and S. erythraeum is so slow growing and neat... love the subtle shades of olive-tan with hints of pink.
-
Two nice planters Mark. :)
I particularly like the R. argyrophyllum ssp nankingense in the first one.
I know what you mean about S. erythraeum being slow. I keep wondering if I got the compost mix wrong as it doesn't seem to do anything.
We've had a dreadful day today. The winds have been very strong and some very heavy showers. 32C is too hot for me. A pleasant 20C would do.

Sempervivum 'Hey Hey' in its full summer colour :)

Graham, I'm afraid this is not Hey Hey. It is more likely a S. calcareum form.
We grew S. Hey Hey many, many years commercially and looks totally different.

I'm trying to think of a suitable response that is printable. Perhaps I'll just have to use this >:( and this :-X
This has been S. 'Hey Hey' for 15 years in my garden.
Will have to add this to a long list of plants bought from reputable nurseries that aren't what they are supposed to be. If it looked even similar I could perhaps understand the mistake but it doesn't look anything like it.
Thanks Luit. ???
Graham
-
Yes, graham, it may well be a long list.... some of us have got whole library shelves of such plants!
Never mind....on the plus side that is one cracking plant you have there... fantastic colours and growing really well.
That's a good link, Luit, thank you. I like the way the website allows the changing photos.

The pain and then the pleasure. ;)
Graham
-
Don't bother Graham! You are having a wonderful Semp in your garden. These things happen all the time. And I KNOW what I'm talking about. ::) ::)
The bad thing is that it seems to become even worse, especially with older cultivars. Many younger gardeners (nurserymen) don't know them anymore :(
But there are always some specialists somewhere and through the net accessible.

Here's another page with good photos of sempervivum cultivars... with music as you browse! http://sempervivum-jovibarbas.blogspot.com/2007/09/cultivares.html
The trick with semps and jovibarbas, is to find those sites that can be considered reliable web resources. They should be fairly comprehensive and give pertinent information, such as the hybridizer, year of introduction, brief description, and several photos of plants grown exposed to the weather taken during various times of the year (greenhouse semps tend to turn green and lax, hardly looking anything like their true selves). Maggi, I'm afraid the site you gave is a bit lacking in detail and credibility, too many soft greenhouse grown semps and too many "Sempervivum no determinado" :'(
There are some resources in Germany, Japan, and elsewhere, that offer more dependable information. One I like is a German site:
http://www.semperhorst.de/Inhaltsverzeichnis%20der%20HP/Inhaltsverzeichnis.htm
The listing is extensive, typically about 3 photos per cultivar, the plants grown hard so that they show their true colors, a really good resource. I use the automatic Google translate feature on such sites.
Sempervivum 'Hey Hey' can be seen here (scroll down to find Hey Hey), as comparison to Luit's link:
http://www.semperhorst.de/Diehmor%20H/Diehmor%20H.htm
I agree with Luit, that the plant is not Hey Hey, but probably a calcareum hybrid, or even possibly a tectorum hybrid, but a really beautifully colored form it is! The grouping of this semp, shown in first photo on the left, looks like a map of South America :D Oh, and the photo parsing and enlarging mouse actions on Luit's link are rather different and interesting.
There is a very good Japanese site too, select cultivars by alphabetical listing, and there's a list of S. tectorum and calcareum cultivars, mouse over any of the thumbnail images, and a large image is shown. This mystery semp may indeed have calcareum or tectorum in it's blood line, but might not be specifically listed as such, more likely than not it will bear a cultivar name.
http://www.succulents.jp/photolist_sempervivum_index.html
-
Graham, looking at the Japanese listing of S. tectorum forms on the Japanese link I gave, your colorful semp (the not-Hey-Hey) looks something like S. tectorum from Isella or S. tectorum 'Sunset', although the the leaf tip characteristics point to calcareum.

