So called 'ditch lilies' hated me. I acquired mine from a person who was unsuccessfully trying to eradicate them from their property. They looked great there, but really were taking over and overrunning everything included the alley :). They grew for me well enough, but blooms were rare. They also weren't rampant. I moved them around and even brought some with me when I relocated. Bought cultivars planted next to them did a lot better in terms of providing bloom and almost as well in providing vegetative growth. If I hadn't seen the occasional bloom from them, I'd have thought I didn't get the weedy one. It matched and I think that was the only daylily growing there anyway. So I'm thinking even a ditch lily can be choosy at times.
