Description
Distribution
Ecology
wooded-open ecotones of Cross Timbers that include oaks, ashes, elms, hickories (Gee et al 1994). Seen within their study plots of Midland Plateau Central Highlands where the surface soil texture is sandy clay loam with a clay subsoil; Hilly Coastal Plain and the Upper Loam Hills where the surface soils are loamy sands and the subsoils are sandy clay loams (Miller, Boyd, Edwards 1999).
Habitat
Phenology
“Hairy-stalked Silphium. This species has a perennial root; the stem four or five feet high, thick, solid, set with prickly hairs, and having many purple spots; the lower leaves alternate-upper opposite and sessile, rough, about two inches long, and an inch broad near the base, having a few slight indentures on their edges; the upper part of the stem divides into five or six small branches, terminated by yellow radiated flowers like those of the perennial Sun-flower, but smaller, having generally nine florets in the ray. Native of North America, flowering from July to September.” – Strong et al 1848 page 171
Seed dispersal
Seed bank and germination
