Liatris hirsuta
Liatris hirsuta, commonly called hairy gayfeather,[1] is a species of flowering plant in the family Asteraceae. It is native to North America, where it is found primarily in the Midwestern and South-Central regions of the United States.[1][2] Its typical natural habitat is glades, rocky bluffs, and upland prairies.[1][3] 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] References
