I have a few that get that way, when the weather is off, or when they have been under serious stress from the weedeater and such........ I usually do just cut off the scapes, i can deal with seeing the plant get healthier instead of knarled old blooms. Most of the time, after the plant has settled into the season, i do usually see another scape or two even on non-rebloomers, granted bud count is a little lower but there are a couple of good blooms. Also there could be other problems you arent seeing, below the soil and such, but then the plants would eventually show some signs, eventually anyway.

I LOVE my daylilies! They are my favorite perennial in the whole garden! Yours are just GORGEOUS!! How long do they bloom for you?I know that some varieties only bloom once and then stop, and I have a few of those, but as a newbie I must have gotten stupid lucky when I went to the website I love best (Homestead Gardens in MO) and picked my daylily order on pictures alone because most of mine give me at least two months of continuous bloom, and some bloom all summer for me! I only have one or two of the ones you have pictured, but yours are all gorgeous and I'm very jealous of the pink curly ribbons--I'd love to have some spiders! Congratulations on your beautiful blooms!

I haven't seen that many near whites bloom here (deer, among other reasons) but this is my first season with WHITE WOLF, which I got as a club sale plant, and I have to say that I am pleased with the "white" color. Color wise it looks near white from a distance, though up close you can detect a hint of color. (It is registered as a "cream white", though it is nowhere near as yellow as SACRAMENT OF HEALING shows in my garden.) The color pretty much looks like it does in the image above - which to me seems like a faint blush of pink. The bloom is large (6.5"), has good substance, and usually opens well. (When the nights are very cool here, it does seem to take longer to open.) Unfortunately I am currently experiencing some rust issues with it (which may be due in part to a combination of hose and sprinkler spray; we are in an arid region and normally do not have trouble with rust - at least not in the summer). It is too early to tell if would be a bad ruster or only somewhat susceptible (and I intend to move the pot and water with a can now to help those problems). Since you are in zone 6, that may not be a concern to you. For what it's worth, I have been making crosses on it this summer against other near whites (WONDER OF IT ALL, TRANQUIL HORIZON (which in my garden is near white), and SACRAMENT OF HEALING). I'd be crossing with almost every other near-white tet that I have (the taller ones, anyway), but either they are new plants which haven't bloomed yet, or else the deer got them (WHITE MOUNTAIN, sigh).

lol, head on over to the daylilies forum and check it out. daylilies come in all kinds of shapes and sizes, and flower iirc through the later summer-early fall months Here is a link that might be useful: daylilies forum
