Because of its foliage, this petite plant is often mistaken for a summer-blooming bleeding heart. Its gray-green foliage is deeply dissected and ferny in appearance. Unlike the flowers of bleeding heart, the gently nodding blossoms of corydalis are pale yellow and white. Their bloom peaks in spring but continues sporadically until fall. The plant has a tidy appearance and will seed prolifically all over the garden, in between pavers, and even in the lawn. It is perfect for a cottage garden, where you want the plant to spread and weave itself throughout the landscape. Also use it as edging, along stone walls, or in the border or rock garden. It is a small, tidy plant with attractive foliage all summer.
