Prairie blazing star is an herbaceous perennial in the Asteraceae (daisy) family. Often grown as an ornamental, prairie blazing star reaches a maximum height of 5 feet but usually 2-4 feet. The purple disc flowers arranged in heads, are crowded on a coarse, hairy, leafy stem and bloom from top to bottom. The bracts below the heads have long pointed purplish tips that distinguish it from other species. The prairie blazing star is native to the central and southeastern United States where it prefers moist to dry, well-drained soils with full sun exposure. It may also be found in damp prairies and tolerates poor soils, drought and heat conditions. It does not tolerate wet winter soils.
Grow this plant in full sun in average well-drained moist to occasionally dry soil. Perfect for home gardens in the back of the border or in groups for cottage gardens, rock gardens, naturalized areas and pollinator gardens. The flowers attract hummingbirds and butterflies and birds will eat the seeds.
