Very interesting, PoppySue. I'll be interested to see what your "sportly stem" does when you root it. I grew Golden Anniversary for the first time this year, and I thought the leaves quite fascinating. The purplish flowers almost clashed with the foliage!

In August, I noticed purple blotches on the leaves, and at first I thought the dropping blooms had marked it, but I don't think that is the case. It was a very cool summer, so perhaps that's what did it. Have you had this experience with the leaves? Here's a picture.
