Corydalis Ferny Corydalis Cheilanthifolia is a compact, semi-evergreen perennial native to China. Ferny Corydalis seeds can be started indoors in winter, and also called Fern-Leaved Corydalis this rosette-forming perennial features attractive bronzy foliage with fern-like, finely dissected leaves and blooms with spikes of bright yellow, tubular flowers that appear in spring and mid summer.
Corydalis Ferny is a shade tolerant plant, so it is great for shade borders or as a ground cover in naturalized areas and woodland gardens. When started indoors, the planted Corydalis Cheilanthifolia seeds have to be kept in warm 72F and humid environment for 6 weeks. The established Ferny Corydalis plant likes to grow in partial shade and fertile, moist, well-drained soil, but Corydalis can tolerate dry conditions.
