:''This article is about a plant whose common names include "Angel Wings" , "Heart of Jesus" and "elephant ear" For other uses for those terms, please see Angel Wing (disambiguation) and Heart of Jesus (disambiguation).'' ''Caladium'' 〔''Sunset Western Garden Book,'' 1995:606–607〕 is a genus of flowering plants in the family Araceae. They are often known by the common name elephant ear (which they share with the closely related genera ''Alocasia'', ''Colocasia'', and ''Xanthosoma''), Heart of Jesus,〔(Caladium bicolor )〕 and Angel Wings. There are over 1000 named cultivars of ''Caladium bicolor'' from the original South American plant.〔(Caladium bicolor )〕 The genus ''Caladium'' includes seven species that are native to South America and Central America, and naturalized in India, parts of Africa, and various tropical islands.〔(Kew World Checklist of Selected Plant Families )〕 They grow in open areas of the forest and on the banks of rivers and go dormant during the dry season. The wild plants grow to 15–35 inches (40–90 cm) tall, with leaves mostly 6-18 inches (15–45 cm) long and broad.〔Macbride, J. F. 1936. Araceae, Flora of Peru. Publications of the Field Museum of Natural History, Botanical Series 13(1/3): 428–486.〕〔Funk, V. A., P. E. Berry, S. Alexander, T. H. Hollowell & C. L. Kelloff. 2007. Checklist of the Plants of the Guiana Shield (Venezuela: Amazonas, Bolivar, Delta Amacuro; Guyana, Surinam, French Guiana). Contributions from the United States National Herbarium 55: 1–584〕 ==Cultivation and uses== Several species are grown as ornamental plants for their large, arrowhead-shaped leaves marked in varying patterns in white, pink, and red (somewhat resembling the unrelated coleus) and have been in cultivation in Europe since the late 18th century. The two forms most widely cultivated are called "fancy-leaved" and "lance-leaved". The former is the more commonly seen and is the traditional caladium of cultivation; the leaves are more heart-shaped. The latter has more lance-head-shaped leaves. Most Caladiums in cultivation grow to about 24 inches (60 cm) high and 24 inches (60 cm) wide, although dwarf varieties are now in cultivation. Numerous cultivars have been selected, most of them derived from ''C. bicolor''. Many are sold as ''C. × hortulanem'', a synonym for ''C. bicolor''.〔(davesgarden.com )〕〔(floridata.com )〕 The lance-leaved varieties are also derived from ''C. schomburgkii''. Caladiums grow from tubers and can be propagated by dividing the tubers. They are hardy only to USDA plant hardiness zone 10; in colder areas, they are typically grown as tender "bulb"s or as houseplants. During their growing season, they require moderate watering (damp, not soggy). Most varieties prefer partial to full shade, although sun-resistant varieties are now in cultivation. Approximately 98% of all caladium "bulbs" are from Lake Placid, Florida, in the United States. In recent years, many new varieties have become available through breeding and are now largely disease resistant. The bulk of "bulb" production is sold to pot producers, who in turn provide local nursery outlets with potted caladiums ready for immediate planting. Most "bulb" growers also sell direct retail via websites, shipping of "bulbs" takes place in the spring when temperatures permit ("bulbs" are subject to damage if temperatures are too low). In temperate areas, they should be lifted before the first frost. The corms are dried and stored for the winter when temperatures fall to 65 °F (18 °C), and stored moderately dry (not bone-dry) over the winter at temperatures between 56 °F (13 °C) and 61 °F (16 °C). All parts of the plant are poisonous. They should not be ingested and may irritate sensitive skin. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Caladium」の詳細全文を読む スポンサード リンク
