Nancy, I believe Bleeding Hearts will tolerate some sun if they get plenty of moisture. Here they go dormant pretty quickly once the temps go up- we had a couple of weeks of days in the 90s and this big one started yellowing, which is what gave me the idea to go ahead and divide and move it. They exemplify the cottage style to me too, old fashioned and graceful, which I just love.
JoAnn, I don't know how one would go about getting all those roots out of the ground, they're so fleshy and brittle they break off with the least bit of pressure. I'm very curious what's going to show up there next spring. I guess if a plant is going to be extra persistent, I'm glad it's one I love so much.
