It is placed in the subfamily Panicoideae, supertribe Andropogonodae, tribe Andropogoneae. It is a perennial rhizomatous grass native to east and southeast Asia, India, Micronesia, Melanesia, Australia, and eastern and southern Africa. It grows from 0.6–3 m (2–10 feet) tall. The leaves are about 2 cm wide near the base of the plant and narrow to a sharp point at the top; the margins are finely toothed and are embedded with sharp silica crystals. The main vein is a lighter colour than the rest of the leaf and tends to be nearer to one side of the leaf. The upper surface is hairy near the base of the plant while the underside is usually hairless. Roots are up to 1.2 meters deep, but 0.4 m is typical in sandy soil. ==Cultivation and uses == It is used for thatching the roofs of traditional homes throughout south-east Asia. It is planted extensively for ground cover and soil stabilization near beach areas and other areas subject to erosion. Other uses include paper-making, thatching and weaving into mats and bags. It is used in traditional Chinese medicine.〔(【引用サイトリンク】title=Imperata )〕 A number of cultivars have been selected for garden use as ornamental plants, including the red-leaved 'Red Baron', also known as Japanese blood grass. Young inflorescences and shoots may be eaten cooked, and the roots contain starch and sugars and are therefore easy to chew.〔(Imperata cylindrica - Plants For A Future database report )〕〔(Imperata cylindrica )〕 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「Imperata cylindrica」の詳細全文を読む スポンサード リンク
