I've seen yellow and blue flowering corydalis, but today I learned that there is also a purple flowering species! I was browsing some online nurseries today, and a new corydalis variety called "purple bird", caught my eye. Knowing that photoshop is a thing, I was a bit skeptical and so I googled it, but it seems like most pictures of this plant do indeed have that amazing purple color. Do you grow corydalis cava, or the new "purple bird" variety? Have they done well for you?
