beautiful flowers and photos!
these are flowering outdoors already?

Superb plants and truly botanically useful photographs Gerd, a great start to Corydalis 2010.

Only the woodlanders are growing in the shadow part of my garden. All these species are growing in a coldhouse in pots (13cm).
I don`t like to see pots on the picts, so it is difficult to make good picts of small species like C. henrikii.
more picts will follow the next days.....

very nice to have an early start on the season :) its a fascinating genus, one i will be searching for--so far i have the native C aurea selfsown...

A couple of corydalis which have started to flower now
Corydalis solida from Goktepe in Turkey
Corydalis parnassica from Mt Olympus in Greece
-
Tony
Both are beautiful species and have a nice compat growth, do you grow them in full sun?
-
Oron they grow with afternoon sun, that greenhouse they are in is partly shaded until lunchtime at this time of year.
-
Thanks
-
Thay are both very fine, and compact in the flower stem. Lovely plants. :)
-
Both very nice looking. Have you tried in the open?
I still have 75cm of snow over mine.

I have a lot of solida growing in the garden no problem. I keep my plants of known provenance in pots for safety otherwise with the blackbirds and my wife's weeding a label is soon tossed aside and the identity lost.

Flowering here now in the rock garden and slowly bulking up- Corydalis henrikii
-
Corydalis are -indeed- wonderful plants!
I think that everyone who has bought Liden/Zetterlunds book "Corydalis" has admired the wonderful photos inside.
The cover alone is an artwork of it's own with the wonderful Corydalis ornata "Blue Lip" in the upper left corner!
However - my absolute favorite Corydalis is the blue/white bicolored Corydalis ussuriensis. Unfortunately only one plant is currently in cultivation at the Botanical Garden Gothenburgh. This has never set seeds or multiplied vegetatively and it has -sadly- never been accessible to the public. There are still waiting some precious little things for their introduction......

Some of them are self sterile :( so we need to introduce at least two plants of a new corydalis.

3 years ago C.maracandica set seed in what was a covered bed. This bed was restructured into an outdoor bulb bed. The seedlings remained in this bed and having been through two winters in the open the first fowers have appeared. The seed parent is certain the pollen parent is best guess bsed on colouration. Maracandica crosses with popovii, I have this cross and it looks quite different.

Yep-unfortunately!
BTW: What does it mean when Zetterlund/Liden write "maybe self-compatible to a certain degree" in their book about Corydalis ornata? Have you ever had seeds by selfing Corydalis ornata?

One flowering here today:
Corydalis solida 'Gandalf'

Flowering of corydalis has started in the rockgarden, especially in places where the sun can give some warmth.

Here are two solida's flowering in my garden today:
Corydalis solida 'Elrond' and
Corydalis solida 'George Baker'
-
Corydalis are beginning to flower with me, too. I was worried about C malkensis which is usually out in Feb. but it is flowering well now and there is even another one I didn't know I had flowering elsewhere on the scree. I suppose it self-seeded.
At last there is real colour in the garden as the snowdrops are going over - crocus, iris, scilla, hellebores, daffodils, Daphne mezereum, anemones etc.
-
We never did manage to pin a name to this one, which was bought as Corydalis species Imison Pass. This year it has its first seedlings around it.

very sweet plant--so this is the mother plant? old enough for seedlings? seems a baby itself!
-
Well, I can't compete with these beauties, but C. solida, don't know the variety, has started blooming near the Hepaticas. Other than C. lutea and C. cheilinifolius (sp?), I have no others.
Corydalis solida- unk clone

WOW, Jamie,
that's a fluo-pink one, nice.

Seedlings from solida clones often look very similar to the seed parent. This makes it very difficult to uphold a cultivar/clone name. This one looks like a seedling of one of the red forms like 'Munich Sunrise' but perhaps not a George baker seedling since GB has more narrow leaf lobes and slightly darker leaf colour. GB is also among the later flowering but that means nothing if you do not have a swarm of solidas.
My own are still under 30 cm snow but is is melting fast now.

I think this would be the mother plant and we are waiting with baited breath to see how the seedlings develop. They will either be selfed from the parent (confirming my suspicions that it is a hybrid itself) or crossed with a its nearest neighbour, which is C.henrikii. This is also quite big for this plant, but a better show than last year!
-
Göte,
thanks for the info. I did buy it as a named selection, but the label has disappeared. It was a German selection, as I recall. No seedlings as of yet.
-
Has anyone else thought that the Corydalis are looking a bit stronger coloured after the cold winter? My bed of Beth Evans is looking a lot brighter and darker. Also C. henrikii is looking darker than I remember it :-\
Susan
-
Maybe the light levels are higher later on in the year and this is what is making the difference ?
I will try and get comparison pictures this afternoon

Yes same here Susan. It's interesting to see the effects of a longer, colder winter than usual on other 'bulbs' too.
-
Corydalis malkensis starting to flower for me, and starting to self-seed nicely too!
-
I'm very fond of Corydalis malkensis.... it does spread about the place but it only grows for such a short period in the year that it can happily co-exist with umpteen other plants in the same place without doing any harm. I think a spread of it looks so soft and inviting, all foamy white flowers and soft green foliage.... like a nice bed to lie on!
-
I'm spitting tacks at present as my parcel from Marcus Harvey arrived this morning (includes Colchicum luteum and C. chrys. 'Sunspot') but MAF have removed 3 bulbs of Corydalis solida 'Nymphenburg' which I did order but can't have checked the Bio Index because I now find they need a permit to import and subsequent quarantine for 12 months Level 2 quarantine). I must have assumed that as seed was OK, the bulbs would be permitted under Level I quarantine which is basically none at all except inspection on arrival etc. as for the crocuses, narcissus et al. So I can apply for a permit ($105) plus quarantine costs or I can have them returned for which they want $42.95 (only cost $10 to send the whole parcel from Australia) or I can have them destroyed. Hence the tacks. Still thinking about it, but steam coming from ears. >:( >:( >:(

