Corydalis 2011

[Magnar]

I `ve never got seeds of C. nigro-appiculata, plant is self-steril. But division is easy, best in spring, when growth starts !

I have the same experience with my plant.

[PeterT]

thats a week earlier than mine normally is Alex, though I did notice afghanica was early here this year and others showing, I'll go to look whats through - perhaps some thing for the loughbourgh display next week 

[Alex]

A week on.....also C. ledebouriana, a Gymnospermium albertii and a general view of the plunge area containing the Juno Iris and Leonticoides Corydalis.

[PeterT]

It looks like you have background heat on Alex?

[Alex]

You mean from the relatively advanced growth? Yes, I do keep the greenhouse above 1 degree or so with fan heaters, now it's dipping below zero at night. There's no way I'd run an unheated greenhouse owing to a previous bad experience....

[Alex]

P.S. you can see 2 of the Junos you sent me in that last pic - galatica on the left of the one in flower, and caucasica front right corner - looks like that one will put up a bud.

Cheers,

Alex

[Alex]

C. popovii and C. ledebouriana today.

[Regelian]

Alex,  great plants you're growing!  I really love the species with strongly bi-coloured blossoms.  Very smart-looking.

Are the seeds especially ephemeral, as I always seem to see the same few species offered in exchanges and those I've tried had very poor germination, other than C. nobilis, which did eventually produce a decent seedling?

Keep those pictures coming

Corydalis seeds germinate very well if they are sawn immediately after harvesting. Those for seed exchange or selling must be kept mixed with substrate - I'm using peat moss. It is important for woodland species as well as for species from arid conditions. According Henrik Zetterlund - Corydalis seeds need some "after-ripening" which happens in soil. Seeds kept mixed with peat moss gives excellent germination but for own seeds the best is to saw during a week after harvesting. Then germination is almost 100%.

Janis,

this explains much.  Mine were always sown dry, except some from Krist Walek, which were moist packed.  Those did germinate reasonably well.  I'll need to find some fresh seed, then.

Great to see your plants getting growing , Alex.
I've made a transfer to a Corydalis 2011 thread for you.

The first flowers opening on Corydalis popovii from Norman Stevens here Alex. I have one with a pure white spur in the pot next to it just coming through. Can anyone tell me if wild populations have different coulor forms in different colonies?

Yes, there are different color in wild, but of common pattern. Color changes during flowering from white to pink, too.
