Ramie, (also China Grass and Chinese Silk Plant), a perennial plant of tropical Asia, where it has long been cultivated for its fibers. The plant grows to six feet (1.8 m) tall and bears heart-shaped leaves. The leaves are highly nutritious and are used as livestock feed. The fibers make up the epidermis, the tough outer layer of the stem, and are cemented together by pectin, a tenacious gummy substance. Ramie is grown in southeastern Asia, Brazil, Egypt, southern California, and Florida.
Ramie is stronger than any other natural fiber. It is stronger when wet than when dry, is highly absorbent, and resists mildew. It is white, lustrous, and lintless. Ramie is used to make fabrics, rope, industrial thread, industrial twine, fire hose canvas, industrial packing, and paper.
Ramie is Boehmeria nivea of the nettle family, Urticaceae.