Lesley does not sound much different to here,persecute those who try to do things correctly.
Here are two Corydalis solida.
the first is a mixed pot from seedlings dug out of the plunge and the second is from Greece. I do wonder why so many of these things are named when sowing random seeds produces lots of 'named forms' and then they just multiply

Tony, I agree with the C. solida seedlings, I get all sorts of colors, the "Baker" reds and such. Your white Grecian form of solida is special, such clarity of color and strong form.
-

Yes, it is lovely...and if it were to be distributed, but not given a name, how would anyone know what/which it is?
And when two or more folk who come into possesion of this unamed plant each decide to name it, or put it up to Joint Rock ( who will ask that it be given a name if an award is made) ... what then? Galloping confusion, that's what! Which is why so many plants are given names by their raiser/finder! ;)
As an example, Ian's hybrid Corydalis x Craigton Blue has only ever leeft this garden as Craigton Blue.... it is now available in umpteen nurseries across Europe, everyone knows what the plant is and where it came from; hasn't earned Ian a penny from that commercial success, but the identity of the plant is known and , we hope, assured!
-
I'm very excited to show this picture of my Corydalis popovii. I wasn't sure if it was going to make it through the winter in the garden, as I only bought it last Autumn. This is my leap from Corydalis solidas! Jane
-
Nice leap Jane.
-
Maggi I was feeling particularly irritable this afternoon(and perhaps still am) but that does not change the situation as to lots of plants. The one you mention is able to be propagated in reasonable numbers and remain true. Lots of the bulbs are just raised from seed. As to the joint rock I have never seen any purpose in its existence.
-
Bravo Jane for trying it outside, did it have a cloche or has it survived all on its own?
True Maggi, but I'm sure a whimsical name can help sales! ;)

Hi Tony,
Too true, they self sow quite happily here along with most of the other species, may end up with a hybrid swarm!

Lovely selection Chris and I do like the idea of plants that return from the dead - it's usually only couch grass and ground elder that do that for me unfortunately!
-
LOL, too true Gail. This was the chionophila. I bought if from an AGS show at St.Chads, it was 50p sized, over the next 7 years it grew to fist size, last year it never flowered. I checked and only found a papery husk where once it had been. Two days ago spotted this roughly where the old tuber had been. It has spent the whole winter exposed to the elements, no cover,no protection, I must be braver and put my Leonticoides section corydalis outside.
Inspired by your malkensis I checked round the base of mine and found seedlings, I guess we can look forward to Maggis promise of drifts of malkensis, ummmm cultivar name there eh, 'Maggi's Drift'!? ;) ;)

Chris, the C. chionophila is exquisite... the others nice too, but that one really "sends me", as do most of the Leonticoides section. My C. malkensis is starting to seed around too, which I'm happy about.
-
Great pictures Chris. I was very cruel and let my Corydalis popovii take the full force of thiw winter without any protection! However I did give it a lovely bed of gravel to sit on!

No I only have the solida in the garden but will be trying malkensis later this year when I rescue them from the plunge. I only grow a couple of other species and apart from these it is not a genus I find particularly attractive.
Mine have originated from George Baker and Beth Evans (if they were true) plus several others I have collected seed of in the wild over a number of years.

Found this paper publishing three new species of Corydalis in China, only the first is of particular interest:
New Species of Corydalis (Fumariaceae) from China
(C. anthocrene, brachyceras, helodes)
http://www.sekj.org/PDF/anb45-free/anb45-129.pdf
It reads "Corydalis anthrocene is one of the more spectacular species in the genus, with numerous clear blue flowers and crispy clear green leaves". The black and white herbarium specimen photograph show it to be a rock garden dream.

Yes it is nice, but most of those Chinese are without tubers and impossible to grow here. Even tuberous from China isn't easy.

Well, one can dream :) C. flexuosa 'China Blue' and C. elata, two beautiful blue-flowered Chinese species, have been dependably perennial here for 8-9 years so far, so I hold out hope there are others that'll be growable.
C. elata is a terrific species, does not go dormant later in summer like flexuosa does but stays in good green growth, with a long summer season of beautiful blue flowers that uniquely smell of coconut perfume.

McMark, are you growing "true" C. elata, or the C. omeiana that was for a long time being passed around by the name elata?
See Ian's Bulb Log on the subject of these two Corydalis, with pix:

Well, that question comes as a surprise, so I did some research. It seems that C. omeiana was only described 3 years ago in 2007, whereas I had my plants (as C. elata) for over 10 years. The comments and photos in the bulb log seem inconclusive to me, without sufficient diagnostic characteristics cited. So I looked at Corydalis in Flora of China (now, there's a monumental genus to take on in a Flora... so many species, a difficult group to be sure). It seems that the leaf characteristis on these two are variable and with the exception of leaflet size, not a distinguishing characteristic. The subject plants are in the Corydalis section Elatae.
To make it easier to compare the two species, I copied and pasted info on both species and prepared a small chart of the most salient differences. I also looked at the illustrations, which are very large in page size, the one of C. elata on a multi-species illustration, so I copied out just the pertinent parts and recomposed the images to be smaller. I left the vertical arrangement of the C. elata flower, which I suppose was drawn that way just to fit onto the page in the multi-species illustration. I put all this into a PDF and uploaded it here. One key item to look at that separates Corydalis species, are the sepal characteristics.
Come this June & July when this plant is in flower, I can compare against these recorded diagnostic characteristics, to see if it is elata, omieana, or one of several other very closely related species. I also post two pics from 2001.

