A large genus with over 400 species Corydalis enjoy a range of conditions from sun to deep shade, depending on the species. With wonderful spurred flowers spring to autumn. With flowers from blue through to yellow and red along with attractive ferny foliage Corydalis looks great as a specimen or when used as a ground cover plants.
Most Corydalis like damp conditions, and part shade, think woodland situation, so a well drained soil with plenty of compost or humus dug in to it will suit. They can be grown in pots or containers where a mass planting will look wonderful in spring with the masses of flowers.
Propagation is from seed or by dividing established clumps in late winter.
