Thanks Betty!
I wasn't expecting much from the flowers since the foliage was my focus, but they've surprised me. And coincidentally, two of the very best for PBF are also two of the flowers I like the most.
But the only catch is, if I ever do get an all purple-foliaged iris wouldn't it be better to have flowers that were a lot lighter than these, so that there would be some contrast?
Thanks again, Tom
