Ecology & Life History

Basic Description: A bushy perennial herb with a short, heavy rhizome. Several scabrous stems grow erect from the base and are strongly winged between nodes. Leaves are opposite, with coarsely serrate or toothed margins. Ray flowers are spreading and yellowish colored; disk flowers are lacking (Kral 1983).
Technical Description: "Perennial. Stems solitary or 2 to several from a basal crown or short rhizome, slender, 4-8 dm tall, winged by decurrent leaf bases, sparsely short- and rough-pubescent, leafy below the inflorescence branches, opposite- or alternate-bracteate on those branches. Principal leaves opposite, sessile , oblong, elliptic-oblong, or oblong-oblanceolate, 3-8 cm long and 1-2(-3) cm broad, apices obtuse, margins bluntly low-toothed, surfaces scabrid. Heads few, radiate, borne terminally on bracteate branches. Involucres subhemispheric, 1-1.5 cm broad; bracts scabrid, imbricate in several series, lance-acute or -acuminate, medial ones 6-8 mm long. Ray flowers 5-10 per head, light yellow, ligules about 1.5 (-2) cm long, linear or lanceolate, mostly bifurcate apically; disc flowers few, corollas yellow. Achene obovate (including wings), 5 mm long, body dark brown, fusiform in outline, low-keeled, the wings purplish, narrow at base and broadening upwardly, at the summit even with and nearly obscuring a low, crownlike pappus" (Godfrey and Wooten, 1981).
Diagnostic Characteristics: Verbesina heterophylla is similar to V. chapmanii in rootstock and habit, but is distinguished by the following characters: leaves sessile, oblong, elliptic-oblong, or lanceolate; heads more numerous, usually single on numerous, upwardly arching, elongate stiffish stalks, narrower, between 1 and 1.5 cm broad; ray florets present, speading, yellowish; achene shorter, ca. 5 mm long, with a broader outline (Godfrey and Wooten, 1981; Kral, 1983).
Duration: PERENNIAL
Terrestrial Habitat(s): Savanna, Shrubland/chaparral
Habitat Comments: On sandy peat in fire-maintained savannahs or in open stands of slash pine-palmetto flatwoods where wiregrass dominates. (Based on Kral 1983.)
