Bleeding Heart or Asian Bleeding Heart (Lamprocapnos spectabilis) is a species of flowering plant in the Poppy Family (Papaveraceae), native to Siberia, northern China, Korea, and Japan. It is the sole species in the monotypic genus Lamprocapnos but is still widely referenced under its old name Dicentra spectabilis.
It's easy to see where the old-fashioned Bleeding Heart got its name. The pillow-like flower is heart-shaped with a single dangling pendulous drop. Bleeding Hearts are shade-loving woodland plants that bloom in the cool of spring. Although they stay in bloom for several weeks, the plants may disappear for the rest of the summer if planted in too much sun or heat.
Light: In a moist and cool climate, Bleeding Heart will grow in full sun, but in warmer and drier climates, it requires some shade.
Water: Keep plants well-watered throughout the summer, especially in warmer weather. Even then, they may be ephemeral and disappear until the fall or next spring. If you've recently planted your Bleeding Heart, it would be wise to mark the spot so you don't accidentally dig in the area while your Bleeding Heart is dormant.
Soil: Bleeding Hearts prefer rich, moist soil but are not particular about soil pH.
Fertilizer: Bleeding Heart is not a heavy feeder, so when to fertilize depends on the quality of your soil. You won't have to feed if you have rich, organic soil that is amended every year.
Bleeding Hearts can be started from seed, division, cutting, or seedling. It is very easy to divide Bleeding Heart plants. It should be divided after flowering, so you don't sacrifice bloom. The fringed-leaf varieties divide nicely early in spring as they are emerging. The Bleeding Heart can also be started by seed or stem cuttings. Plants very often self-seed throughout your garden, although not to the point of being a nuisance. Sow the seeds outdoors in the fall; the seeds need a period of freezing temperatures. To start seeds indoors, place seeds in a pot of soil. Put the pot in a plastic bag and place it in the freezer for 6-8 weeks. Remove the pot and all to germinate and grow in regular seedling conditions.
The biggest foe of Bleeding Heart is the summer heat. Gardeners in warmer zones will have a tougher time establishing their plants than those in the colder zones. Leaves are susceptible to leaf spots. The easiest solution is to shear back the affected foliage. Although Bleeding Heart likes moist soil, it can't tolerate heavy, wet soil and may get root rot if left with wet feet too long.
