They are perennials, surviving the winter in the form of corms.[5]

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.

Classification

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.[7][8] Liatris is closely related to Garberia, a genus with only one species endemic to Florida. The two genera can be distinguished by the shrub form of the latter and by karyotype.[9]

Species

Species in the genus include:[1][5][6][10][11][12]

gollark: - Most functions return `Result`s.- Outofbounds access, for example, can `panic` for not really handleable situations.- You can use the `?` operator which sticks in an early return (returning the errory thing, obviously) if it's an error or otherwise just returns the value of the `Ok`.- You can also do valid-result-or-panic with the `unwrap`/`expect` method.- Panics are isolated to threads.
