Hi all,

I've been getting interested in daylilies the last couple of years and starting acquiring some different varieties. I got a few last year - two dormant (Tiger Blood and Shadow Walker) and an evergreen (Tropical Illusion). However, last winter, the two dormant types stayed evergreen and the evergreen type died back and lost its leaves.

What causes that to happen?

Those three were registered by long time hybridizers. I know Sandy at Riverbend daylilies and Mr Elliott are on Facebook. Try directing your question to them if you are on Facebook. Someone here might be growing one or more of these that could put their own observation into play.

Foliage habit can vary by location and environment, it's not necessarily something that is fixed in a specific cultivar and only reflects the hybridizers observation. So a daylily registered as "dormant" (deciduous) by a hybridizer in a cold winter climate may be evergreen in a warmer one and vice versa and even the other way around, e.g. Stout observed that 'Chengtu' was semi-evergreen or evergreen in New York but "dormant" in Florida.

Interesting. Thank you!
