Hi, I have to tell you that all plants with the exception of hybrids form seeds, whether they are able to germinate is another matter, I would think that you can grow plants from the seeds from your bleeding heart, however, I would think that you would need bottom heat and even then, they might not come good, but on saying that, what have you got to loose, if you have the seed, then dry it off and either store it in a dry cool place till time to sew, or take some cutting, they I think would be quicker and have more success in increasing your plant stock, to take the cuttings, you will have to wait till next spring, when you see the new shoots come through, and they are about 3/4 inch high, gently scrape away some soil around the plant close to the stems, get a sharp knife and cut downwards holding the cutting in your other hand, make sure it has a tiny bit root on it and pop it into a pot of compost, water and keep on a semi sheltered place away from hot sun, keep watering and you should get it to grow into a new plant, you will prob get 4/5 cuttings in the same 6 inch pot, good luck.

I started with one bleeding heart plant...I now have enough to share with anyone that wants them! When the plant goes to seed and the seeds dry on the stem, I just go around and tap/shake the plant. Wherever the seeds land, I have new plants next year! (of course, the wind/rain also helps with the seed spreading if I don't get to it first!). I wait a year until the new plants are larger, then I dig them up with a little of the dirt around them and move them.
Bleeding Heart is one of my all time favorite flowers! I havent seen it in my local center as of late!
3doxiemom, if you have enough to go around I'd love to exchange addresses and get some of your seeds to plant! would I put them down this year (as if they fell naturally) then let them come up next????
