Buttonbush is a shrub or small tree commonly attaining heights up to about 6 m, occasionally twice that size. Leaves are opposite or whorled, elliptic to ovate, 2-8 cm wide, and 6-15 cm long; margins are entire and apices are acute or cuspidate, i.e., with an abrupt, short, tooth-like point. Triangular stipules, 2-3 mm long, are located between petiole bases and have marginal gland-tipped teeth. Flowers are borne in densely crowded globose heads, 2-3.5 cm in diameter, located at the ends of stems and from leaf axils near stem tips; flowers may be found through the summer, but are most abundant in June and July.
