Rough Blazing Star (Rough Gayfeather)

Rough blazing star, Liatris aspera, can be told from other Missouri blazing stars by its involucral bracts—the overlapping leaflike structures at the base of each flowerhead. In this species, they are rounded, somewhat spreading, appearing pouched or swollen, and mostly with broad, thin, pale to transparent margins that are sometimes strongly purplish-tinged.
