Texaskitty111, do you know that you can go to your profile by clicking on the little "person" looking icon up in the left, under the big All Things Plants logo? From there, you can fill out what state, zone etc you are in. You can be detailed or vague, but helps us to know a bit about where you are to give advice. Even though your name says Texas, you could live in Indiana, for example, we just don't know for sure.
If I ** assume** you live in Texas, that is a big state, with a wide range of growing conditions for daylilies. I used to know someone who grew daylilies in Dennison, (spelling?) and had a terrible time with crown rot. A lot of the daylilies they planted died.
However, Trish, the wife of Dave, who runs All Things Plants, seems to be able to grow daylilies quite well where they live.
It's hard to say if your plants died, or sunk down in and are not blooming, but, for example, a red daylily will not bloom yellow the next year. They just don't change drastically like that. You might see subtle changes, like "melon" to "peach" depending on soil or fertilizer, but not completely different colors.
Edited because my iPad had a mind of its own on auto spell correct!
