Bleeding heart (Dicentra spectabilis) is named for the plant's pink heart-shaped bloom and the tiny drop-like protuberance suspended from the bottom of the bloom. In its natural environment, bleeding heart is a woodland plant that grows under the shade or dappled light of tall trees, and is prized by gardeners for its ability to thrive in shady or semi-shady spots. If you have access to a bleeding heart plant, save a few seeds for planting. By spring, you'll have several new bleeding heart plants.
Prepare a planting spot for the bleeding heart seeds ahead of time. Choose in shade or partial sunlight with well-drained soil. Bleeding heart won't do well where rain water tends to pool. Use a hoe or garden fork to cultivate the soil to a depth of 8 to 10 inches. Mix an inch of compost into the top of the soil.
Allow several bleeding heart blooms to wilt and die when the bleeding heart plant is finished blooming in mid-summer. When the blooms are completely dry, they will fall off, leaving a seed pod remaining on the plant.
Wait for the seed pod to turn dry and brown, which will take a few weeks. Pinch the dry seed pods from the stems. Split the pods open over a paper plate and let the small, round seeds fall onto the plate.
Plant the bleeding heart seeds in the prepared spot immediately, while they're fresh. Plant each seed about 1/2 inch deep in the soil. Water the area with a watering can or a garden hose with a spray attachment. Be careful not to wash the bleeding heart seeds from the soil.
Keep the soil damp until the first frost. The seeds will germinate when the weather warms in spring.
