Corydalis sempervirens

Common Name: Corydalis, Rock Harlequin

C. sempervirens displays a profusion of delicate sprays of dainty pink flowers with yellow tips in late spring and continues to bloom sporadically all summer long if kept moist. Even when it's not in bloom, the soft blue-green, dissected foliage is attractive in its own rite. When sited properly, in cool, moist, partly shaded locations, Corydalis is absolutely enchanting.

Corydalis sempervirens is a reseeding biennial.

Origin:

Native to North America

Native to the NE United States and Canada, C. sempervirens grows best in moist, well-drained soils that are alkaline. Adding lime to the soil will help to achieve these conditions. Though it will grow in full sun with consistant moisture, this plant prefers partial shade, perhaps at the edge of a woodland. Though this species is biennial, it self-seeds freely, providing many new plants to carry on the show for years.
