How to grow
Begin the Corydalis flower seed germination process in late fall or early winter indoors. Start Corydalis flower seed in a warm compost, 72F with constant humidity for at least 6 weeks. Placing the starter trays in a plastic bag will help to keep the humidity high.
After the 6 week period, move the tray of Corydalis flower seeds to a protected area outdoors where the temperatures range from 25 - 39F for an additional 6 week period. Usually, the germination starts at 39F. Raise temperatures gradually up to 50F until germination is completed. Ferny Corydalis seedlings should be planted out when they are young. They do not transplant well if they are left growing in a pot for a long period.
