This was one of the mysteries I bought last summer from a fellow that grows and sells Iowa natives. He rambled off the names of everything, but could not remember all he said. I have been trying to identify these things on my own. A few I've been able to, but this one is tricky. The top photo was taken in August, and the bottom earlier this month.
There is much variation among the flowers and leaves on this page that I am not sure it's this plant.
Wild Petunia (Ruellia caroliniensis subsp. ciliosa)
Thank you so much.
