Fallopia convolvulus (black-bindweed or wild buckwheat) is a fast-growing annual flowering plant in the family Polygonaceae native throughout Europe, Asia and northern Africa. It is an arable plant.
Synonyms include Polygonum convolvulus L. (basionym), Bilderdykia convolvulus (L.) Dumort, Fagopyrum convolvulus (L.) H.Gross, Fagopyrum carinatum Moench, Helxine convolvulus (L.) Raf., Reynoutria convolvulus (L.) Shinners, and Tiniaria convolvulus (L.) Webb & Moq. Other old folk names include bear-bind, bind-corn, climbing bindweed, climbing buckwheat, corn-bind, corn bindweed, devil's tether, and wild buckwheat.
Black-bindweed is a herbaceous vine growing to 1–1.5 m (39–59 in) long, with stems that twine clockwise round other plant stems. The alternate triangular leaves are 1.5–6 cm long and 0.7–3 cm broad with a 6–15 (–50) mm petiole; the basal lobes of the leaves are pointed at the petiole. The flowers are small, and greenish-pink to greenish white, clustered on short racemes. These clusters give way to small triangular achenes, with one seed in each achene.
While it superficially resemble bindweeds in the genus Convolvulus there are many notable differences; it has ocrea (stipule-sheath at nodes), which Convolvulus does not; and Convolvulus has conspicuous trumpet-shaped flowers while Black-bindweed has flowers that are unobtrusive and only about 4 mm long.
Fallopia convolvulus grows most commonly on disturbed or cultivated land, in northern Europe typically on warm, sunny, well-drained sandy or limestone soil types, but in hotter, drier areas like Pakistan, on moist shady sites. It ranges from sea level in the north of its range, up to 3600 m altitude in the south in the Himalaya.