i've read down, sorry about the name! but in any case, looks great both in the gravel and in rock crevices..
i'm not inclined to cultivars intellectually, but there really are some great colours :) i received several 'lost label' plants from europe last year, and they are looking great already, even without pedigrees man-made or 'real' so i'll just put my snobbery to the side...lol

Well, I didn't say the site was the holy grail of semp ID.... I just said it had clear photos with music..... :P

Two photos of an anomalous stemless flowering on Sempervivum 'Brock'. Inadvertently, I planted two similarly colored/named sempervivums together, S. 'Brock' & 'Bronco'. The flowering semp is 'Brock', which in spring is a dark red color, greening up in summer. The 5-6 visible rosettes just below and to the left of the flowering rosette are 'Brock', the other rosettes with darker pointed tips, is 'Bronco'.
Photos 3-5 show a rosette color time progression, and demonstrate that Alliums and semps don't mix! Allium seeds drop between the rosettes, a perfect home for seeds to germinate,ending up with visual chaos, and it is near impossible to extract bulb seedlings. The allium in this case is A. flavum ssp. tauricum.
-
I will just have to appreciate it as nameless
Graham, I think your no-name Semp is outstanding and incredibly well established in your garden - still in its 'Heyday' after 15 years so congratulations :D
-
Well who would have thought that two photos with an incorrect name would have led to all this. :)
Luit,Mark and Maggi, I really appreciate you all taking the time to discuss this and to add the websites; all of which are excellent. I will probably spend too much time browsing them this evening and the next few days, and listening to the musical one ;)
I think, like many sempervivums of unknown origins, the real name of this one will never be answered.
Cohan - my collection contains mainly species but I do have a few cultivars that I couldn't resist.
Thank you all for your positive comments on how it looks and how well it is doing.

Just made a new semp planter, this task taken not because of a design inspiration, but more from an action to salvage some good semps that were sitting and suffering in small pots that haven't been replanted in 6-7 years! The new planter is a very wide but shallow plastic (clay-emulating) dish, which is partially sunk into the ground. Six semps and one Jovibarba were planted, their colors long faded in the late summer doldrums, but I look to next spring and early summer to see the fruits of my effort. Just so you know, the conspicuous plant labels will be removed as soon as I draw a map of the planter. The stone used is native stuff unearthed whenever I dig into our so-called soil, and the stone chips are the same stone that I break up with a hammer to use as a top dressing.
The following were planted.
Refer to photo #2 (overhead view) for the following descriptions, and photo #3 for a key map:
11 o'clock - S. 'Pacific Devils Food'- nice chocolate color but a difficult grower
12 o'clock - J. heuffelii 'Gold Bug' - ooh, at its peak, a rich golden yellow with red tips, small. One of the best.
1 o'clock - hard to see, a smidgeon of S. arachnoideum 'Album', but hopefully it'll regain a foothold here.
3 o'clock - S. 'Brock' - a medium size but imposing red, it has its showy season earlier in the year.
4 o'clock - S. arachnoideum 'Yukon Snow' - one of the whitest webbiest cobwebby types, nice.
6 o'clock - S. pittonii, a tight growing species with small rosettes & some dark leaf tips. Yellow flowers. Nice.
8-9 o'clock - S. 'More Honey', when at its peak of color, this yellowish amber one is excellent.
-
nice work, mark, this should look smashing in no time at all! i do envy you the stone!
i was thinking about semps today, too, took a few shots yesterday--mine are starting to tighten up already (not that most ever open up much in my climate) and ready themselves for winter, but i put together a series of one pot which holds a number of lost label plants i received last year from a grower in europe..note :this was never meant to be a 'designed' planting, just a place to grow the tiny offsets till i had a place to put them in the ground (still couldn't resist sticking in a few rocks!)--well, despite much work, i still havent finished the rock garden(s) so, the pots will very soon be sunk into the soil again..
first shot, in july of 09, shows the tiny etiolated offsets soon after arriving after a week or two in the mail!
second shot in late oct 07, pot already sunk, with some branches laid for shelter (for this and many other pots)
third shot
fourth shot 2 days ago--filled in quite a lot, eh?
these (along with 2 more smaller pots of lost labels, a large and smaller pot of named plants also received as offsets from overseas last year, and a couple purchased locally) will nearly all be going in the ground whenever i finally have a place to plant them..though i do like the look of them in pots too, so i will likely stick some bits back in pots of some sort...
don't try too hard to match individual plants between the views--i haven't got the shots aligned exactly alike (look at the rocks to orient if needed...lol);
as mentioned, these were received as lost label plants from a very serious collector, so i assume she has good reason for not attaching names to these, and i will not be attempting to name them, so no guesses needed or wished for ;)
-
Cohan, a nice succession from early planting to a fine looking pot full of semps. What I find interesting in your planter, is how each semp among the mixed cultivars is taking on good form and color, each a jewel unto itself, your selection of a prominent pink-and-pearly quartz rock fits in with that jewel effect that semps are so good at achieving.
I have an old metal wheelbarrow that I was going to dispose of, but now thinking of making a semp planter out it, the wheelbarrow parked someplace in the garden. The hard part is finding just the right spot for such a scenario, as well as anticipating what my wife will think when she sees it :P :-\

