I've only had mine one bloom season. I don't have a big daylily collection, but this is my favorite in my collection. It hasn't increased yet. Nothing much else has either. I have rocks and clay or rocks and sand. I didn't bother to measure the scapes, but nothing gets as tall as its potential here. I tossed some composted chicken manure around them all a couple of weeks ago - their first feeding ever. It's sink or swim in my garden, and daylilies are swimmers here.
