説明（英語）: Genus of 40 species of annuals, herbaceous perennials, subshrubs, and evergreen shrubs. Originally a genus of over 1,000 species, most have now been transferred by botanists to other genera, including Ageratina and Bartlettina. They occur in temperate, subtropical, and tropical regions in Europe, Africa, Asia, and North to South America, in habitats ranging from dry, sandy sites in woodland and thickets, to pastureland and swamps. They produce opposite, whorled, or alternate leaves, which are usually toothed and dissected, but sometimes entire. Tubular, bisexual, white, pink, violet, or purple flower-heads are borne in terminal or axillary corymbs or panicles, or occasionally singly. Most eupatoriums have nectar-rich flowerheads that are attractive to bees and butterflies. Many of the hardy species are coarse perennials, useful for a border or a wild or woodland garden. The shrubs and subshrubs are suitable for a mixed or shrub border, but need a warm, sunny site in cool climates. In frost-prone areas, grow tender species in a cool or temperate greenhouse or conservatory.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed of hardy species in containers in a cold frame, and seed of tender species at 13-16°C (55-61°F), both in spring. Divide hardy species, and root softwood cuttings of tender species, in spring.

病害虫（英語）: Whiteflies and red spider mites may be a problem under glass. Outdoors, slugs and aphids may be troublesome.
