i moved some plants with tiny bulbils as well as fairly mautre plants last year and they came back fine this year. i would expect most of the foliage to die down once you move them...so maybe wait until the season is over if you want to enjoy the flowers and foliage? i guess you could try to dig up a clump of earth without disturbing the roots too much, too. i haven't tried that.

Now is a good time to move. As said get a good clump with out disturbing roots. Keep well watered after transplant. As there name implies they are hardy!

I agree, if they are already sprouting, then now is as good a time as any to transplant them. They do tend to be a bit weedy, as they drop little bulbils everywhere before going dormant in the fall. They are easy to pull but you really need to keep after them.

BTW Begonia grandis should be a pretty good companion for bleeding heart, as the latter comes up early and goes dormant early, whereas the former comes up late and will fill in the space left by the bleeding heart.

Have been finding tons of babies from last years bulbils under my established plants. Getting those transplanted now to new places so they can have time to establish and bloom this fall and set more bulbils. The babies are very easy to move. Just plant in good friable soil and keep well watered. How Fun!!!
