hi,! Yeah, the prices go up and up! I personaly have never paid over $14 for an iris. I just don't feel that waiting a few years for an iris is a big deal! Of course, as I get older, if I want to see them in bloom, maybe I'll not be able to wait till the price goes down!!LOL You should be alright in your zone for quite a while, yet, Jo Ann, I would think. I'm in 5a, and figure i've got 8 weeks of good growing weather, at the very least....Arlyn
