As we have the following threads:-
Bearded Irises-2012
Oncos-2012
Regelias-2012
Junos-2012
Reticulate Irises-2012
the only gap appears to be for the Non-Bearded species and cultivars, hence my starting this thread.
My Dutch Irises are about three weeks later than they were last year and I've lost quite a few in my quest to have a garden fence that won't blow down at the first zephyr- like puff of wind. The fencing chap must have had feet like barges! So here's a couple I have left that the weather will surely ruin if I don't picture them now.
-
Dutch Iris, Eye Of The Tiger
-
Very nice that one Michael, I must look out for it.
-
Pacific Coast Hybrid Iris
-
Michael, I've never tried them but I read somewhere they needed acid soil. Have you found that?
-
No David, my soil is all limestone and I haven't added anything but more stones, (Pea shingle) for drainage. Burn the books ;D
I can send you some bits in the Autumn to try if you like.
-
Michael, will PM you.
-
They do however, like a humusy soil and good drainage.
-
Thanks Lesley.

Grown from seed (SRGC Seed Ex. 08/9-1998) sown 10 September 2009 and flowering for the first time Iris prismatica I have no previous experience of this species, does it look right?
-
Open to correction here David but I don't think it is prismatica which should have long, thin upright foliage to 70cms high (according to Mathew) and which bends over. I think it should be a deeper, purer purple or blue/violet colour. Yours from both the flower form and the foliage looks like one of the thousands of Pacific Coast hybrids. Nice though, pretty colour. Mathew says prismatica is easy in the UK but the couple of times I've had it (from seed) it has died quite quickly. A friend a little north of here grows it well and also has the white form Mathew mentions.
Iris prismatica comes from the eastern seaboard of North America, from Nova Scotia south so maybe JW knows it in the wild. I can't find a picture of it though Google will produce something I suppose.
Edit: Oh yes, it does. Heaps of pictures and information. A really nice iris but NOT yours.
-
Thanks Lesley, I looked in Mathew and was fairtly certain mine wasn't right and you've confirmed it.
-
A couple in flower today.
1. Iris Holden Clough
2. Iris Broadleigh Rose
-
In 2007 I made a sowing of Iris sintenisii from Exchange seed. I got good germination and potted them on annually before planting out around seven plants in a bed I created particularly for species irises in 2009. They did rather well and below is a picture of a group of them and a close up last year.
They did so well that they took over a somewhat larger portion of the bed than I had anticipated. As they came back into life this year I noticed that a couple of large dandelions had thrived in the middle of the clump (There are a couple of grassed amenity areas near me absolutely full of dandelions and I get a lot of trouble from seedlings) as had a creeping weed that looks much like an oxalis of some kind.
I couldn't let them go on like that so about three weeks ago I decided to clean them up and split them up (yes, I know, not the right time of year!). Result: I've lost the lot.
If anyone has a spare plant at the right time of year I'd be very happy to refund postage and package costs and if anyone has spare seed I'd be happy for some of that too.

Yesterday in the garden.
1. Iris Hollandica 'Eye of the Tiger'
2. Iris siberica 'Hoar Edge'
-
David i have babies from your seed if you would like some back:)
Dave, will PM you.

A few from the garden today:-
Iris sibirica 'Perry's Blue'-I think as the label has gone walkabout.
I. sibirica 'Sparkling Rose'
I. pseudacorus-that surprisingly seems to thrive in one of the driest parts of my garden
I. graminea
-
A PC i was given last year and Iris tectorum grown from SRGC Seedex.

