I have to agree my shaded daylilies seem healthiest ... I almost never have to tend to them, and even the weeds are drastically fewer. Almost all of mine are Evergreens and Semi-Evergreens, as dormants have not done well with me. What I mean is that the E/SE's go into a heat-induced dormancy, not necessarily dying back, but just no blooms at all. And, the size of the fans and roots shrinks back to a kind of miniature size. Its taking me a year of potting them up and protecting them under the porch to get them back to blooming size. On reblooming, I haven't had any trouble with my deep-shaded cultivars. Dixie Land Band and Happy Hooligan bloomed almost continuously in the deep shade, less so in the full sun. Just different gardens doing their own thing, I guess.