McMark, you may also like to see pages 136 and 137 in the book by Tebbit, Lidén and Zetterlund: Bleeding Hearts and Corydalis. If you don't have the book
I will photograph the pages for you tomorrow..... coming up in next post!

An aside to all readers:
Even if you are in possession of the Lidén and Zetterlund "Corydalis" book - ISBN 0-900048-66-2, published in 1997 by AGS Publications Ltd., I would recommend the book mentioned above by Mark Tebbit , Magnus Lidén and Henrik Zetterlund "Bleeding Hearts, Corydalis and their relatives" ISBN-13 978-0-88192-882-2, published in 2008 by the Timber Press.
At the very least it is a great supplement to the first book and I would contend it is more than that :)

I wish I had these books. From the NARGS Book Service I borrowed the "Corydalis" book, always meant to purchase it. I must get both some day. Thanks for the two scanned pages... very interesting. Missing from the Flora of China descriptions is any mention of red spots and coloration at the junction of the leaf lobes, although that characteristic is common to elata, omeiana, and flexuosa so no help in differentiating between those three species. However, reading the two pages, it still looks more and more that my plants are C. elata, here's why: omeiana has "about 10 flowers" whereas elata has 10-25 flowers, my plants easily have more than 10 flowers per inflorescence. Then there's the statement near the end that elata (and including flexuosa) have flowers with "exquisite fragrance like gardenia with a distinct touch of Cocos"... this is what I mentioned earlier, the perfume on my plants uniquely scented like coconut.
Note to myself: compare my plants with all this info, when in flower in June-July.
-
Errrrr.... mmmmm.... the omeiana is scented, too, as are an awful lot of the corydalis of various sections that we grow :D
-
Errrrr.... mmmmm.... the omieana is scented, too, as are an awful lot of the corydalis of various sections that we grow :D
Of course, but the author specifically calls out the unique coconut scent of elata. Although, I don't think scent can be used diagnostically for species identification, although interesting to take note of such features.
On the first batch of photos I posted, one can easily count 16-18 flowers per inflorescence (with more crowded buds at the apex), which is a problematic considering C. omieana is "about 10-flowered". Next I'll post some photos sent to me by Gary Dunlop in the UK (is he a SRGC member?), showing a much darker blue flowered C. "elata".

Here is a composite photo of a deep dark blue form of Corydalis "elata" sent to me in 2001 by Gary Dunlop in the UK.

I bought this from a well known bulb grower as the wendelboi x solida hybrid 'Hotlips' some years ago. Another well known bulb grower has questioned this ID. It does fit the description in Liden & Zetterlund: Dark red, a little on the cold side, slightly speckled.
Any thoughts anyone?

Of course, but the author specifically calls out the unique coconut scent of elata. Although, I don't think scent can be used diagnostically for species identification, although interesting to take note of such features.
I disagree. Flowers are not like they are to be attractive for plant enthusiasts but to attract pollinators. Scent production is energy consuming and scent can be specifically targeted at a certain pollinator. Many taxonomists consider different pollinators (and therefore different pollination syndromes) a clear sign of a different species. In other genera like for instance the "big stinkers" Amorphophallus the scent has been extensively sampled at Kew and the smell of each species had a very specific chemical content mixture. To be honest, I think Corydalis seems to be too much split, not only by the Chinese but also by Western taxonomists often mis-using taxonomy to denote horticultural differences. I don't know how much molecular work has been done on Corydalis but it would not surprise me if all the closely related blue species consist of only a handful of polymorphic species. Proper fieldwork would be the key to this and study the variation.
Granted, smell is a difficult characteristic to use in a key but that doesn't mean it is not a important diagnostic tool for taxonomy. I am not a Corydalis specialist but If I read all these characteristics I can't really be convinced omeiana and elata are different. 2 species are only truly different if there is a stable character or character set that distinguishes them. If such a character can not be found it would be unwise to keep them separate. The difference between 10 or 20 flowers to me does not seem to be such a character.

Historically, tangibly physical characteristics have been used in floral keys to differentiate plant species, although this too is a generalization, and there are exceptions. Of those plants whereby some ephemeral characteristic plays a part, there are still a range of physical characteristics that also largely define the species. Of course, we've entered a new realm of plant sciences with DNA research and other ways of delineating plants, so the rules are quickly changing.