thanks, mark! i must give full credit to the plants themselves, since obviously in their tiny, pale and etiolated planting state i had little idea how they would look so i just spaced them out and grabbed a couple of pretty rocks to fill some space...lol
interstingly, i have a couple old wheelbarrows i was thinking of doing the same with! one regular size, and one tiny one that was mine when i was little, i think, and later 'used' by one of my nephews its a bit trickier for me, since i'd need to sink them for winter (i wonder if the big one would be big enough to stay exposed, but so high off the ground? or maybe i could put them in a shed over winter and see if that helps enough... might be a good experiment, but not with a whole (full size) wheelbarrow of semps in it!....
might help your wife if you show her some finished images of the fun plantings folks have done with novelty planters...lol also, i think a full sized wheelbarrow, if left on its supports-might look best in a bed of perennials or small shrubs that come up to the near/below the rim of the barrow.... and not exactly hide, but soften the wheel and supports....

Mark and Cohan,
Two nice selections.
Cohan - quite a diverse selection and bulking up quickly.

Here is the object of my next semp planting, a rusty yet still functional old wheelbarrow. While it has some cracks to provide a bit of drainage, I shall be drilling additional drainage holes. Still not sure of the landscape scenario and placement of this object d'art, but I'm working on it, and hope to find a location and get it planted in a week or so. Will upload pics once planted.

Mark, if you need some more inspiration for things out of function ;)

Cohan! I'm shocked.... of course there's no sand.... I know Vroni van Delft, she would never allow sand in the bedroom ;D ;D
( actually, I don't think that IS Luit's bed!! )

Forget the bed and the chair, just look at all those semps. :o
Its a good job the North Sea is between us.

I do like the chair and bed plantings. ;D We have an old white hospital bed here (don't ask) and I would be thrilled to find a permanent loving home for it many miles away from here. Roger won't let it go to the dump. At one stage he thought it could be usefully converted into a trolley for my nursery but it's too darned heavy apart from anything else. It's fully mobile with wheels and can be raised or lowered. It goes to the first person who will send me a private address. 8)

The bed and the Semps were taken this summer in Austria in the nursery of our young friend Christian Kress (Sarastro), who also made a year practice in our former nursery.
Therefore you will not see sandy soil ;D
The bed could have been Dutch because the double beds in Holland used (and still sold here) to be no more than 1.00 m. or 1.20 m. wide ::) ::)
These are called "twijfelaar" (transl. : doubter ) too wide for one and too narrow for two ;D ;D ;D Well understandable when you ever saw pictures of the sometimes very narrow old houses in Amsterdam.
I think I will better not tell you here about our housekeeping ::) ::) ::)
-
A bed covered with sheets of semps, cushions of jovibarbas and a blanket of plants. Beautiful! :D :D

so this is why bicycling is so popular in the netherlands--you have to stay trim enough to get in those beds..anyone who gets too large must emigrate to canada ;D
although i suppose outside of amsterdam, you are able to eat more ;)
as for the housekeeping--always good to rebel against national stereotypes ;)

