Overnight one of my favorite Southern Belles, the soon to be in Texas, Miss Lulu, identified the purple berries as being from a Beautyberry Bush.
So, now I know what it is. I looked up Beautyberry Bush. The berries are edible, but not very tasty. Birds don't like them, so the berries stay on the bushes unmolested. I think I'll taste one when next I see one.
