It is a Beauty Bush (Callicarpa dichotoma). The flowers are insignificant, though still pretty, little pink flowers. the bush will lose its leave at first frost. The stems with berries will last quite some time in arrangements in the house.
I believe it’s a bush vs. a wildflower… If so, I believe it is a purple beauty berry. Its blossom is so tiny and nondescript that you may not even see it if you’re not looking for it…. It’s a tiny pale pale pink blossom. It’s a deciduous bush that you would possibly never even notice until those spectacular purple berries emerge. I think they’re amazing!
