maybe Stella d'Oro

This year, they all seem to be up early.

You didn't mention colors.
My most prolific are old, old cultivars. All these are recent photos in my garden.
Salmon Sheen, 1950; was a Stout Medal winner in 1959.

This one has no name, but it's more than 45 years old.

Brocaded Gown, 1979, won the Stout in 1989

The Daylily Forum is a good source for specific information on many others.

Happy Returns is a reblooming, early variety. Nice clear yellow, goes with everything! It is on the short side..
