Liatris (/laɪˈætrɪs/[2]), commonly known as gayfeather[3] and blazing star[4][5] is a genus of flowering plants in the tribe Eupatorieae within the family Asteraceae native to North America (Canada, United States, Mexico and the Bahamas).[6][7][4] Some species are used as ornamental plants, sometimes in flower bouquets. They are perennials, surviving the winter and resprouting underground corms.[4]
Liatris species are used as food plants by the larvae of some Lepidoptera species including the flower moths Schinia gloriosa and Schinia sanguinea, both of which feed exclusively on the genus, and Schinia tertia and Schinia trifascia.
Liatris is in the tribe Eupatorieae of the aster family. Like other members of this tribe, the flower heads have disc florets and no ray florets. Liatris is in the subtribe Liatrinae along with Trilisa, Carphephorus, and other genera.[8][9] Liatris is closely related to Garberia, a genus with only one species endemictoFlorida. The two genera can be distinguished by the shrub form of the latter and by karyotype.[10]
Species in the genus include:[1][4][5][11][12][13]
