I thought that was just how daylilies grew? All of mine do it, whether they have good color or not. Established clumps do it. They look wilted. It really bothered me at first, but I've sort of adjusted to seeing it since they eventually straighten up and have done well in terms of bloom and increase. It's just the new center leaf growth that do it. The older outer leaves have straightened up and feel more fibrous rather than the softer, wilted feel of those floppy centers.
