When I took the photo it was almost ready to rain and I didn't want to use the flash. I was going to try again and now my camera won't work. There are 13 petals on each bloom.
Hopefully I can get the camera to work and take another photo. The stalks and stems are a deep purple and looks so good with the yellow flowers. Jim
Went out and looked again and some of the stalks are purple and some are brownish purple color. I got it beside a rail road track in Alabama several years ago. Went back several times since then to the same spot but haven't seen any more. Jim
