Corydalis (Corydalis Cheilantifolia Manchu) – This is a wonderful perennial that can be grown from Corydalis seeds. Commonly called Ferny Corydalis, this ‘Manchu’ fern-leaved Corydalis is a hardy perennial that produces blooms of bright yellow. It grows about 10 inches tall and the same in width. It does best in moist, shaded conditions, and where it is happy, it will self-sow, but not in an invasive or troublesome way. Corydalis plants look wonderful growing in a rock garden or up along a rock wall. Fern Leaf Corydalis is semi-evergreen, and has bronze-tinted, fern-like foliage. In the spring, spike-like stems with yellow flowers are produced.
With some patience and care, Corydalis flower seed can successfully germinate and produce these lovely shade-loving plants. 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.