If such a character can not be found it would be unwise to keep them separate. The difference between 10 or 20 flowers to me does not seem to be such a character.
I agree, comparing the cited differences between the two Corydalis species, there are many characteristics listed that express an overlapping range of variability (the leaves in these 2 species for example), and there really aren't strong concrete differentiating characteristics to go by. The differences I pulled out into a chart, seem to be those that are different (for example, one species having crested flowers, one without crests). I have not gone through all of the Chinese Corydalis keys... it is EXTENSIVE, but from what I've seen so far, scent is not used as a defining characteristic for the species... I thought it interesting that it was mentioned in the "Bleeding Hearts, Corydalis and their relatives" pages that Maggi scanned.
But being no expert in Corydalis, and not seen enough of them, I don't know the extent of their variability, and what key characteristics help separate them out. Moving over to the genus Allium, it can help to be aware of certain ephemeral (yet consistent) attributes as part of the knowledge of a particular species. The midwest American Allium perdulce is named for it's incredibly sweet carnation-like scent, and uncharacteristically the fact this species is heavily perfumed gets mentioned in otherwise dry botanical floras. Of course, this species is also rather distinct based on a number of physical characteristics. However, several other southwestern American Allium also have flowers as perfumed, although typically not recorded.
The converse can be true too. I grew two forms of Allium paniculatum with identical appearance, tallish light pink flowered forms, one from Macedonia which had foul-smelling flowers (rare in Allium) and the other (from another European source) had no scent whatsoever. In this example, it would be unreliable to use scent as a species determination factor.
There are lots of plant species "odorum" or "odoratum" that become assigned to a species, mostly because it's a unique or notable characteristic for whatever genus the plant belongs too. I'm reminded of the weedy Nothoscordum inodorum, which has very sweetly scented flowers, but the name was given for this species lack of an alliacious scent in the foliage and bulbs typical of Nothoscordums.
In 1994, in a publication "New Taxa in Allium L. subg. Melanocrommyum from Central Asia" by F.O. Khassanov & R.M. Fritsch, a new subsection is published as "Subsect. Odoratae R.M.Fritsch", for a group of allied species where the flowers are "intensely sweet-scenting somewhat like hyacinths, not faintly honey-like in most other Allium species". Of course, there are important physical characteristics that also help define this subsection... a rather articial grouping or organization tactic used in large genera.

Here is a comparison of the same bed of Corydalis Beth Evans flowering om March 17th 2009 and March 24th 2010.
I know the light is different but I feel that this year's are a much stronger brighter colour. I thought maybe it was because it was further on in the year but it is only a week difference :-\
Susan
-
Hi Susan, since you first mentioned the colour being more intense I have to say that I do agree to some extent that the colours are perhaps a bit more bright this year.
This could be due to a number of combined factors the cold and the light levels being two of the main ones.
However I think the light we view them in also comes into play and this becomes even more extreme when seen though a camera.
Look at the two pictures below both exactly the same plants of Corydalis 'Beth Evans' taken about 4 minutes apart from different directions and you can see how important the light you take the pictutre under is to the colour we see.
Not so impressive as your great expanse of pink.
-
Hi Ian,
I see you point but I still feel they and other bulbs are better coloured this year. The other noticeable one was Iris Katherine Hodgkin, often it is a bit wishy washy but this year it seemed quite a strong colour (not virus :) ). I know mecs change their colours if grown inside. Mind you after the weather we are having here at the moment all the corydalis flowers will all be affected by the frost, although it doesn't permanently damage them it can take the colour out of the top of the flowers :(

I observed that Corydalis color varies in quite great range from season to season, especially prominent it is in red-pink colored varieties (not in all). In greenhouse color is different, too.
Janis

My Corydalis solida plants are starting to flower. Looking at my digital photo records, they are flowering at least two weeks earlier than normal. Since it is cold and rainy today, here are a couple photos from 2009 of unnamed color selections, they seed around all over the place... love it!
-
Here corydalis only showed noses out of soil in open garden. Pot plants usually are not very typical in color, so I prefair to picture them outside, but few are quite risky for outside conditions because for early blooming they can be seriously damaged by night frosts. Of course they are not easy in greenhouse, too as sometimes inside are too hot.
Now very rare and almost unknown in cultivation Corydalis repens from very Far East in Siberia. In nature 3-4 flowers on stem, much more in cultivation. Note white spotted leaves.

It very slowly split and set only 2-3 seeds in capsule, so increasing is slow. I had quite good stock but ... in some winter almost nothing left :'(. I restart from 2 small tubers, now I have 3 pots only. Of course - I try to increase this tiny beauty. By the way - it is interesting that a pair of Japanese fritillarias growing not very far has similarly white spotted leaves.

Corydalis hybrid of unknown origin found by Henrik Zetterlund as accidental seedling and named COSMIC RAINBOW

some Corydalis from this weekend,
Cory.malkensis
`` malkensis x solida
`` integra
`` nariniana
-
Dirk, very attractive malkensis x solida, your own cross?
In the garden here;
Corydalis alexeenkoana - in recovary
Corydalis decipiens - is this solida ssp. decipiens yet?
Corydalis soilda 'WHITE KNIGHT' - superb vegetative increase.

Usually Corydalis gorinensis is between the earliest to flower, but this year last tuber of it still is only coming up in greenhouse as well as its close allie - C. magadanica. May be this is for very strong winter without warmings breaking dormancy - so it is more similar to conditions at their homeland.
On attached pictures you can see the last tuber of gorinensis blooming in garden when I collected its seeds. From first crop of seedlings I got a lot of hybrids, generally 3 types. Two were identical by leaves and flowers, only blooming time was something different and they looked very far from mother plant, but they set seeds so I wait splitting in following generation. One plant had leaves of gorinensis type but strange flower color. On the last picture you can see splitting between seedlings of outside grown gorinensis got in last year of its existence - tuber that season rotted. There are still no flowers, but leaves show that each plant again will be different.
In additional pictures of few Corydalis blooming now in greenhouse
Corydalis henrikii
Corydalis integra and
Corydalis paschei

Few more Corydalis pictured yesterday (today again dark and cloudy).
Corydalis received 3 years ago as ambigua from Chen Yi certainly isn't ambiqua, as this species grow only on Camtschatka, Russia, far from China. Leaves are very variable, but flowers strongly resemble fumariifolia.
Several forms of one of most beautiful Corydalis - brightest blue and very early C. fumariifolia, sometimes too early for outside as leaves can be damaged by late frosts.
Returning to earlier shown C. repens. I'm really schocked for size of its spikes in greenhouse - never saw so large in garden. On other picture another clone of same species with much more bright spots on leaves. Pity, but this one not bloomed this year.

