With fern-like foliage and curving stems bearing pretty pink and white, heart-shaped flowers, bleeding heart is an all-time favorite perennial. It appeals to children and adults alike. Bleeding heart can be grown in a mixed border or in the filtered shade of trees. Plants may reach 16-24 inches tall in good conditions, and form a clump approximately 20 inches wide. Bleeding hearts, Dicentra, grows best in filtered sunlight. Strong, hot, drying winds make it shrivel up. A sheltered position protects against late frosts. Needs well-drained soil rich in organic matter. Dig in copious quantities of decayed manure or compost several weeks before planting. Sow in March and November, divide in October, transplant in April and May, and flower in June and July. Hardy to 0 degrees Fahrenheit.
