Polygonaceae (Buckwheat Family)

USDA Symbol: POHY2

USDA Native Status: Native to U.S.

Swamp Smartweed is a member of the buckwheat family (family Polygonaceae) which includes mostly herbs, sometimes shrubs or vines, rarely trees, with small flowers in racemes, spike-like clusters, or in heads. Stems commonly have swollen nodes. (The family name refers to this, deriving from Greek words meaning many knees.) There are about 40 genera and 800 species, chiefly in north temperate regions. Rhubarb and Buckwheat are sources of food, and a few species are grown as ornamentals.
