原生地・分布（英語）:

説明（英語）: Genus of about 25 species of winter-dormant, rhizomatous perennials, grown for their flowers, occurring mainly in subtropical forest in Mexico and Central America. Each of the small, scaly rhizomes produces a single upright, spreading, or trailing stem, which may be either branched or unbranched. The simple, ovate, dark green leaves are opposite (sometimes in unequal pairs) or in whorls, have toothed margins, and are fleshy and usually hairy; the undersides are often red and less hairy. From summer to autumn, salverform flowers are borne singly, in pairs, or in cymes from the leaf axils. There are many cultivars, with flowers in a wide range of colours. In frost-prone areas, grow in containers or hanging baskets in a temperate greenhouse, or as houseplants, In frost-free areas, grow in a border.
