原生地・分布（英語）:

説明（英語）: Genus of 2 species of rhizomatous, marginal aquatic perennials, one semi-evergreen and one deciduous, found in shallow water by streams and lakes throughout the N. hemisphere, particularly E. Asia. They have sheathed, radical, linear or strap-shaped leaves, which die off in autumn leaving a small basal tuft of foliage that develops the following year. In midsummer, insignificant flowers, resembling small horns, 5-7cm (2-3in) long, are produced laterally just below the tips of central, leaf-like flower stems. They are excellent foliage plants for the shallow margins of a pool, for a bog garden or sink garden, or for marshy areas. Some cultivars of A. gramineus are useful aquarium plants.

耐寒性（英語）: Fully hardy to half hardy. Acorus species are short-lived in an aquarium if the water temperature exceeds 22°C (72°F) for long periods.

栽培（英語）:

繁殖（英語）: Divide rhizomes at the beginning of the growing season and pot up, planting out only when established; repeat every 3-4 years to prevent congestion.
