A common cultivated plant of Asian origin, frequently escaped to disturbed ground, such as roadsides, fields, and railroads and first collected in 1880 in Kent Co., but hardly well established.
The achenes are the source of buckwheat flour, and buckwheat honey is made from the flowers. Fagopyrum tataricum (L.) Gaertn., another Asian species introduced in Europe and North America, was collected long ago at Corunna, Shiawassee Co., but may well have been cultivated there. In this species the perianth is less than 2 mm long and the achenes are rough or tuberculate on the sides; in our common buckwheat, the perianth is ca. 2–4 mm long and the achenes are smooth.
