Greg,
It has merely a hint of PBF.. Some fans it is absent, some, just the center has a slight blush of purple at the base.. some just a short streak. It's so minimal, I would have never considered it to have PBF... If I had even noticed it in the past.
The earliest pictures I have of it (that I can find) are from '07.. That was the first year I started keeping records of sorts (saving sales receipts, and got a digital camera).. I'm pretty sure I had it before then... Back then, Iris were just a pretty addition to the overall garden. It's possible I got it at a nursery or OSH in a mass-produced mesh bag.. I did have 'Stepping Out' back in the '80's that I got from White Flower Farm or Wayside.. I'm pretty sure I brought it to my next house.. But by the time I moved here, I had over 350 containers of plants to move. I might have left it behind as it was the move from hell, and other things got left... So that's a long story to basically say that I don't know how long I've had it. It's been in the ground since at least '06..
