Corydalis, is a large genus in the poppy family, Papaveraceae, with over 300 species, the majority native to the Himalayas and China. Many are woodland plants which thrive in moist soil and semi-shade.
Division in spring.
Seed – needs cold stratification, best sown in September - October.
Seed just covered and stored outside until germination. Germination can be slow and the seed may germinate a year later, so it‘s important to not throw it away prematurely. Seed has short viability so it‘s important to sow it as soon as possible. Optimum germination temperature is 5-15°C (40-60°F)
Yellow corydalis has recently been moved to a new genus, Pseudofumaria. Self seeds moderately.
