The flowers of the herb are hermaphrodite in nature, possessing male as well as female organs and appear from early summer to early autumn.

Propagation by division.
From Early Spring TO Early Spring
Corydalis plants can be propagated by carefully dividing established clumps in early spring.
Propagation by seed
From Late Autumn TO Early Spring
Seeds should be sown directly in the garden where they are to grow, in the autumn. To start your seeds indoors, they will need to be stratified in the refrigerator for a month before sowing them, then maintain a temperature of 65°-75° within the growing medium for germination in 15-30 days.
Planting young plants
From Early Spring TO Early Spring
Plant Corydalis in full sun or partial shade and moist but well-drained, organically-rich soil. It prefers a neutral or alkaline pH soil as well. Planting them in a moist, shady area where summer temperatures are hot may help prevent summer dieback.
