Corydalis nobilis (Siberian Corydalis) [15 Seeds]

Germination Information: This seldom-seen species is notoriously challenging to grow from seed, and I discourage you from buying these seeds unless you are very patient and have experience sowing seeds of multi-cycle germinators. If you’re feeling adventurous and want to give this beauty a try, starting with fresh seed is likely to give you the best chance of success.

In the interest of full disclosure: I have not raised this species from seed myself. I acquired my first plant nearly 30 years ago and just let it self-sow as it wants to (which is apparently very lightly). The recommended germination protocol, according to the Perennial Seed Germination Database at Tom Clothier’s Garden Walk and Talk, is as follows: “Sow at 22ºC (71ºF) for 6 wks or more. Move to -4 to +4ºC (24-39ºF) for 6-8 wks. Then raise the temperature to 10ºC (50ºF). If no germination in 4-6 wks, repeat the cycle from the beginning. If the warm/cold cycles were not long enough, a new warm/cold cycle is needed.”
