''Sarracenia leucophylla'', also known as the crimson pitcherplant or white pitcher plant, is a carnivorous plant in the genus ''Sarracenia''. Like all the ''Sarracenia'', it is native to the New World and inhabits moist and low-nutrient longleaf pine (''Pinus palustris'') savannas along the United States Gulf Coast, generally west of the Apalachicola River on the Florida Panhandle. The species is highly variable with respect to its pitchers, with plants in some localities reaching almost 1 metre in height, while in others, plants can be diminutive (such as the seldom seen 30 cm high dwarf form encountered at Garcon Point in Santa Rosa County, FL). ''S. leucophylla'' produces crimson flowers in the spring before its characteristically small spring pitchers. These are generally followed midsummer with flat non-carnivorous leaves known as phyllodia. Its most robust and handsome pitchers are then produced in the early autumn. It is one of the largest and showiest ''Sarracenia'' species, which has made it vulnerable to poachers as well as interest from the floral trade, in which the cut autumn pitchers often find use in arrangements. However, as is the case with most ''Sarracenia'' species, the greatest threat to ''S. leucophylla'' is loss of its unique wetland habitat to development along the Gulf Coast, as well as forest succession that was historically kept in check by fire. ''Sarracenia leucophylla'' has apparently been introduced by humans to areas outside its native range in North Carolina.〔(Weakley, Alan S. ''Flora of the Southern and Mid-Atlantic States Working Draft of 30 November 2012.'' )〕 In cultivation, ''S. leucophylla'' is generally less tolerant of stagnant water conditions and requires adequate soil drainage while still retaining requisite moisture levels to prevent root rot. Several clones are recognized: 'Schnell's Ghost', a yellow-flowered clone with little red in the pitchers (though not anthocyanin free); 'Hurricane Creek White', a group of predominantly white plants from Hurricane Creek, AL; 'Tarnok', a mutant form which produces a showy, although sterile, double flower; and 'Titan', an especially tall and robust form that may produce fall pitchers greater than 38 inches (97 cm) in height. Despite its native range in the southeast US, ''S. leucophylla'' is remarkably hardy and can be grown outside even in USDA zones 6 and colder with careful winter protection. image:Sarracenia leucophylla0.jpg|''Sarracenia leucophylla'' Image:Sarracenia leucophylla flower.jpg|''Sarracenia leucophylla'' flower Image:Sarracenia leucophylla field.jpg|Field of ''S. leucophylla'' Image:Sarracenia-leucophylla_wikimedia-org.png|''Sarracenia leucophylla in cultivation'' File:Sarracenia leucophylla Liberec 1.jpg| ''Sarracenia leucophylla'' at Liberec Botanical Garden, Czech Republic ==References== 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「Sarracenia leucophylla」の詳細全文を読む スポンサード リンク
