I planted these last year. They do good in part shade and spread a little bit each year. They bloom most of the summer for me if I remember to water when it's really dry here.
Dicentra Bachnaal
I just planted a couple of these at my parent's home. I've never grown them before. I hope they do spread as I'll rob some of hers next spring. :) I bought some white ones (on clearance, of course) and hope they do well. Yours are lovely.
