Any ideas? Grows wild by the road in the Ozarks, near Springfield Missouri, zone 6b.

It is incredibly tough, and drought tolerant. Two years ago when everything else was withering away, this little trooper kept blooming away in the dry dust of the roadside, despite constant mowings and crushings. It bloomed for months at +\- 8” tall due to the roadside cuttings. Naturally grows to 3’ or so.

I’m assuming it is a phlox, but feel free to correct me if I’m wrong. :) The leaves are what is stumping me. Every time I think I’ve may have found a match the leaves are thin and wiry. These are pretty wide and substantia, fairly close to paniculata leaves, but different enough to distinguish as a different species.
