Thanks to both of you! I saw Immortality last night when I was trying to find more info, and found it for sale for $6, so I'll give that one a try. I'm not a huge fan of white flowers, but I would like something that will probably rebloom. I'm in 5a here in Utah, and I've seen TB blooming in other yards in the fall, so I'm probably going to be able to find something that will rebloom for me in Idaho, where it's warmer.
Lori, I'd be happy if I get just one that will rebloom, so it was a big help! Almost all of my daylilies are supposed to rebloom, but none of them have for me. Not even Stella D'Oro, which reblooms for pretty much everyone else. Even the ones that I've shared with friends down the street have rebloomed for them, but not for me! I've got bad luck!
