Wow - you are way ahead of me! Must be further south. I have no TBs but do have Cat's Eye, Ocean Pearl, Iris germanica, Wish Upon A Star (a cutie!), Arctic Fancy and an old purple I think is Crimson King.
Love Rio Rojo! If you ever get around to dividing - just saying.....
I hope to be able to show some photos of blooming in Kentucky soon.
