Catching up here...
'Give Me Eight' is not highly polymerous here, maybe about 25% the last year that I bothered keeping records on it, which was several years ago. (For some reason, most - almost all - registered polymerous daylilies that I have purchased do not perform here per the hybridizer % data. I suspect that some combination of climate, shade, and amount of water is the culprit.)
I do like the large flowers.
