This is probably a really hard one, since there are so many purple daylilies similar to this one. It is 5"m 26" tall, early bloomer.
Theres no way to tell what these are, would be guesses at best. Might not even be named varieties.
Guess, yes.. but mine is strutters ball..
It really looks to me to be in the form and color range for it.
I actually have Strutter's Ball. Side by side in person they are different.