This thread is a revelation 8)
Agreed, almost too many sumptuosities (<--just made that word up ;D) to take it all in, although I must say that C. gorinensis is fantastic, the foliage is like a hellebore, and such pure yellow flowers. Any idea about what species might be behind Cosmic Rainbow, those fluorescent red stems are something! And the blue one, well... they just "send me" to the edge.
I note in the Flora of China, that C. ambigua is on the list as "tentative". Does anyone know a way to get a full listing of the Corydalis in the online Flora of China? As it is now, one must know what section the species in, and there are so many sections, it makes it very difficult and time-consuming to use. Even google searches don't seem to drill into the FOC corydalis species list and find them for you.
Lastly, I have a small, pathetic little Corydalis that has done virtually nothing in the past 4-5 years, it came as C. marshalliana. Can anyone comment on this small yellow-flowered plant.

Yes, it is marshalliana, although now regarded as form of cava, but I don't agree with this.

Mark,
If it develops as other cava types you should eventually get more flowering stems, a better display will require more tubers.

Both cava and marshalliana are very easy to break tubers and normally every part makes new growth. It is the very easy way for this group as tubers (especially old) are hollow and thin. Sometimes difficult to harvest without breaking. Only young seedlings are too small for breaking.
Janis

Thanks Chris and Janis, my little plant does look like the C. marshalliana in the link you provided. I think I have it in too dry a spot, so will move it to a better spot and see if it grows any faster.

Thanks Aaron, that works for me, I downloaded the PDF. Yes it is a daunting piece of work, at 465 species :D Janis, there is an entry regarding C. ambigua, several subspecies of ambigua listed as synonyms with C. fumariifolia, and at the bottom of the species description for C. fumariifolia, it states regarding one of the synonyms: C. ambigua f. multifida Y. H. Chou; C. ambigua lusus rotundiloba Maximowicz; C. lineariloba Siebold & Zuccarini var. fumariifolia (Maximowicz) Kitagawa; "This species is represented in China by subsp. fumariifolia".

Heya, I must say that the Corydalis solida seedlings just keep on giving; such good colors for free in the garden. This bright red one caught my attention on this unseasonably hot day, 86 degrees F (30 C) matching the 120 year record for such heat. It'll probably snow in a few days from now ::)
-
That's a very fine red Mark. They seem to do exceptionally well in the right gardens.

It is nice having a few good color forms around, now I get little red-flowered ones like this popping up all over the place. Need to get some of the other named beauties to enrich the gene pool.
One that I thought I had lost a couple years back, C. cheilanthifolia, even though common, it is such a bright species for a woodland garden, I'm so pleased to find a plant blooming in my woodland, obviously a self sown seedling. I've seen photos of this that show the beautiful foliage to be quite variable, such as one grown by Todd Boland on Nova Scotia:

I dont know. It appeared as accidental seedling out of pots in Gothenburg Botanic Garden and was noted and marked by Henrik Zetterlund. But it is very possible as between my triternata seddlings one specimen is similar to Cosmic Rainbow but not so excellent as Henrik's plant, so I planted it out of collection under shrubs on roadside.

Are you sure that's always true for the Chinese plants as well? See the pictures below from Heilongjiang, borrowed from page 43 of this book (http://www.docin.com/p-19282649.html). That said the flower colour seems a bit off, so I would be happy for other suggestions of what it might be :)

I used several Russian Floras for plants of Far East and everywhere just those spots are listed as important feature, but of course, thaere can be variability in Chinese plants, leaves looks similar, but foliage dividing in Corydalis is so wide... Tomorrow will show pictures on another sp. from Far East - fumariifolia - there are specimens with same shape of leaves, with very neerow and long leaf lobes etc. I think that in Corydalis monograph this feature (spotted leaves) is mentioned, too (can't check at present).

Two more hybrids. The first is hybrid between C. tauricola x caucasica. I think raised in Gothenburg,
another very unusual hybrid between C. bracteata and unknown - this appeared between my seedlings of bracteata. The pollen parent judging by leaves coulb be gorynensis (yellow) or magadanica (white). If it will be good increaser - I predict great future to it.

Thanks! I've had this plant for years, but thanks to the wind, my cats and my own clumsiness I think this is the first time the fragile thing has flowered.

my absolute favorite Corydalis is the blue/white bicolored Corydalis ussuriensis.

The northernmost population of C. intermedia is near the polar circle in Finland.

The problem is mice who will try to dig out the tubers. I use metal net 5-6mm square in the soil. If the top growth is eaten, they will probably send up a second stalk.

janis-full sun spots are at a premium here, though i do have many places that get sun part of the day while it is high in summer;
panu-always good to see things growing in a cold place ;D
gote-i don't have enough experience yet on this property to know what my animal problems will be--there is plenty of wildlife in the woods, but so far i have only seen signs of deer and moose coming to eat the shrubs in winter; i think as i have more species green when natives aren't, i might have more trouble..as for who will eat roots and bulbs, i will have to see how it goes--mice are abundant under the snow in winter, but i assume they cannot get into the soil at that time as it is frozen-maybe i am wrong and they dig right throught the frozen earth?
do you put the metal on the surface or all around the tubers?