Hello Cris, thanks for contributing. Your planting shows what can be done when a clay or ceramic pot breaks, it is still suitable, rustic, and visually appealing as a sempervivum planter, nice :)
I have a couple very old hypatufa troughs that I made as a teenager (embarrassed to admit, just about 40 years ago), these troughs finally starting to break apart, but portions might be suitable for sempervivum planting vignettes.

Following up on a previous posting where I declared my intent to make a semp planter out of an old rusty wheelbarrow, today I worked on this project. http://www.srgc.org.uk/smf/index.php?topic=5315.msg165794#msg165794
It will "live" in a hollowed out part of a hillside, the whole area to have sod removed (too difficult to mow the steep hillside) and the ground "sculpted" with paths and bermed planting beds. The first step was to remove sod and excavate soil at the base of the hillside up to 1' (30 cm) deep or more, to lessen the incline somewhat. The unexcavated edges around it will be broadened, and further rock features and plantings will soften the excavation. A layer of gravel will eventually be laid around the wheelbarrow setting.
1-2 Sod removed, area excavated, excavated rocks temporarily tossed into wheelbarrow. Wheelbarrow positioned.
(note: additional drainage holes were drilled in the metal well of the wheelbarrow)
3-4 Wheelbarrow heaped with sand/loam mix. The fun part, arrange native stone in pleasing formations and plant pockets.
(note: the planter is heavy, but still can be moved. However, the intent is to leave it in place.)
5-10 Wheelbarrow is planted, and top-dressed with the same rock that was hand-crushed; our native rock crushes easily with a hammer, with eye-protection of course. I like the fact when crushing the rock, one can purposely make various grades of chippings, large to small, and even some fine particles. When planting this late in the season, the semps are mostly already hunkered down and ready for winter, and only showing green, so not overly showy at the moment. Also, there are more pockets that need planting; I was running out of daylight.
When I place the rock, I like mixing rock sizes, and I try to create some noticeable height to the planter (see side view). I also like to have some rocks extend out and over the planter edge.
There will be no labels in this planter, I created a map instead. But I will also use a digital photo marked up with plant names as my guide. Some of the semp plants are ones for which the labels either disappeared or wore off.
-
Wow, Mark, what a great idea.
Who owns the copyright ;D
I also have an old wheelbarrow.... 8)
-
Super project.
I'm a little embarrassed that the two wheelbarrows in constant use here are in much worse condition than the "old" one being retired to this new purpose in McMark's project. :-\ :-[ No need to drill any holes in ours... they are worn through already! :P
-
Looks fantastic, Mark.
It looks very heavy though, I hope the legs aren't rusty, it looks like they are holding a lot of weight.

I tried to "dispose" of this wheelbarrow by disassembling it, but was handily thwarted by fasteners solidly rusted together. So then I tried my "magic sledgehammer" to beat it into submission, the wheelbarrow was too resilient to be easily pulped, so after sitting there unused in a junk heap for a couple years, getting ever more rusty, I decided to give it a new life after being inspired by creative plantings seen on this forum. :)
-
And because of the rock placements and the many crevices between rocks, you have a planting area bigger than the barrow itself. I look forward to seeing the barrow when the plants are maturing and lapping over the edges.
-
neat planting, mark! what will you do with the area immediately around the wheelbarrow?
interesting that your semps are all green now..mine are probably at their best earlier in the fall, with lots of variety in colour, now they are pretty much all red (some exceptions), but rather dull looking and a bit shrivelly... of course we have had much lower temps by now than you..

