I call this daylily, whose name was lost long ago, "Lemon Yellow." It is a very plain daylily, but performs well in my garden. The 5 1/2" flowers rise on 26" scapes. I have wondered if it might be the somewhat taller Star Dream , but I can't confirm it. I have had these for years; they bloom from mid June until mid to late July and make a lovely statement in my garden.
