Crimson-eyed or Swamp Rose-mallow
Hibiscus moscheutos /Mallow Family
I had a very angry osprey circling overhead when I took this picture! I guess I was a bit too close to her nest (on top of a utility pole) for her comfort! These plants are related to hibiscus, althea bushes, hollyhocks, cotton, and ocra.
