原生地・分布（英語）:

説明（英語）: Genus of about 60 species of erect, spreading, or prostrate annuals or short-lived perennials, often invasive, from a range of habitats, including wasteland and fields, in temperate and tropical regions worldwide. They have alternate, entire leaves, and bear large, upright or pendent, catkin-like cymes of numerous densely packed, small, red or green flowers in summer and early autumn. The flowers are followed by variously coloured seed heads. In frost-prone areas, use as summer bedding, or grow in containers or hanging baskets; they may also be grown as short-lived house-plants or in a temperate greenhouse. A. tricolor cultivars are best grown under glass in cool climates. In frost-free areas, use for summer bedding. A. caudatus and A. hypochondriacus cultivars are good for cut or dried flowers.

耐寒性（英語）: Half hardy.
