A small shrub of the Cumberland Plateau, found only on the flood-scoured cobble and sand bars of three river systems in eastern Tennessee and a sliver of Kentucky: the Big South Fork of the Cumberland, the Caney Fork, and the Obed. The rest of the Conradina clan keeps to the sand scrub of Florida and the Gulf Coast of Alabama, sun-baked and semitropical. This species took a different path, north into the cooler uplands, and the cold-hardiness that came with the move is the gift to gardens farther north.
