From the "Field Guide to Wildflowers of Georgia and the Surrounding States" - Found in disturbed areas throughout Georgia, growing up to 8 feet tall. Stems are deeply grooved, hairy, and 4-angled. The flowers are clusters and very dense. The spiky flower clusters can grow up to 2 inches long. Flowers are tiny purple flowers but only a few on each cluster open at one time. Flowers April to November. Flowers are so tiny that the camera had trouble focusing unless I steadied the plant with my hand.