gote-i don't have enough experience yet on this property to know what my animal problems will be--there is plenty of wildlife in the woods, but so far i have only seen signs of deer and moose coming to eat the shrubs in winter; i think as i have more species green when natives aren't, i might have more trouble..as for who will eat roots and bulbs, i will have to see how it goes--mice are abundant under the snow in winter, but i assume they cannot get into the soil at that time as it is frozen-maybe i am wrong and they dig right throught the frozen earth?
do you put the metal on the surface or all around the tubers?
For a single bulb I get a piece of metal net. 6x6" square, 1/4" mesh. It is best if the net is wowen so the wires can move. I bend down 2" on each side to form a kind of basket. The corners will form "legs" which I twist and sometimes cut off. I make sure the soil is loose to sufficient depth and plant the corm 1.5-2" deep with 1/2" layer of soil on top. I then press down the basket (upside down of course) so the net is at least 3/4" below the soil surface and fill in. This will prevent the mice from getting at the corm. It is important that the net is below soil surface at all times. A plant will easily get through below ground but will be trapped if the net is at the surface. The added advantage is that it is easy to locate the corm again. It will sit in the basket. Of course it is necessary to replant often. A Corydlis solida is likely to double each year and the basket will soon be crowded. However, if I have many, I sometimes do not bother with all of them. If I have more bulbs/corms of a kind, I make a larger basket. I try to do this for all precious bulbs/corms (that are not big and planted deep) except amaryllidaceae which are not eaten by rodents.
I have never noticed mice digging in frozen soil.
To keep the deer out I use a 6' net around the area. Chicken net on wooden poles 4 yards apart. It is rather flimsy (and ugly :() but the deer do not bother since they can feed in other places. Outside of the fence I sometimes put a piece of chicken net over plants that I want to save. Ugly but it works.
Cheers

PS
I train shrubs and climbers to the fence so the ugliness is somewhat hidden.

i will keep this in mind, and watch to see where i will have problems.. so far i have not thought of protecting roots/bulbs from above-we don't have true moles, but we do have pocket gophers that i worry about, which come from below...
there are fences available here specifically to keep deer out, but of course expensive over a large area.. there are some bits of wire fence around the property that i will use around some vulnerable spots-esp the veg garden for now-they are not really high enough to keep deer out (the deer fences seen around here look like stiff metal, and i think they are over 7 feet) but i think it can discourage them, when they have lots of natural habitat around to feed in...

Few corydalis solida cultivars from my garden, but as first Corydalis ornata from Far East (Siberia) in all its variability - as I'm writing in BURIED TREASURES - it resembles stormy see with all shades of blue, lilac and white foam on top of vawes.
Corydalis solida Loth Lorien
Corydalis solida Preludie
4 Corydalis solida Pretty Baby - with soft light green leaves
5 Corydalis solida Rivendell

You have some fantastic solida-cultivars, Janis!
The "aff. repens" is flowering, quite an unusual pale turquoise with a darker midvein. Also below; 'Frodo'.
-
...and some foliage pictures. 'Eric the Red' is easily recognizable, the rest are Chinese.
-
The foliage of 'Eric the Red' is beautiful. What is the flower like?
-
Like this; it's a turtschaninovii-seedling if I remember correctly :)
-
That is really gorgeous! :D
-
...and they've finally started :)
Pics 1 and 2 is an unidentified Chinese, and one of my favourites.
Pics 3 and 4 are C. ornata, showing some variation from seeds.
Pic 5 is labelled as being Chinese, but I suspect it's a weed.
Pic 6 is C. cava (or used to be?)
Pic 7 and 8 is another Chinese species.
-
Why do you think pic No. 5 may be a weed? Is it seeding around badly? It looks very nice, to me.
-
It looks like C. solida, a European species, so it must be a stray seedling. They do seed around badly, I don't mind the "Penzas" doing it, but the plain species is sort of muddy coloured and best left to invade the lawn... The blue ones reseed as well, but not as bad.
-
One man's drink another man's poison ;D
But I agree.
Göte
-
Some of the earliest (in my place) Corydalis:
Whitish 'Penza', I think these are all the same clone but they also seed themselves and seem to come true
Corydalis malkensis is a very nice small one with larger liops. I seems not to be self sterile
'Rosalie' from Janis of course.
Unnamed big blue seedling. perhaps offspring of 'Blue Gigant'
The blue comes out bluer than life. It is more grey.
A bird?? had the buds of several including my nice 'Frodo' >:(

I can never see too many of these lovely plants. Thank you everyone.
-
Among all these austere Corydali, here's a common one (a weed :P), Corydalis lutea, but a single plant that cropped up having orange centers. Is this a normal variant, or do I have a new color form of this seed-everywhere-in-the-garden Corydalis?
-
Wow, Mark, that's really cool! I've never seen this weed in such a party dress. Save some seed for me! ;D ;D
Jamie
-

Well Jamie, if this orange-centered form holds true to C. lutea's intentions to seed itself over the entire globe, I should indeed get seed ;D
-
There are weeds and weeds.
Corydalis lutea (or pseudofumaria lutea) is very easy to pull out (or rather off) and it flowers a very long time so I am quite happy to have it. Its close relative Corydalis ochroleuca (Pseudofumaria alba) is similar but slightly larger and nearly white.
The one you have is new to me and somehow it does not look quite like C lutea but that may be the angle of the photo.
Anyway, I would also be happy to receive your hopefully abundant seed.

