I'm not often over here on the daylily forum, but just did some early clean-up and one of my old tried-and-true Stella daylilies is becoming a rather formidable mass. It's about a foot or more in diameter and probably a 6-8" tall mounded up mess of roots. I've chunked pieces off this mother-plant on a fairly regular basis and it just keep blooming happily. Should I dig the whole thing up and really spend some time dividing it into more manageable pieces, or can it just be left alone? It appears to be growing on top of itself to form the mound (some of my hardy geraniums do this as well). I have not noticed any diminish in blooms. This particular plant is about 20 years old, dug out of a friend's yard who assured me this plant would grow anywhere. She has certainly been right about that! I have shared it often and replanted many offsprings around and about my yard. Thanks for your expert advice. My gut feeling is to just leave well enough alone. I tried moving a Joe Pye last season and had to enlist the aid of my son to even lift the clump out of the ground, let alone break it up. I fear this daylily would be about the same.
I do enjoy all the lovely daylily photos you folks add to the database, so many different colors and forms.
