説明（英語）: Genus of 30 species of annuals, perennials, and biennials found in open, sunny habitats on prairies and hillsides in W., C., and S. North America and South America. They bear entire, toothed, lobed, or pinnatifid, hairy leaves, produced in basal rosettes and alternately on the stems. Red, orange, or yellow, daisy-like flowerheads, with dark purple, brown, red, or yellow disc-florets, are borne on long stems. The numerous cultivars are bushy, leafy plants with brightly coloured flower-heads and a long flowering period. They are effective in a sunny border and are also good for cutting.