Now, that's the spirit! Let's get this form to Europe before we have an embargo on plants! after all, it is a native. ;) ;)
-
Göte, I agree, C. lutea is a very manageable little "weed", I like it. Sometimes it scares me in early spring when I see shear carpets of seedlings coming up in garden paths, but walking on them largely "does them in", and they are of very little root so are easily pulled out, but I do allow them to fill in and provide color all season long, until cut down by frost in the fall. I received seed of the white form of lutea, which I broadcast outside in the garden, haven't seen any results yet.
I might be premature on the orange-centered form, just ran out to the garden and snapped some photos. The one I had photographed previously, those flowers are going over, and there are more buds coming so will wait and see if the orange color is consistent, but I noticed two other plants with normal yellow flowers but just one or two flowers on a plant having the orange center (2nd photo). In the third photo, the first plant in the lower left is the one that had the 4 flowers with orange center.... I'll keep and eye on it and report back.
If indeed this color aberration seems stable, I'd be happy to share with Europe :D

Yesterday I found the following seedling. It has a slight "frodo-look" but since Frodo is on his second year in my garden he can hardly be the father ;D I assume a mix of white Penza and one of the reds.
The next one I acquired from Gothenburg as "small white lativan". It is indeed small and has the curious habit of lying flat against the soil surface in the early stages.
Marshalliana from Janis
kutznetzowii also from Janis
'Evening shade' also.
Most of the pinks in the last pic are 'Munich sunrise'.

Lovely bicolour seedling! Is 'Munich Sunrise' much different from 'Beth Evans'?
The early ones are going over here, first picture is my favourite Chinese, which may or may not be C. fumariifolia.
Pics 2-3-4 are C. turtschaninovii ssp. vernyi again, it's actually quite nicely fragrant.
Pic 5 is a white C. ornata.
Pic 6 was sown as C. glaucescens, but it looks a lot like yet another weed... :P
-
some Corydalis
-
That last one looks interesting, is it rhizomatous?
-
On 4th April a friend and I visited the National Corydalis Collection at St Osyth in Essex. Rather a delay in posting as I forgot to take my camera but borrowed my friend's and she has kindly put them on disc for me (Thank you Irene!)
Brian Wickenden has around 100 taxa of corydalis beautifully displayed in an immaculate and very interesting garden. Open again on 6th June if anyone is in the area - it would be easily combined with a visit to Beth Chattos. See http://www.corydalis-collection.org.uk/

This looks like a very interesting place but planted like that they are begging to produce hybrid seed! (Not that I would mind. :D)

Munich sunrise may be a little lighter in colour It is much easier to grow in my place. It doubles yearly if replanted often enough. I get seedlings very similar al over the place.

Gote, "Pink lips" is very nice :D

I hope the picture is clear enough but anyone any idea what species the one on my picture is? It's from China and has a rootstock consisting of the remnants of the base of the leaves. New foliage is bronze. No flowers yet but I hope that by knowing its ID I can treat it more appropiate instead of guessing what its cultural requirements have to be. Thanx in advance.

It's impossible without flowers, but when in doubt, treat it as a woodlander - and this certainly looks like one!

One of the last to flower here is this Chinese C. turtshaninovii, only 'Eric the Red' and a Japanese C. ?ambigua are later.

meanwhile, the native C aurea is just starting to flower here...
-
Always try Cohan. I had seed 3 or 4 years ago of a couple of species and though it was old seed, there was some germination. You may not get lots of plants but even one or two are worth the effort and are a start. Never say die, in fact. :D

thanks for the encouragement, lesley :) i got them late winter/early spring, so they went outside, and there they will stay, potted, enclosed in a baggie, until either i see something, or next spring, at least..i would love a whole batch, but you're right--i'd be thrilled with just a couple :)
i perhaps should contact a couple of the vendors and see if they would send notice when some of these short-lived seeds are harvested-otherwise, i suspect by the time catalogues are finalised, they are already old!-apart from kristl, who moist packs--i haven't seen anyone else doing this...

Can anyone tell me what this rampant thug is? It's a bit coarse, seeds itself readily, and grows about a foot high with the same spread. I grew it from some swapped seed several years ago.

C. ophiocarpa, I think.

Ah, thanks! That sounds a familiar name.

My Corydalis are of course later than most but now the blue ones have started.
Corydalis nobilis has been semi-naturalized in Sweden since it was imported by Carl von Linne. It is quite nice and fragrant.
The mixed pic shows whitish colida penza red seedlings and yellow bracteata.
Corydalis ornata has a very nice blue "lipstick"
Corydalis 'Amur' is a clone I have from Janis (like most corydalis actually) It is very vigorous and beautiful.
Red corydalis is a good background to Scilla rosenii I think

I just deadheaded the named solidas, and threw in some white and blue ones for good measure - PM me with address if anyone's interested.

Touring the amazing garden and nursery (http://www.jpwflowers.com/) of Jan Sacks and Marty Schafer in Carlisle, Massachusetts, USA, there was considerable interest in this wild unnamed form of Corydalis flexuosa which has better flower power and plant constitution than many flexuosa selections. It is such an electric blue that the eye is instantly drawn to it, no small feat in this vast and wondrous garden.
-
That is a beautiful flexuosa Mark, Unfortunately I cannot grow them. Their habit of trying to stay green during the winter is a disaster in my climate.
The last of the "bulbous" ones is now in flower. C buschii.

my native cory- Corydalis aureahas been in flower for several weeks now, and will continue through summer; because plants are biennial and don't usually seem to seed back in to the same spot (they like disturbed soil, and most spots here grow over in a year or two) i have to hunt for them over again every year..luckily, they have also sown themselves into my yard in a couple of places, so i should be able to keep track of them and get some patches established..
this is a good year for them in the bush, and i have found them in several places--i don't know how they spread-the seeds are heavy, yet turn up in widely scattered sites..they are assoicated a lot with soil turned up by pocket gophers, as they like the loose soil, don't know if they spread the seeds...

quite possible--but we are talking about plants scattered very thinly over a large area--say very roughly 4-6 locations with one to 3 plants over something like 75 hectares..the ants could spread them some metres from the plant, but (i'm speculating, no ant expert) i guess the ants will not cross the territory of many other ants to carry the seeds many hundreds of metres? the way this species quickly turns up in disturbed soil though, i suppose there could alsobe pre-existing seed in many places that doesn't germinate until the right conditions arrive..