The area around the wheelbarrow semp planter will also be developed, dug out, carved, sculpted, planted... too early to say what it might look like, I generally just go with the flow, and start digging and making stuff up as I go :D I'm low low low on funds due to being unemployed, so can't buy rock or other expensive landscape materials; will need to use what's there and depend more on the plantings.
A few of my semps have gone over to a dull winter red, most of those I used for the wheelbarrow are ones that color well in spring and summer. I do have a nice clump of S. zeleborii that is a good red right now, it's going into the planter, but it'll need to dry out a bit; poured rain all day today, will be the same tomorrow.
-
looking forward to updates!
i can relate to the low funds--only working part time here, by choice, so i haven't even priced stone/gravel yet.. i have a fair amount of stone (all more or less smooth/rounded glacial deposit stuff from local fields, quartzite, granite, a bit of sandstone, etc etc)from my old rock garden and places my mom used it over the years, but i could really use some gravel/grit for top dressing and loosening the soil....

Hi
My little collection. Sempervivum species from Spain (S. cantabricum several ssp, tectorum ssp. andreanum, etc):
-
One of my favourites: Sempervivum montanum ssp. montanum from Pirineos catalanes:
-
And this is very, very special. This Sempervivum is Sempervivum sp. (S. cantabricum subsp. gredense comb. provis.).
While waiting... this plant does not have a name! Most probable being that it is a form of S. cantabricum, one will thus attach it temporarily to this one with the row of subspecies. It is inconceivable to recombine the epithet paui Fernandes-Casas, for very much reasons. It is therefore necessary to create a new denomination for this plant, for example:
S. cantabricum subsp. gredense ---
Caution, it is a combinatio provisoria which, not having been published, does not have any nomenclatural value.
-
One of my favourites: Sempervivum montanum ssp. montanum from Pirineos catalanes:
Khalid, how exciting that semp species are native to your area and you can collect various forms. I really like the dark-tipped ones with pale centers. The S. montanum rosettes are plump indeed and very glandular, attractive. As much as I love the Semp and Jovibarba hybrids cultivars, so many of the species are wonderful too, giving a good basis and better understanding with which to judge the cultivars.

Thank you very much.
In my area there are no sempers (Valencia) and is very difficult growing sempers in mediterranean weather, but I grew very much years and all is well. The sempers of my collection were purchased from a German specialist seller(Erwin Geiger). I saw very much sempers very years ago when I traveled to the Pyrenees. Is fantastic see in habitat.

That's a fine collection of Spanish sempervivums Khalid 8)
Last summer I found a nice one near Puerto de las Señales in the Cantabrian mountains (originally shown here (http://www.srgc.org.uk/smf/index.php?topic=6049.msg166997#msg166997) but reposted below). Can you say which ssp it might be?

Hello
Fantasic travel! I saw all your pics. Are excellent.
I thinh, your Sempervivum cantabricum is a Sempervivum cantabricum ssp. cantabricum.
Best wishes.

One of my favourites: Sempervivum montanum ssp. montanum from Pirineos catalanes:
Hi Khalid,
I really like this one too. Would probably add it to my small collection if I could find it in the UK.
You have a good collection there.
-
Thanks Khalid.
-
Hello Khalid!
lovely selection of semps--the new one is really nice--an excellent 'plain' form!
your semps are a little luckier than mine, just now: I measured today, and snow on my land is from 12inches/30cm to 16inches/40cm; my rock garden in progress, where pots are buried in the soil for winter, is at the low end of that;
A big pot by the house, where snow is moved off the path, is in a pile around 3 feet (nearly 1m), so almost 2 feet/60cm of snow on top of the pot..
Still nothing compared to mountain regions, but about average for us at this time of year..
-
I know that many of us find the different Sempervivium cultivars hard to resist and so I think that those of us in the UK and EU will be interested in a new (to me) web-based nursery, specialising in Semps.
The nursery is run by Andrew Whelan in Northamptonshire, who has developed his online business as a result of his private enthusism for these plants. He's breeding them, too!
There is a super selection and he offers free delivery though he can only sell to the UK and EU
That can't be bad and his prices seem perfectly reasonable.... that's always a good point, too ;D
The website is www.sempervivumnursery.co.uk
Hope you like it!

