It is native to the Ouachitas of west-central Arkansas and eastern Oklahoma in the central United States, where it is found growing in habitats such as rocky ridges, bluffs, hillsides, weathered sandstone, and open woods.

Description
Liatris compacta grows from rounded corms, that produce hairless stems 22 to 50 centimeters (8.8-20.0 inches) tall. The flowers are in heads with 18-25 flowers per head, the heads are produced singularly or in clusters of 2 to 5 heads. The heads have large leaf-like bracts under them; the stems attaching the heads to the main stem are 3 to 25 millimeters (0.12-1.00 inch) long. The heads are arranged in loose spike-like or raceme-like collections. The basal and early cauline leaves have 3 to 5 nerves and are elliptic-lanceolate in shape; the basal foliage often withers before flowering. The foliage is hairless and may have faint glandular dots; the leaves are gradually reduced in size as they ascend near the tops of the stems. The seed are produced in cypselae fruits that are 5.5 to 8 millimeters long with feathery bristles.
