Rob,
What beardless types do you like?
Bonnie, judging from the few LA irises I grow, I really like them. I'd like to find a strong red and a good golden yellow. Some LAs are coming really close to true red.
Leslie, I believe I saw JIs being grown at Duke gardens, so they should certainly grow for you. I found they take a couple of years of settling in before they hit their stride, but they're fantastic from then on.
I'd like to get a couple of shades of blue JIs with yellow signals, and a few Sibs in blues and yellows.