Most Corydalis growing in forests have ephemeral seeds but this refers to perennial species. An annual or biennial would need seeds that persist otherwise the species could be wiped out by a bad year. I am also not an ant expert but my guess is that they may not go further than say a hundred meters (Help Anthony!) which is not enough to explain your spread.

kristl has mentioned that seeds of this species are not ephemeral, as you suggest..somehow, this is a good year for them--i have seen the species in more places on the farm than ever, and quite different places than in the past... of course, i should not suggest that this plant is an exceptional mystery for dispersal--there are many plants that are widely scattered..no doubt many different dispersal mechanisms at play..

Time to revisit an old issue, the identity of a Corydalis shown previously as C. elata, with forum members saying the true identity is C. omeiana. However I don't see the issue as clear cut. My C. "elata: are in full bloom, have been for nearly two weeks; much earlier than normal given our extremely early spring season this year.
Referring back to the original thread... I prepared a PDF document that listed the salient differences between the two, copied & pasted the Flora of China (FOC) species descriptions and line drawing, for easy comparison. Refer also to Maggi's scan of two pages from Tebbit, Lidén and Zetterlund's book: Bleeding Hearts and Corydalis.
http://www.srgc.org.uk/smf/index.php?topic=4903.msg145306#msg145306
I have examined the plants critically, and unfortunately, the keys and description just don't match consistently for either species, so maybe it means going back to the keys in FOC for Section Elatae, and finding out what species does fit it best, if any. It is also possible (and I'm suspicious of this) that the FOC descriptions are splitting hairs and don't properly take into account the natural variability of a plant species, thus impossible to snugly fit a plant into one species description or another, a frequent problem with botanical keys. Here's what I found:
* radical leaf size is large, generally to 8 cm (like C. elata)
* long-stalked lower leaves to 8" (20 cm) (like C. elata) (unlike C. omeiana with generally shorter basal leaf petiole)
* sepals do not entirely match either species. Sepals early deciduous (like C. omeiana) but they are only 1 mm long (like C. elata).
* flower density, terminal raceme on average 20-30 flowered (like C. elata). (unlike 10-15 flowered in C. omeiana).
* flowers in raceme all around (like C. elata). (unlike C. omeiana with that are "conspicuously one-sided")
* no crest observed (like C. omeiana) - inconclusive to me, as the FOC drawing of C. elata, I can detect no crests. In the Zetterlund book, the description of C. elata makes no mention of crests. The "pronounced gibbosity at the base" of the lower petal matches C. elata.
* stigma shape and characteristics (like C. omeiana), although not shown in drawing of C. elata, thus inconclusive. (requires powerful magnifying lens or microscope!).
So at best, I think we can call this plant as shown in my photos, Corydalis aff. elata, or C. sp. Section Elatae, or some such. The Section Elatae key is long and daunting, but if I have time, I'll try and go through it. Meanwhile, on our seemingly endless warm summer-like days, working in my shady woodland garden amongst Epimedium and other plants, this Corydalis wafts an enticing sweet perfume with heady coconut overtones... a treat for the senses.
3 photos explained:
1 Lifting up about 5 stems, showing the density of the terminal racemes.
2 Not mentioned in any of the descriptions for C. elata or C. omeiana, is that the cauline leaves most often sprout sub-racemes of flowers, they're not just simple cauline leaves. Some stems have regular cauline leaves without sub-racemes, but the majority do produce flowers with lower flower count than the terminal raceme.
3 Close up of one terminal raceme, I counted 30 flowers, which seems typical.

Hi McMark
I agree that there is still a lot of taxonomic work to be done on Corydalis but check out
Bulb log 25 2009 (http://www.srgc.org.uk/logs/logdir/2009Jun241245845561BULB_LOG__2509.pdf /) where you will see some pictures showing the large long stemmed basal leaf found on so called true C. elata.

Hi Ian,
Thanks for the link. But it confirms my point, that if one examines a plant point for point, characteristic for characteristic, the plants might not match up precisely with either species, C. elata nor C. omeiana, but to some extent fit both species depending on characteristic looked at critically.
My plants have the large long stemmed basal leaf found on true C. elata, as well as the high flower count on true elata. My plants have more characteristics matching "elata" than it does for omeiana. I believe it is necessary to revisit the keys, and who knows, maybe the plant is actually C. harrysmithii.... which it actually seems to fit closer to... and that species description actually mentions the "axillary racemes" which the subject plant has, whereas descriptions for elata and omeiana don't mention axillary racemes. C. harrysmithii is also listed as being very close to elata... perhaps these "species" are too finely divided.
-
Due to the wet weather in Holland this plant is still going strong and giving a good second flowering. Bought as omeiana but turned out to be Corydalis elata as determined by Magnus Liden. According to him: "apart from obscure vegetative differences, C. omeiana can be recognised when the flower is in bud by the lower petal embracing the upper, and the rather large rugate sepals that fall early"
-
Does anyone with a copy of the Liden-Zetterlund book on Corydalis, willing to take a photo of the cover and post it here or email it to me, and allow permission to use the photo to post back to Amazon; they're lacking a photo of the book for some reason on their site. Thanks.
