Not in my books either but theres a bit on Google. Pretty colour. I love corydalis too.

thats a pain, it is such a nice plant. I have read several articles. seems to be a biennial . some say seeds freely others not.
had hoped someone might actually grow it.
thanks Steragram.

There is a warning on Google from a nursery owner that, on his land, it has seeded profusely. I can only speak on Lutea in my garden. It grows very well and very prettily. According to other Goyers they have a job getting Corydalis growing in their gardens. It is easy to pull out but likes the shady base of shrubs. I never planted it incidentally. I think it relies more on self seeding than year to year survival. That is all I can offer. People have taken roots away but it has never survived elswhere.

thanks Dorjac, i also have the lutea seeding freely, and I have a few different corydalis growing well. I just want to get this one right. If its a woodlander then I have the perfect place for it.