A PC i was given last year
I think this is Broadleigh Edith or else Broadleigh Sybol (not sure of the spelling). I get the two varieties mixed up but both are 'good doers'
-
I got some Broadleigh PCIs from CS when she visited Aberdeen for a talk to the Friends of the Cruickshank Botanic Garden some years ago.... they all died.
I think Roma got some too... I think hers are okay....... :-X
-
a familiar story Maggie, the two names I mention are tough though. Moving PCIs is best done in grey miserable automn weather with lots of rain and lots of loose, coarse, garden compost. Small bare root pieces are very difficult to establish in more arid conditions as there is a limited window of opportunity due to their having a short root growing season
-
On Monday, my wife Karen and I went on an expedition into the Jemez Mountains in the Santa Fe National Forest to see Iris missouriensis in bloom in its habitat. It was amazing wildspread and diverse in this area. The photographs are from a spot 3250 meters in altitude. It grows in damp meadows in the midst of fir/spruce forest. The spot is perhaps 50 km from our home as the crow flies, but time-consuming to get to over rocky forest roads.
The first photo is a scenic view of Cerro Pedernal with Abiquiu Lake off to the right.
-
These photos show the variation is form, color, and pattern among the blooms. I was quite taken to see some with almost solid blue-violet fall blades, with the usual veining hardly to be seen. All these were growing within a few hundred meters of each other.
-
Final batch of photos
-
Tom fantastic pics it's not one i grow,does it increase by stolons,on your pics there seem a lot of single fans.
-
the forms I have grow like a setosa or sibirica Davey, not such dense clumps as most garden sibiricas. Avon Bulbs were stocking it.
-
Lovely set of pics Tom, thanks for posting.
-
Delightful to see the variation in these lovely flowers, Tom. Always very instructive to see that... so often folks seem to expect a plant to have no variation at all... these habitat pictures illustrate the truth very well.
P.S. Have you thought of getting a microlight aircraft ?.... then you too, can fly as the crow!
-
I.setosa alba
-

-
I.setosa alba
Very nice Ron.
-
Some more Iris sibirica from the garden today:-
Iris sibirica 'Chartreuse Beauty'
Iris sibirica 'Outset'
Iris sibirica seedling-grown from a seed head scrounged (with permission) from a National Trust garden
-
Thats good quality scrounging, ;D ;D ;D
Very fine plants David. :)
-
I.setosa alba
What a wonderful plant, and picts too :o
-
Iris nertchinska, all seedlings without any variations
-
David lovely stuff there,love the 'Chartreuse Beauty.Ron you alba form is stunning,the dark stem white flower is really nice.
-
If anyone, like me, finds Gerhards Iris nertchinska a new one on them, I looked it up in Mathew.
Iris nertschinskia, he says, is synonymous with Iris sanguinea in Section Sibiricae, a plant of mountainous meadows, open wet plains and light deciduous woods, ocurring in south Eastern Russia from the east of lake Baikal eastwards to the Ussuri region into Korea and Japan.
-
Every reference I can find says exactly the same thing David.
But looking at Gerhards pictures, ... is it really?? ??? ???
They are beautiful, 8) 8)
-
Difficult to tell, I would have thought Ron, without seeing the leaves. Mathew says sanguinea differs from sibirica in having the leaves equal to or even longer than the unbranched flower stems!
-
Iris nertchinska, all seedlings without any variations
This is the plant I grow as Iris sibirica -"small white form", I have several seedlings which have varying amounts of colour on the hafts. glad to have a name for it, thanks Gerhard.
-
Iris 'Pacific Coast Hybrid'
-
Iris tectorum (which I got from a very friendly forumnist!)
-
Lovely Wim. I've tried it twice from Exchange seed and both times it turned out to be pseudacorus.

many thanks for correct spelling , David ! Now I know while I haven`t found a lot of information, only a Japanese description.....
I can not explain why the flowers show no variation, I´m not sure- believe the seeds come from Fritz Kummert.
-
Iris wilsonii hybrid, or something else ?
-
I.setosa arctica
An Alaskan dwarf form. The leaves reach 8cm maximum, and the tallest flower is only 18cm high.
-
Ron i have it in flower at the moment and it is a little stunner,nice pic s of it.
-
Thanks Davey, but I found it impossible to capture the true 'character' of this plant. It's so small, but in perfect proportion and the so subtle variegation just eluded my attempts to capture it, :(. Glad you enjoy growing it too, I agree a little beauty, ;D.
-
That's a real gem Ron.

