Corydalis 2010

[Janis Ruksans]

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

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.

Chris, i found this seedling between my Corydalis malkensis. Not a cross from me,
it is from the bee

  Those double crossing bees!!

This thread is a revelation 

Agreed, almost too many sumptuosities (<--just made that word up ) 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.

Increase is by seed unless you want to risk cutting the tuber!

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.

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.

Mark,

 for the FOC got to Corydalis, scroll down through the key to sections and go to Related Objects and click PDF. Then just search by name with the find feature. Wow! 465 species in China...... That treatment was a lot of work.

Thanks Aaron, that works for me, I downloaded the PDF. Yes it is a daunting piece of work, at 465 species     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

[Lesley Cox]

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:

Tut-tut Mark!  Why does everyone want us on an island?

BTW Todd is on the rock (Newfoundland), in St. John's.
