Reynoutria multiflora (syn.Fallopia multiflora and Polygonum multiflorum) is a species of flowering plant in the buckwheat family Polygonaceae[1] native to central and southern China.[2][3] It is known by the English common names tuber fleeceflower[4] and Chinese (climbing) knotweed. It is known as he shou wu in China and East Asia.[5] Another name for the species is fo-ti,[6][7][8] which is a misnomer.[9]
It can be difficult to prevent the spread of this vining plant and to remove it once established. The leaves are thin and fragile but the stems, although narrow in diameter, can be very strong.
Reynoutria multiflora is a herbaceousperennialvine growing to 2–4 m (6 ft 7 in – 13 ft 1 in) tall from a woody tuber. The leaves are 3–7 cm (1.2–2.8 in) long and 2–5 cm (0.79–1.97 in) broad, broad arrowhead-shaped, with an entire margin. The flowers are 6–7 mm (0.24–0.28 in) diameter, white or greenish-white, produced on short, dense panicles up to 10–20 cm (3.9–7.9 in) long in summer to mid autumn. The fruit is an achene 2.5–3 mm (0.098–0.118 in) long.[2]