Iris sibirica 'Gull's Wing'
Beautiful 8) 8)
-
I love 'em all. If I had more space I would have many more.
-
It's a little strange, because I was just looking at this plant yesterday ( in books and on the net ), and thinking how wonderful it was. And today........ ;D ;D
Lovely 8)
-
The thing is they are freely available, not particularly expensive, and are relatively easy to grow in virtually any soil or conditions. Mine grow in the same bed as most of my herbaceous stuff and the bed receives at least a couple of inches of composted horse manure each year. Seems to please them. The one thing I don't like is that at the end of the season they look very untidy but at Cothele House they cut all the growth down to a couple of inches high in early September. I haven't risked this..... yet!
-
Grown from seed Iris spuria ssp. maritima
-
The clump is pictured below.
Iris spuria ssp. maritima

David my seedlings are growing really looking forward to the flowering.

Thanks for the edit Maggi, completely forgot to add the name.
Glad they are doing well for you Dave.

Is this plant not more like Iris sibirica? branched stems, taller than the leaves, brown bract, only the blade is round more like Iris sanguinia. The Kew list also says that Iris nertschinska is a synonom of Iris sanguinia. (Brian Mathew was/ is a Kew botanist though.)
There is a blue form, much like some of the early diploid sibirica cultivars, which I found on flicker by googling the name but it is not identical. My plants are all white with some variation in the colour on the hafts, and very like Gerhards. I think that they were sown from exchange seed as I sibirica
-
I.setosa arctica
An Alaskan dwarf form. The leaves reach 8cm maximum, and the tallest flower is only 18cm high.
Here's one of my seedlings flowering Ron.

David
just seen this post,not a thread I usually read. I have a plant I collected in Turkey in 1995 you can have.
-
Cheers Ron ;D

Tony, will PM you.

I. tectorum
Grown from seed, first year flowering. I managed three plants from five seeds given, which I'm pretty pleased with. ;D
-
Very nice Ron, I've tried it twice from Exchange seed and it's turned out to be pseudacorus both times.
-
If you still need one David, I will oblige.
-
Many thanks Ron but DaveyP has obliged.

I had a sudden panic attack when I saw this, :o. We lived a few miles away from 'Sun Moon Lake' TAIWAN for 10 years, and visited regularly. How could I have missed this? Then I noted it is 'Sun Moon Lake, JAPAN. Phew!! ;D
It is very lovely Rick. Thanks.
-
I grow two forms of Iris tectorum, one in white and blue is half the size of the other which I recieved as seed labled "Burma Form". I only have the larger form in blue. I understand that the smaller form is associated mith Mr Bowles who lived at Myddelton house, London.
-
I don't believe it, ::) ::). It would appear that there isn't a Sun Moon Lake in Japan! :o :o.
I can't find reference to this species in Taiwan though. :-\
Seems the Type was from Niangniang Ding, Hubei, China. :-\
I see on a PBS thread that this selection was reportedly collected at Sun Moon Lake, Taiwan. ??? By Davidson and Lankow 2007.

Seems there is another I.tectorum, collected in Taipei, ( i assume the County and not the city, ???) by Joan Cooper, which is said to be identical to the Sun Moon Lake plants.
Checking through my Taiwan floras, I cannot find any evidence of this species being native to Taiwan. My thought is that the only plants of I.tectorum grown there are garden plants, ( usually pot grown :) ).
-
Iris verna from last week.
Was going to say it's bulking up slowly but 'bulking up' is definitely and overstatement. Increasing slowly.
-
Very nice Graham, and rarely seen I would have thought?
-
Thanks David,
From Pottertons in 2010.
Just checked and they still have it listed.
-
I have to agree with David, Graham that is superb.
-
Thanks Davey.
I rather like it myself. It's just a pity the flowers dont last long, but there was at least a succession this year.
-
Thanks Graham, that'll be yet more of the kid's inheritance going.

If Rob's not reading this and get's a run on them he might be wondering why?
Perhaps I should be his agent and get a %age of his sales.

Hope he reads that Graham, he'll break out in a cold sweat :P

Superb Brian.

