Destined to See has only been in my garden for a couple of years at this point, but it's a real beauty. I'm in zone 3 and Destined to See has been reliably hardy here - flowered every year that I have had it, including its first season.
It's a bit taller than the 24 inches listed and ... as others have noted before me... this daylily does put out polymerous flowers. I would recommend it.
