I LOVE tall daylilies and am always looking to acquire more. The taller and the bigger the bloom, the better. I'm not as fond of small blooms on tall scapes.
I don't always remember to take full shots of clumps. Here are some of the tall ones in my garden:
Panic in Detroit (registered as 40", much taller here)
Artillery Fire (44")
Amazing Adam (51")
Starman's Quest (40")
Carl's Folly (48", at least)
Isabelle Rose (59")
Ocean Depths (48")
Tidewater Elf (39" or more)
Luna (at least 40")
I'm not sure how many pictures I can post at a time so I will upload these and follow-up below with more.
