Leaves: basal and proximal cauline 1-nerved, elliptictooblanceolate-spatulate, 120–300 × 25–50(–55) mm, bruptly, gradually, or little reduced distally, essentially glabrous, weakly, if at all, glanddotted.Heads in racemiform arrays. Peduncles usually (ascending) 10–50 mm.
Involucres campanulate to turbinate-camanulate, 11–15 × (12–)15–22(–25) mm.
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.

Stems with 8–20(–25) leaves or leafy bracts proximal to heads. Leaves: basal and proximal cauline elliptic- to oblanceolatespatulate, mostly 100–280 × 16–40(–45) mm, glabrous (weakly, if at all, gland-dotted). Heads usually 19–30.Florets 19–33.Flowering Aug–Sep(–Oct). Rock ledges, shale banksand barrens, limestone and sandstone outcrops, road banks, flood plains, dry woods; 600–1600 m; Md., N.C.,Pa., Tenn., Va., W.Va.Variety scariosa is an Appalachian entity that might justifiably be treated as distinct from ars. novae-anglieae and nieuwlandii at species level, as done by Shinners. It has shorter stems and smaller heads than vars. nieuwlandii and novae-angliae, and the transition in shape and size from basal to cauline leaves is more

Regularity: Regularly occurring
Easily grown in average, dry to medium, well-drained soils in full sun. Somewhat tolerant of poor soils. Prefers dry, sandy or rocky soils. Will grow taller in fertile loams, but may need staking. Intolerant of wet soils in winter. Tolerant of summer heat and humidity. May be grown from seed, but may take several years to establish. Plants may self-seed in the garden in open areas.
