I bought Lime Frost in the early 2000s, from Seawright Daylilies. It was $35 which was a lot for a Daylily back then! The most I ever paid for one up until that point but I fell in love with perfect form, the diamond dusting, the green throat.
I planted it in the Island bed, where it resided for a number of years until that bed started to get overrun so I moved it to Upper Daylily Hill, near the middle.front. It's still kicking, it doesn't seem to have formed much of a clump, a slow increaser. There's also a lot of competition on the Hill. It is still putting on a good show, producing almost thirty blooms between July 18 and August 5th this summer ( 2021)
