Conoclinium coelestinum; Asteraceae (aster family)
Yet another in the series of Eupatorium-type flowers, formerly named Eupatorium coelestinum. Note once again how similar the flowers are to the others I’ve posted about in the last few days. This plant grows up to three feet tall, and has triangular leaves with short petioles. It’s closely related to the common garden plant ageratum. Its native range is from Ontario and New York south to Florida and west to the central and southern Great Plains.
Here’s a picture showing flowers, buds, and the characteristic leaves:
