Siberian corydalis (Corydalis nobilis) produces mounds of lacy, blue-green leaves accented with dense, spiraling clusters of maroon-tipped yellow flowers in early to mid-spring. They reach about 8 to 15 inches in bloom. The plants then go dormant by early summer. Though the season of interest is short, I consider this uncommon species to be a gem for the spring garden. I am able to harvest only a few seeds each year, so quantities are very limited. Because corydalis tend to germinate best from fresh seeds, I will have them available only in June and July, or until they sell out.
Sadly, I won’t have any of these seeds available in 2021; with luck, I may have some in 2022.
Please read the germination information as well before ordering.
