Rough Blazing Star (Liatris aspera) is an upright, clump-forming, perennial which typically grows 2-3 feet tall and which commonly occurs in dryish soils on prairies, open woods, glades, meadows and along roads and railroad tracks. Features rounded, fluffy, deep rose-purple flower heads (each ¾-inch across) which are crowded into long, terminal flower spikes atop erect, rigid, leafy flower stalks. Stalks arise from basal tufts of rough, very narrow, lance-shaped leaves (to 12 inch long). Flowers open somewhat at the same time, which makes this species a particularly good fresh cut flower for floral arrangements. The blooming period occurs from late summer to early fall and lasts about 3 weeks for individual plants. Like other Liatris spp., the flowers of Rough Blazing Star begin to bloom at the top of the flowering stalk, and gradually bloom downward as the season progresses. The achenes have large tufts of stiff hair that are light greyish brown, which enables them to be distributed several feet by the wind. The root system consists of a woody corm. Occasionally, offsets develop a short distance from the mother plant, creating small colonies.

Habitats include mesic to dry black soil prairies, sand prairies, gravel prairies, hill prairies, bald knobs, openings in rocky upland forests, sandy Black Oak woodlands, savannas, limestone glades, dry clay banks above ditches, and open areas along railroads, particularly where prairie remnants occur.

Easily grown in average, dry to medium, well-drained soils in full sun. Tolerant of poor soils, drought, summer heat and humidity. Intolerant of wet soils in winter.
