Ecology & Life History
Help
Basic Description: Perennial herb with oval, long-stemmed basal leaves, feather-lobed stem leaves, and branching clusters of rather small, yellow, aster-like flowers.
Technical Description: Perennial, 3-8 dm tall from a rather short caudex, densely and persistently woolly at the base, otherwise soon glabrate except in the axils. Basal leaves mostly elliptic- oblanceolate, tapering to the petiole, crenate or serrate, up to 30 cm (petiole included) x 3.5 cm; cauline leaves deeply pinnatifid, reduced and becoming sessile upward. Heads numerous, commonly 20-100 or more, small, the disk 5-9 mm wide; involucre 4-6 mm high; rays 4-8 mm long. Achenes hispidulous on the angles. n = 22. (Cronquist 1980)
Diagnostic Characteristics: Plant perennial; principal leaves once-pinnatifid; persistently woolly at the base and sometimes in the leaf axils, but not on the upper stem, leaves, or incolucre; plant not stoloniferous; basal leaves tapering to the petiole; heads many, mostly 20-100 or more. (Cronquist 1980) Hybridizes with several other species including S. pauperculus (Fernald 1950), S. aureus, and S. plattensis (Uttal 1982), and (rarely) S. tomentosus (Chapman and Jones 1971.)
Duration: PERENNIAL
Reproduction Comments: Ray flowers pistillate and fertile, disk flowers perfect (Cronquist 1980). The genus is "a generalist with respect to pollination" (Schmitt 1980). Pollinators recorded for other Senecio species in North America include bumblebees (Bombus spp.) and various butterflies (Schmitt 1980); and for Senecio jacobea, a British species, 178 insects including thrips, Hemiptera, beetles, butterflies and moths, and many Hymenoptera and flies (Proctor and Yeo 1973). Persistent pappus serves to disperse achenes by wind.
Terrestrial Habitat(s): Forest/Woodland, Grassland/herbaceous, Savanna, Woodland - Mixed
Habitat Comments: Meadows, pastures, roadsides, dry woods, savannas, thickets, clearings. (Cronquist 1980, Fernald 1950, Radford et al. 1968)
