Liatris aspera, or Rough Blazing Star, is native to most of the eastern United States, and is especially common in the central US. It grows in dry, sandy prairies, meadows and fields and blooms in late summer with light purple flowers on tall stalks.

This genus is a difficult one to differentiate some of the species, but the bracts below the flowers are what can be used in most cases to correctly ID them. Liatris aspera has large flower heads with bracts that curve inward toward the flower. The closest to it is Liatris scariosa, but it has bracts that do not have curved edges at all, and they are completely straight and do not curve toward the flower. See the Liatris comparison photo below.
