Genus:Liatris

Species:aspera

Family:Asteraceae

Rough Blazing-star is a perennial plant native to the daisy family, emerging from a corm. It typically thrives in the prairies, glades, and open areas of the eastern and central United States. This plant showcases vibrant spikes of purple composite flowers, blooming from late summer into fall, and is particularly attractive to butterflies.

It can adapt to a variety of well-drained soils but thrives best in acidic, sandy, or rocky conditions, ideally in full sun to partial shade. This species is well-suited for native gardens, butterfly gardens, rock gardens, or cottage gardens, making a striking addition to the middle or back of a border. Additionally, it can naturally establish itself in wildflower meadows.