One of my favourites, Jovibarba allioni from Gorges Superieures de Cians France.. in its spring finest on May 11, this year..
[attachthumb=1]
In my cool summers so far (since '09) it has only slightly opened (though I seem to not have photos from late June to mid Aug, the warmest time; will have to watch this year), and retained red tips.. I think I have another allioni clone received unnamed, and it seems to open more... below from left: Oct 18, 2009, June 11, Aug 28, Sept 05, 2010 (overexposed, its not that pale)

Would Andrew Whelan not be the best person to assist you with this? Have you asked him?
-
Can anyone help me with the name of this Sempervivum? It was photographed at Zigana Pass (south of Trabzon, NE Turkey) in September. I suppose it must be in the Jovibarba group...
I know S. armenum, davisii and brevipetalum are species that grow in the general area, but I don't know how to separate them.
-
Hi Kees, I think it might be difficult to tell at the late season because the semps are contracting into winter mode and look very different than when in active growth.
One of the online tools that I like for Turkish flora is TÜBİVES, the Turkish Plants Data Service:
http://turkherb.ibu.edu.tr/index
I use the search function, specify sempervivum, and get a complete list of species in Turkey. Only the ones colored in blue are found in the Trabzon region.
Rosularia sempervivum subsp. sempervivum
Sempervivum armenum var. armenum
Sempervivum armenum var. insigne
Sempervivum glabrifolium
Sempervivum staintonii
Sempervivum ispartae
Sempervivum davisii (IĞDIR, ARTVİN, ERZURUM)
Sempervivum brevipetalum
Sempervivum globiferum subsp. aghricum
Sempervivum transcaucasicum
Sempervivum artvinense
Sempervivum furseorum
Sempervivum gillianii
Sempervivum pisidicum
Sempervivum brevipilum (AMASYA, KAYSERİ, SİVAS)
Sempervivum minus var. minus
Sempervivum minus var. glabrum
I don't think it is one of the Jovibarba group, because the only one in Turkey is S. globiferum ssp. aghricum in AĞRI. I'm guessing your plant is either S. armenum var. armenum or S. furseorum, but that's merely a best guess. S. davisii and brevipilum would be outside the range of Trabzon.
Sempervivum armenum (several varieties and forms):
http://www.semperhorst.de/Naturformen%20A/Naturformen%20A%20neu%20Seite1.htm
I'm not familiar with S. furseorum, here's a link with some information, scroll to near the bottom:
http://www.semperhorst.de/Naturformen%20F/Naturformen%20F%20neue%20Seite1.htm
...good photo of S. furseorum, this might be a close fit, what do you think:
http://www.treknature.com/gallery/photo250874.htm
And then I found this recent taxonomic abstract on "A taxonomic revision of the Sempervivum davisii complex (Crassulaceae)" that recommends that S. artvinense, S. brevipetalum and S. furseorum fall within the variability of S. davisii. Excerpt: Sempervivum furseorum shows minor but consistent morphological and ecological differences as well as a disjunct distribution and is therefore treated as S. davisii ssp. furseorum. Nothing is simple, is it?
http://onlinelibrary.wiley.com/doi/10.1111/j.1756-1051.2010.00974.x/abstract
-
Thanks, that helped!!! I read that S. furseorum has pubescent leaves, unlike S. armenum which is supposed to have glabrous leaves. My plants where certainly glabrous, I've zoomed in one of my pics, see in this message.
I think it will probably be Sempervivum armenum var. armenum because of the leaves and because I found it only about 35 km west from a known location of S. armenum (I found it a few km east of Zigana Pass, and it is known from Kostandagi Pass). I'm glad it isn't one of those hairy species :), which would have made it much more complicated ::). I read var. armenum is distributed in NE Turkey while var. insigne is from further west.
I read Sempervivum minus is a much smaller plant with more leaves. (S. davisii glandular hairs, brevipetalum and brevipilum both pubescent leaves)
-
To my great surprise I found out that I photographed Sempervivum armenum var. armenum a few years ago in spring at Kostandagi Gecidi (first three pics)! It does look VERY different at that time of year!!! Still I think both are armenum var. armenum.
I also discovered two more pics of Sempervivum from NE Turkey from that particular trip. These are hairy so I'm afraid they are quite a bit more complicated... Picture 4 and 5 are photographs from the road between Kars and Erzurum.
The last picture is a photograph made by Marijn van den Brink at Cirisli Geçidi, Karagöl Dağları, south of Çat. That's about halway down the north-south road between Erzurum and Bingol, probably on serpentine rock.

