needrain said:I think the lack of detail may be because different growing conditions produce different results for the same cultivar.
I agree totally with this. I grew some of my daylilies in Utah to begin with. Several had weak scapes on them, and they always flopped. I moved them to Idaho with me, to give them one more chance, and the scapes almost doubled in size on them. So, I really think it depends on where the daylily is grown, at least for some of them. Everything else about the plant remained the same. The only difference was the scape.