Thanks Ron, for all that digging around, regarding Sun Moon Lake. That does shed a lot of light on it, albeit confusing. I'll have to see if I can talk to Joan. I haven't seen her since she sold her house and gardens (about 40 miles(64km) from here) a few years back. She must be getting quite old now.
-
That would be great Rick, I really hope we can pin the history of these plants down. My current thinking is that any plants that are there were probably introduced by the Japanese when they spent some time on Formosa ( Taiwan ).
Looking forward to seeing anything you can dig out. 8)
The National Endemic Plant Checklist of Taiwan lists only two species,
Iris formosana Ohwi, 1934
Iris nantouensis S. S. Ying, 1987 ( Sun Moon Lake is in Nantou County, but this species isn't I. tectorum Sun Moon Lake, see link below).

Only two species on Taiwan,

Grown from seed sown September 2009 and flowering for the first time- Iris clarkei
-
Beautiful 8) 8).
Congratulations David on growing this one from seed. 8) ( do you think it's pure? ).
It is often said to be easy to grow, but it seems it's rarely pictured, and uncommonly shown or discussed ;) ;)
Hope it multiplies well for you, ;D ;D
-
Thank you Ron it looks about right to me. I maybe have a spare one and if so I'll put your name on it. Can't check now as we are just about to leave to meet some friends and on Monday off to Madeira for a week. I won't forget though.
-
Thanks David. ;D ;D
I'm sure your photo will generate some comments.
Travel safe, have a lovely week away. 8)
-
....... on Monday off to Madeira for a week.
Given the weather currently, and that forecast, David, I reckon you've made a smart move there! Hope you and Maureen have a really good break.
-
And Iris setosa again from my garden.
-
Grown from seed sown September 2009 and flowering for the first time- Iris clarkei
Stunning iris David
-
Grown from seed sown September 2009 and flowering for the first time- Iris clarkei
NOT! Now David, you know very well that I. clarkei has a typical butterfly-shaped patch on the falls. I'd suggest yours is an interesting sibirica group hybrid. I can't see much of clarkei in it though (also sibirica group).
I may well be wrong but I understand that I. tectorum though widely known as the Japanese roof iris is, in fact of Chinese origin, taken to Japan at some stage for cultivated purposes. The blue form that Rick L shows is the typical form we have here, along with even more beautiful pure white, I. t. album which happily comes true from seed.
-
Lesley,
very beautiful, I. clarkei :o 8) 8) 8)
-
Iris sibirica 'Silver Edge' At its best just now. Not sure about tomorrow - the weather forecast isn't good - strong winds and rain.
-
First time flowering raised from seed,it came from a bag of mixed iris seed,so no name sorry.

-
Grown from seed sown September 2009 and flowering for the first time- Iris clarkei
Easy to solve, I believe. If the flower stem is solid then is I. clarkei, if hollow then not.

WOW nice fact Ron and one intend to pinch from you and use on uninformed people :) .
-
Its a feature unique within the series Sibericae I believe, and unusually one that is easy to check.
Educate away Davey, ;D ;D ;D.
-
Grown from seed sown September 2009 and flowering for the first time- Iris clarkei
This looks like some I have, grown from wild seed. Edrom stocked such a plant, at one time with the wrong name but they had retained the collection number. I doubt that it is pure clarkii though - have you snapped a stem yet? intermediates between species are said to occur - by some.

(http://i964.photobucket.com/albums/ae121/davep1970/030-1.jpg)
I think that this is Iris ruthenica, there are several forms ( possiably varieties or species such as I ruthenica nana, Iris uniflora..)
-

