原生地・分布（英語）:

説明（英語）: Genus of about 30 species of evergreen perennials found in tropical forest in North and South America and the West Indies. Most cultivars are derived from D. seguine, now thought to include D. maculata, a name still used commercially. They are grown for their handsome, large, mainly paddle-shaped, oblong, or ovate, fleshy leaves, often heavily marked yellow or white and borne on sheathed stalks. As the lower leaves are shed, scars are left on the erect, thick, cane-like stems, although some modern cultivars are virtually stemless. Inflorescences with creamy spathes are produced intermittently throughout the year, although seldom in cultivation. In frost-prone areas, grow in a warm greenhouse or conservatory, or as houseplants; elsewhere, grow in a border. All parts may cause severe discomfort if ingested, and contact with sap may irritate skin.

耐寒性（英語）: Frost tender.

栽培（英語）:

繁殖（英語）: Root tip cuttings in spring or summer, or take stem sections, each with a growth bud, and lay flat on the surface of the compost. Alternatively, increase by air layering.

病害虫（英語）: Soft new growth is susceptible to infestation by aphids.
