Not an expert here, but...
I think that in your climate zone dormant or semi-dormant daylilies will do much better than the evergreen type. There may, of course, be exceptions.
I've had great service from Oakes Daylilies--I've been a customer and am not otherwise affiliated. You can screen selections for color and foliage type (dormant/semi-dormant/evergreen), among other features. I think you can call or e-mail them for advice, if necessary. They may not have the exact plant you're looking for, but it's fun to browse their catalog for something similar.
I'm in 7b, had never grown daylilies before, and have difficult climate and soil with lots of herbivores visiting the yard. My plants bloomed the first year and have been strong and healthy since.
