Maxine, that is beautiful bloom! I have no idea which one it is, but I do hope that you will make a new thread for it. Many more people are likely to see it if you do that.
Something I used to do, which was very helpful, was to print out a list of the daylilies that I already own, and carry it in the truck. I have been known to see one at a nursery and buy it, not realizing that I already had it at home! It's hard to remember all the names when a pretty face is staring at you!
