Plants 30–150 cm. Corms sub-globose. Stems puberulent (at least distally, sometimes glabrous proximally). Leaves: basal and proximal cauline 1-nerved, elliptic- to oblanceolate-spatulate, 120–300 × 25–50(–55) mm, abruptly, gradually, or little reduced distally, essentially glabrous, weakly, if at all, gland-dotted.

Phyllaries in (3–)4–5 series, (erect or outer sometimes spreading-reflexing) oblong-obovate to broadly obovate (not bullate), unequal, glabrous or minutely puberulent, margins usually with relatively narrow, hyaline borders, apices broadly rounded. Florets 19–80; corolla tubes usually pilose inside, sometimes glabrous (Arkansas, Illinois, Missouri). Cypselae 4.5–6(–6.5) mm; pappi: lengths ± equaling corollas, bristles barbellate.

Liatris scariosa, called savanna blazing star, is a species of flowering plant in the genus Liatris, native to the US states of Maryland, North Carolina, Pennsylvania, Tennessee, Virginia and West Virginia. It is fire-adapted, and its seeds germinate if they detect chemicals from plant smoke. It is a perennial herb that grows in dry woods and clearings. The Latin specific epithet scariosa means shriveled.
