原生地・分布（英語）:

説明（英語）: Genus of about 40 species of annuals, perennials, and shrubs from diverse habitats in tropical and warm-temperate North and South America, some of which have become naturalized in many tropical and subtropical countries. They may be erect, spreading, or mound-forming in habit, and have oval to lance-shaped, mid-green leaves. In summer and early autumn, panicles of 30-50 small flowerheads form soft, rounded, brush-like clusters, varying in colour from bright blue or grey-blue to pink or white; they are attractive to butterflies. Ageratums are usually grown as annuals; use A. houstonianum and its cultivars for bedding or as edging in borders. They may also be grown in containers.
