I got my Bleeding Heart in the summer of 2003 from my neighbor down the street.  This thing grew like gangbusters, and had flowers on it for seven weeks beginning in mid-April.  The foliage is supposed to die back in the summer, but for some reason, mine didn't die back until November.  I was going to collect some seeds from it to grow some more plants, but I forgot.  It probably won't matter, because it reseeds itself prolifically.
