distribution_en:

description_en: Genus of about 70 species of large, evergreen, mainly rhizomatous, some-times tuberous-rooted perennials, found in tropical forest and sunny, open or shaded, usually damp sites by streams and marshes in S. and S.E. Asia. They are cultivated for their large, usually peltate, heavily veined, oblong to ovate, arrow-shaped leaves, which are often marked in black, dark violet, or bronze, and have cylindrical leaf-stalks. The relatively insignificant spathes, borne at any time of year, are followed by clusters of red or orange fruits. In frost-prone areas, grow in a warm greenhouse; some species are suitable as houseplants. In frost-free areas, grow in a shady border. Contact with sap may irritate skin; all parts may cause mild stomach upset if ingested.

hardiness_en: Frost tender.

propagation_en: Sow seed at 23°C (73°F) as soon as ripe. Divide the rhizomes, or separate offsets, in spring or summer. Root stem cuttings in early spring.
