I know the couple who lived in the home. He is deceased, and she has Alzheimer's, so there is no chance I could get any answer from them. So far this most resembles Penny's Worth, Penny Earned, or Elf Caps. Eenie Weenie is too lemon yellow. The color of this is a very soft pale yellow, and I do see a slight green throat.
This has been a learning experience. I have several daylilies that apparently are considered dwarf or miniature, like Apricot Sparkles, Raspberry Pixie, Stella D'Oro, and Pandora's Box. But they seem HUGE compared to this one. Even the foliage is so small it appears almost grasslike.
You know what the bad part about this is? I am now fascinated with little tiny daylilies. Somehow I see myself wanting to find all kinds of them and plant them in my yard...and I really really don't need more plants....
