Bleeding heart flower plants offer delicate heart-shaped blooms of pink, white and sometimes red. The leaves are constructed in a lacy, fern-like shape. The bleeding heart blooms from early spring to the first frost, depending on climate conditions. It is a shade-loving perennial (comes back every year). This plant's seeds require a freezing period in order to germinate. Although the seeds are better sowed outdoors, before winter, they can be started indoors.
Fill several seeding containers with a general-purpose potting soil, to 1/2 inch from the top. Recycle your yogurt and other small containers to use as seeding pots. Poke several holes in the bottom of each container with a nail.
Plant a bleeding heart seed in each container at a depth of 1/2 inch. Smooth the soil over the seed hole.
Place the seeded containers in a plastic bag and seal it with a wire twist. Put the containers into the freezer, in an area where they will not be disturbed. Leave them in the freezer for six to seven weeks.
Remove the seeded containers from the freezer. Take them out of the plastic bag and set them in a location that has a beginning temperature of approximately 15 degrees F. This could be a garage or garden shed, which has a bit of natural light entering. Don't get discouraged, it can take from a month to several months for the seeds to germinate (sprout). When they do, offer a good watering and allow the excess water to leave out of the drainage holes at the bottom of the container.
Transplant your bleeding heart seedlings in the early spring, after the last frost has passed. Bleeding hearts are natural reseeders. The following year, when new seedlings arise, dig them up and plant them in locations you would like.
