Corydalis 2019

[Gabriela]

very nice set of colors from all of you, here's another solida hybrid 'Domino'

Interesting flower shape for a solida Yann. Do you know the parentage?

Corydalis Open Day - Durham, Co Durham
Sunday 31st March 2019


The  garden of  Brian Whitton is again open to view his national collection of  Corydalis.  This is  a fascinating opportunity to view the Corydalis Collection in Durham (DH1 4LA) on Sunday 31st March 2019. Species from the high mountains in China are of particular interest, but it's difficult to predict flowering dates, so email for information.

Plant Heritage  notice :
 Open day to see the National Plant Collection, Corydalis. Medium garden with plants in outdoor and greenhouse pots; many also in open beds. Species from high mountains in China of particular interest, but difficult to predict flowering dates, so email for information.

Gorgeous blue Gerd, are you sure it doean't have a bit of foreign blood? The flower shape is a bit unusual for solida.

[Leena]

What I'm doing now is grow them 2 years in pots to better give them a 'fighting' chance, then I plant in the garden after they go dormant (in the second year).

This is what I'm doing now, too.  I have lost seedlings in some years, when I have either sown them directly to ground or planted right after germination. Of course this would happen to seedlings which I'm most looking forward to, the more common ones (muddy purple)  just keep on self seeding no matter what the weather is like ..

Thank you Gabriela! There is more than one origin of my blue selections. I remember that I once found a single blue one in the Alps and there are also some of commerce.
However I just compared the photographed plant with other solidas and I can't detect special differences.

I must confess I am not the best oberserver concerning differentiation, so would you please tell me what is unusual for you.

I noticed self sown seedlings as well Leena, don't know the colours yet but for now even the common ones can stay; I have plenty of space to fill (will keep them on the other side of the house though

Your picture doesn't have enough detail Gerd but the spur seems a bit too recurved, I may be wrong of course.
I have never seen a pure blue C. solida (and I've witness large populations in the wild) and I actually don't know of any cultivars, maybe they exist but no one shows them.

[Gerdk]

Thank you Gabriela! I just picked a flowerhead of the blue selection - and you are right, the spur is more incurved than it is in the other ' solida ' which I grow. So some kind of introgression can't be excluded.
I am still not sure if this is sufficient to name them ' solida hybrids ' or ' aff. solida '.

I bought a bulb of C. solida 'Blue Pearl' from Paul Christian, expecting at least a blue-ish flower but for me it was not even a Dulux hint of blue. I think they must have had quite a few other people disappointed as there is now quite an extensive discussion about the unstable nature of the blue colour of this cultivar on their website...

It's up to you Gerd how to name it, I would say hybrid. What blue Corydalis species you had/have in the garden? It would help to clarify the origin.

Still nice Gail I do not cry after blue C. solida because there are enough beautiful blue Corydalis.
If we are to discuss colours, let's think that in within every species there are 'traditional' colours, some 'rare' and some plainly put 'nonexistent' - better said not expressed, they may exist genetically speaking. There are many studies regarding the genetics of flowers colours.
Corydalis solida, considering wild large populations, shows: purple in various shades, pink, white and red. Even in close species: C. caucasica, cava,...the main colours are purple to white.

So, any 'blue' C. solida sounds a bit suspicious to begin with (but not impossible). But there are still many other beautiful forms to obtain colour wise for C. solida.

Gabriela, I don't have any blue Corydalis besides the plant pictured but within the ancestry there might be another species - part of the starting material of my selection came from a nursery.

So - better will call them aff. solida.

[Rick R.]

affine (aff.) is Latin for "similar to", but in botany it means "closely related to, but likely not the same species".

confer (cf.) is Latin for "compare", but in botany it means "similar to, but not identical and may be the same species".

But in real life, affine and confer are subjectively used.  Their subtle difference is meaningful when both are used by the same author, but probably best viewed as identical from author to author.
