Thanks everyone. Tom, Tu Tu T was introduced by Paul Black in 1988. A little story.......I gave a start to a neighbor many years ago. She passed away and 2 years ago I drove by her empty home and saw little iris blooming. They were the ones I had given her. I talked to her son and got an OK to go rescue a start as I didn't grow it any more. Glad I did. There are a couple more SDBs opening this morning and I will take pictures the evening. We are supposed to have a cold front come next week. Hope it doesn't freeze.
