hemp, common name for a tall annual herb (Cannabis sativa) of the family Cannabinaceae, native to Asia but now widespread because of its formerly large-scale cultivation for the bast fiber (also called hemp) and for the drugs it yields. Known and cultivated in ancient China, the plant was introduced into Europe before the Christian era. In the United States it was cultivated chiefly in the Midwest. The fiber, retted from the stem, was one of the most important for various kinds of cordage; it was also used in making paper, cloth (canvas and other kinds), oakum for calking ships, and other products. The male and female flowers are borne on separate plants. The chemical derived from the female flowering tops is used medicinally and is the source of marijuana marijuana or marihuana, drug obtained from the flowering tops, stems, and leaves of the hemp plant, Cannabis sativa (see hemp ) or C. indica; the latter species can withstand colder climates.

Stout, aromatic, erect annual herbaceous plant (Cannabis sativa, family Cannabaceae), the sole species of cannabis; also, its fibre. Hemp originated in Central Asia and is now cultivated widely in the northern temperate zone. A tall, canelike variety is raised for the fibre; a short, more branched variety is prized as the more abundant source of marijuana. Hemp fibre is strong and durable and is used for cordage and for artificial sponges and such coarse fabrics as sacking (burlap) and canvas. Hemp is grown primarily for fibre in most countries.
