Description
Black eyed Susans are wildflowers theat grow in meadows or native plant gardens for a naturalized look. It is an upright annual (sometimes biennial or perennial) growing 30-100 cm (12- 39 in) tall by 30- 45 cm (12- 18 in) wide. It has alternate, mostly basal leaves 10-18 cm long, covered by coarse hair, with stout branching stems and daisy-like, composite flowers appearing in late summer and early autumn. In the species, the flowers are up to 10 cm (4 in) in diameter, with yellow ray-florets circling conspicuous brown or black, dome-shaped disc-florets.[1] However, extensive breeding has produced a range of sizes and colors, including oranges, reds and browns.[2] The genus name honors Olaus Rudbeck, who was a professor of botany at the University of Uppsala in Sweden and was one ofLinnaeus's teachers. The specific epithet refers to the trichomes (hairs) occurring on leaves and stems.[3]The roots but not seedheads of Rudbeckia hirta can be used much like the related Echinacea purpurea. It is an astringent used as in a warm infusion as a wash for sores and swellings.[citation needed] The Ojibwa used it as a poultice for snake bites[9] and to make an infusion for treating colds and worms in children. The plant is diuretic and was used by the Menominee and Potawatomi.[10][11] Juice from the roots had been used as drops for earaches.[12]
The plant contains anthocyanins.[13]