Peter i have said it before and i will say it again,Thank you.This one stands about 10 inches high.
-
Peter i have said it before and i will say it again,Thank you.This one stands about 10 inches high.Did the innominata i sent you flower?
-
About 15 flowers Davey, and growing well. It is much bigger than my other one which i showed last year. sorry but I have been unable to keep up with pictures this year.
The seeds on I ruthenica are quite distinctive if you get any. Supposed to be sticky and from memory, though I don't get many, round, black and hard, the size of a small pea. Very similar, in fact, to the seeds of Iris anguifuga....related???
-
I think it's I. ruthenica too, in a particularly attractive form. The colouring and the markings are very good. I only had seed on my 'nana' form once and I remember them as being in ribbed pods, but memory may be at fault. It was at least 10 years ago.
-
Easy to solve, I believe. If the flower stem is solid then is I. clarkei, if hollow then not.
It's hollow. ???
-
:( :( Well that's one species crossed off the list. Only ??? ::) to go.
Still a very nice plant though, ;) Have we ruled out I bulleyana ?
-
I'm not sure at all Ron. Lesley seems to think my plant is a Sib. hybrid. PeterT seems to favour an intermediate between species; and as far as bulleyana is concerned Brian Mathew says "This is a plant of somewhat dubious origin and it seems it is a hybrid of I. forrestii and I chrysographes................."
Maybe I should name it (isn't that what Nurserymen do! ;D ) would Iris 'Ihaventaclue' suit?
-
would Iris 'Ihaventaclue' suit?
I have a whole collection of that species David, ;D ;D
I think the comment from Mathew is maybe true for the time it was written. I think things have moved on for I. bulleyana since then, but others will know better than I. When the rain stops any chance of a few more pics??
Does this affect my dibs on any pieces? ;D
-
<<Does this affect my dibs on any pieces? >>
No, not at all Ron I have a spare with your name on it and the flower was similar to the one I posted. I'd be interested in any further thoughts Peter has.
Will it ever stop raining- the weather does this everytime I put shade paint on my greenhouse, I just knew late May and June would be drastic.
-
Cheers David. 8)
-
A pretty poor picture but it was chucking it down and I didn't want to mess around too much-Iris lazica. The first flower since I split my clump up about 18 months ago and I don't remember it flowering this early before.

David, probably the result of enough water (at last) ;D ;D :-X
-
It only flowers in spring for me David :(
-
Probably my favorite non-bearded iris in my garden is Iris aguafugua. It is from China where it has the reputation of keeping snakes away from your yard. It sure works in my garden. As long as the foliage is present I never have snakes. The unfortunate part is the foliage dies in spring and reappears in the fall so foliage is absent when snakes would be active anyway. This iris is very winter hardy and is drought tolerant.
[attach=1]
Iris aguafugua
Iris anguifuga
-
Iris anguifuga?
-
Iris anguifuga?
My thoughts as well i thought it was lactea but i could be wrong.
-
I am sure Leon is not talking of I lactea... I think that there is just a typing error. I anguifuga is also known as "snake bane" it has interesting seeds too,- they resemble those of I ruthenica, or even Iris domestica. My I anguifuga flowers much later in spring, and the root stock resembles I tuberosa.
-
Of coarse you are right. I was trying to type the name from memory which is faulty.
-

Very nice Leon and not one i am familiar with is it related to Lactea Peter?
-
More likely to Iris ruthenica Davey, need to look it up in Jim Waddick's book - Irises of China
-
This iris is from last summer. :)
I have grown this from wild collected seed as Iris sp, possibly Iris bulleyana.
The seeds were collected in 2008 by Remi Nielsen from Yunnan, Benzilan, Beima Xue Shan, 3,463 m.
The first plant flowered last summer in the beginning of June, later than Iris sibiricas.
Do you think this looks like Iris bulleyana?
-
Happily, I have 9 pods on Iris barbatula this year. Some will be to spare of course. :D
-
Whoops, I nearly missed that Lesley, unless you have been inundated with requests if you could spare some barbatula seed I would be most grateful. I'd be utterly delirious if you could spare some decora too. I lost my last plant during last winter.
Here's Iris unguicularis and flowering this year far better than it has in the past. Although Brian Mathew says they should not be given a rich diet mine got a good thick mulch of composted farm manure during last Summer and I think it has paid off.
-
Very nice David, 8). Maybe its appreciated the extra moisture this year too? ;D
-
Yes David, of course. As it happens, no-one has asked for barbatula as yet, but it's still a way off, the pods getting fatter but still bright green. Not sure about decora as the few flowers there have been I've missed altogether and I've had to lift the plants (3) to pot them, not at the best time but needs must. If there's anything you shall have it as I have about a dozen seedlings from a couple of years ago, just germinated recently, also a few from Chadwell seed.
Here's a rather nice Japanese iris, really cool on the hot days we've had recently. I had it as 'Snow Queen' but I'm pretty sure that's not right. I have an NZIS reference somewhere I must locate.