Back on the TÜBİVES site, there is an interactive map, click on any Province and it gives a list of all plant taxa in that province. Here are the semps found in Erzurum and Kars. "South of Çat" is still in Erzurum. I believe semps in photos 4-6 are all S. davisii, a hirsute species.

-
I think you are right! Many thanks indeed.
S. brevipetalum may have been another candidate for the plants between Kars and Erzurum, but hence this quote it is probably a synonym "Vermutlich ist diese Art [brevipetalum] in die Synonymie von S. davisii zu stellen, da nach Ansicht des Autors die morphologischen Unterschiede nicht ausreichen, sondern in die Variationsbreite
dieser Art fallen."
(Beiträge zur Taxonomie der Gattung Sempervivum L. (Crassulaceae) unter besonderer Berücksichtigung der in Kleinasien vorkommenden Sippen
Inaugural-Dissertation zur Erlangung des Doktorgrades Dr. rer. nat. des Fachbereichs Biologie und Geografie an der Universität Duisburg-Essen Campus Essen vorgelegt von Philipp Neeff aus Haan (Rheinland) April 2005)
-
Here are two other Sempervivum populations. The first is along the road Ardahan and Kars, more to the NE of any sempervivum that I have shown before in this tread. The picture is rather poor but it does display hairs, at least on the underside of the leaves. According to the publication I mentioned above this is also supposed to be Sempervivum davisii, no other species nearby.
The other picture is from Ziyaret Gecidi, a pass just west of Gurun (east of Kayseri, south of Sivas). This again is a hairy species... It may well be Sempervivum brevipilum, which is known from this general area.
-
Hmmm, no semp species are listed for Ardahan, and just S. brevipetalum is listed for Kars. I have not found a photo of brevipetalum. I did find the full reference on the S. davisii "complex" (includes S. davisii, S. artvinense, S. furseorum, and S. brevipetalum), here's the link:
http://onlinelibrary.wiley.com/doi/10.1111/j.1756-1051.2010.00974.x/full
Excerpt:
"According to the ‘Flora of Turkey’ (Muirhead 1972), S. artvinense differs from S. davisii by having green and incurved rosette leaves with stiff bristly hairs, and S. brevipetalum differs from S. davisii by having smaller rosettes, narrower leaves and shorter petals. In natural populations of the species, we observed that all the characters are overlapping, and are thus of no value for distinguishing the species. Neeff (2008) accepted S. artvinense without any comments on relationships. He recognized an “S. artvinense aggregate” from east of the Kaçkardağı, and an “S. artvinense aggregate” from south of the Karçal Dağı, and further commented on the many local forms of S. artvinense with overlapping areas. Moreover, Neeff (2008) notes that “pure forms” of S. davisii were found in close proximity to S. artvinense but at somewhat lower altitudes in the Kaçkar Dağları. Sempervivum brevipetalum was known to Neeff (2008) from the isotype only, and he regarded it as a probable synonym of S. davisii because of the minor morphological differences. According to Neeff (2008), S. brevipetalum can be regarded as a low-altitude form of S. davisii. Moreover, we could not find any specimens of S. brevipetalum in spite of many expeditions to its type location and other potential areas. This might be due to extinction of the species in the area, or the information concerning the type locality being wrong, or the species being distributed elsewhere."
At the end of that paper, brevipetalum is put in synonymy with S. davisii ssp. davisii.
The second location you mention, should still be in the Sivas Province, where only S. brevipilum is listed.
-
Thanks Mark, brand new article! Reading your paper all my S. davisii shown so far must be S. davisii ssp. davisii, based on geographical distribution :D!
The article that I referred to earlier can be found at http://deposit.ddb.de/cgi-bin/dokserv?idn=981703186&dok_var=d1&dok_ext=pdf&filename=981703186.pdf also seems to regard brevipetalum as synonymous with davisii. S. brevipetalum was known from a single location and has not been found since a long time. This article is particularly useful because it has good descriptions and detailed distribution maps :).
I just discoverd that we also found S. davisii ssp. furseorum at Soganli Gecidi in spring (about 4 years ago), there is a picture on Marijn van den Brinks website: http://photos.v-d-brink.eu/Flora-and-Fauna/Asia/Turkey-the-Northeastern-part/ (just before the Crocus aerius pics at about 1/3 of the gallery)

