I think, not 100% sure, that this is what the old-timer's in KY call frostweed. It's an aster and blooms late (thus named frostweed). The honey bees tend to like it as a late nectar source. The scientific name is Aster pilosus. If I'm right, the stem going into the ground is somewhat woody. It is propagated by seed and sprouts from rhizomes.
