原生地・分布（英語）:

説明（英語）: Genus of 44 species of rhizomatous, submerged aquatic perennials from temperate and tropical regions of Africa, S.E. Asia, and N. and E. Australia. The linear to elliptic or lance-shaped, floating leaves are produced from a tuber-like rhizome. Compound panicles or simple, forked racemes of tiny, often scented flowers, with 1-6 tepals and 6 or more stamens, are borne, mainly in summer, from a spathe-like bract just above the water surface. Some species will grow in water to 1m (3ft) deep. A. distachyos and A. madagascariensis are the most commonly cultivated species and are suitable for a pond outdoors, although in frost-prone areas A. madagascariensis is best in an aquarium.

耐寒性（英語）: Frost hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed as soon as ripe, or seed that has been kept moist since collection, in small containers, covered by 5-7cm (2-3in) of water, at 13-16°C (55-61°F) for A. distachyos and 19-24°C (66-75°F) for A. madagascariensis. Divide rhizomes of large clumps when dormant.

病害虫（英語）: Young leaves are often eaten by water snails and the larvae of the brown china-mark moth. Algae may easily smother the delicate leaves of A. madagascariensis.
