Liatris hirsuta

Liatris hirsuta is an erect perennial. It produces purple-pink flowers in the summer, from June to September.[1]

Liatris hirsuta is similar to Liatris squarrosa, and some authors classify it with varietal status (Liatris squarrosa var. hirsuta).[3] Liatris hirsuta is typically found to the west of the range over Liatris squarrosa, but there are regions of co-occurrence. Liatris hirsuta can be distinguished from Liatris squarrosa by its short-tapering involucral bracts, and its comparatively straighter and more spreading hairs.[3] Liatris squarrosa is also close to Liatris cylindracea, with which it has been found to intergrade.[1]
