原生地・分布（英語）:

説明（英語）: Genus of about 500-600 species of sedge- or grass-like annuals and ever-green, rhizomatous perennials, found almost exclusively in wet habitats throughout tropical and subtropical areas, with a small number in cool-temperate regions. They are grown for their foliage and unusual inflorescences. The cylindrical, 3-angled, or winged, often leafy stems, bear grass-like, linear leaves. Terminal, usually linear spikelets of hermaphroditic flowers have leaf-like bracts beneath, which in most species give the inflorescence a typically umbrella-like form. Grow at the margins of a pool or in a bog garden. In frost-prone areas, grow tender species as houseplants, in a temperate greenhouse or conservatory, or as marginal plants in an indoor pool.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed in permanently moist seed compost in spring; hardy species in containers in a cold frame, tender species at 18-21°C (64-70°F). Divide both tender and hardy species in spring. Plantlets will develop on the leafy inflorescences of some tender species if they are placed upside down in water.

病害虫（英語）: Trouble free.
