Thanks for your honesty! This is what I like about the forum, I can get information from an actual person that has been watching the plant for some time. I know the hybridizer might not have all the facts when they register the plant. Maryott's and myself too have found many daylilies that are listed as semi evergreen and they were very dormant.
I do try to stay away from the hard dormants because I do not think they will appreciate the heat here. Some have said they fizzle out after a couple of years. But sometimes I cannot resist the beautiful ones and even if it does die, I can at least enjoy it for a little while.
I do not have Photoshop but I do a lot of the same things you do with just my edit feature on Windows Live Photo Gallery. Once in a while I use the PIXLR.
