Dicentra spectibilis, common bleeding heart

Dicentra, commonly called bleeding heart, is a genus of annuals and perennials prized for their graceful, pendant, heart-shaped flowers. Bleeding hearts bloom from late spring to early summer depending on the variety. Blooms can be pink, red-pink, white, yellow, or purple depending on the variety.

Dicentra flowers have more or less heart-shaped corollas. The flowers have two petals that are modified into pouches or spurs. Flowers appear on long stalks above deeply cut, fernlike leaves. The green leaves become autumnal yellow after the blooms have faded.

Dicentras are mostly native to lightly shaded woodlands in North America and eastern Asia. There are about 20 species; most are perennials, some are annuals.

Grow Dicentra toward the front of beds and borders. They are a favorite in cottage and woodland gardens. They are a good choice for planting alongside spring-flowering bulbs or hardy ferns. The flowers are excellent for cutting.
