Kudzu (, also called Japanese arrowroot) is a group of plants in the genus ''Pueraria'', in the pea family Fabaceae, subfamily Faboideae. They are climbing, coiling, and trailing perennial vines native to much of eastern Asia, Southeast Asia, and some Pacific islands.〔 The name comes from the Japanese name for the plants, , which was written "kudzu" in historical romanizations. Where these plants are naturalized, they can be invasive and are considered noxious weeds. The plant climbs over trees or shrubs and grows so rapidly that it kills them by heavy shading.〔 The plant is edible, but often sprayed with herbicides.〔 ==Taxonomy and nomenclature== The name kudzu describes one or more species in the genus ''Pueraria'' that are closely related, and some of them are considered to be varieties rather than full species. The morphological differences between them are subtle; they can breed with each other, and introduced kudzu populations in the United States apparently have ancestry from more than one of the species. They are: *''P. montana'' *''P. lobata'' (''P. montana'' var. ''lobata'') *''P. edulis'' *''P. phaseoloides'' *''P. thomsonii''〔 (''P. montana'' var. ''chinensis'') *''P. tuberosa'' 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「kudzu」の詳細全文を読む スポンサード リンク
