Thank you for posting. I will look these up. I have heard of Maya and that it is a good one. University of KY has a very large one in its arboretum.
We are in zone 6, so I wonder if they have it in a buried pot or just mulch it heavily?
The others I will look up. I never had a double before. I do think they are pretty. Do some have better substance for their blooms? I know there is a big difference in daylily blooms.
