Polygonum californicum is a species of flowering plant in the buckwheat family known by the common name California knotweed.

Description

Polygonum californicum is an annual herb producing a slender, angled stem which grows erect to a maximum height near 40 centimeters. The narrow, pointed leaves are mostly located on upper branches of the stem. The leaves have fringed, bristle-tipped stipules attached to their bases. Solitary white or pink flowers occur in upper leaf axils.[5]