Seemingly I am loosing my only potgrown semp (or semplike plant). I have had it for several years and it is not frost hardy but has stood outside from early spring till late fall. This year all the rosettes started producing flower spikes and not any new rosette!
Don't know the name though!
-
I'm no expert even seeing the rosettes, (which you can't see here) but I'm thinking maybe something like Greenovia or one of the small Aeoniums, or another similar one or two I can't think of now..
Hmm, a little digging says not Greenovia- much brighter flowers, but I see some Aeoniums, such as cuneatum (no idea about foliage mat) have lax inflorescences like this..

I'm surprised when I see many species of Sempervivum on sale in which the species name or locality are not corrects. For example I have seen many times Sempervivum cantabricum ex Caballo (Spain). Totally false!
The correct location is Pico del Caballo, it is in Sierra Nevada (Granada, Spain) and in the south of Spain there is no Sempervivum than Sempervivmum minutum (no cantabricum!). I would like notify in the web where I see it, but some are copied from others and in the end is a long list of sites. This happens with many Sempervivum for sale from Spain... :P
-
Nice ones Khalid.
Well, I have just started with some Semps. I received in trades here in Romania, then I bought some seed mixes and now I have about 15 different kinds of seeds from a seller in Germany.
I will not attempt to ID all of them, even if the labels had names.
I just love them for what they are. Gorgeous succulents.
I want to see if I can grow them into nice colonies.
-
Very nice Khalid- esp to see the atlanticum, a less familiar sp.
fixpix- if they like your climate they should start to make nice colonies in short order- which I agree is one of the best things about semps :)
-
Hello! I'm new to the site and to the forum as of today! I'm a bit of a semp-aholic by my own admission. I've recently moved house so many of my semps had to come out of their comfy beds and were hastily potted up. This combined with such wet weather has meant that many of mine are feeling a bit sorry for them selves at the moment - bring on a nice spring to cheer them up please!
As I say, I've just moved so my plants still need a bit of sorting out, but here are some of my semps. I've just bought two new troughs so I'm hoping to get many of the individually potted semps settled into them very soon.

Welcome Eviesmummy - your semps are looking happy enough right now in their temporary homes- can't say the same for the poor cat trying so hard to find a sunny spot in which to snooze!

Can't imagine why you wouldn't be able to. They are very easy and accommodating plants and don't need any special conditions or treatment in these parts... the only thing they can't take is too much sogginess.
