Hi Marilyn, I just got around to reading your thread, I agree on it being a really good idea. Here's what I have this year and my comments:
Baltic Star PBF OMG what a performer, every year! It seems to grow in my sunny location and location with some shade during the day. I got tons of it. It reproduces FAST and lives through the rabbits!
Los Coyotes: Grows fast for me, I put it in some of the worst soil you can imagine, ( I knew nothing about iris at the time) hard clay and it just took off! I divided it last year but I bet I have plenty to share this year.
Pop Star: I got it from Stout and it bloomed the next year with several buds. Unsure about dividing it this year too new yet
Sun and Sky: Blooms every year, good increaser, very nice plant, I should divide it this year so I'll have some to share
Uncle Charlie: Bloomed the next year after planting with several buds. Really nice looking plant. I'll have to check this spring but it had more than doubled it's size in one year
Vapor: Impressive grower for me in both semi shade and full hot sun. Late bloomer but it has bloomed every year. Doesn't seem to increase as fast as the others above but what a show. I have extras to share
