説明（英語）: Genus of about 1,000 species of annuals, perennials, climbers, subshrubs, shrubs, and trees from mainly tropical and subtropical habitats, ranging from moist meadows to dry woodland. Most occur in South America, some in Africa, Asia, Australasia, and North America. Species from more northerly habitats are usually annuals or herbaceous perennials; those from the tropics are mainly woody. Only the perennials are cultivated. They have upright stems bearing alternate, simple, entire or toothed, stalkless leaves, and flat, corymb-like cymes of tubular, purple or reddish pink, rarely white flowerheads, becoming rust-coloured with age. Grow in a wild garden or mixed border.
