Golden buckwheat

Family: Polygonaceae · Type: annual · Native

Golden buckwheat is a California native annual found in dry, open grasslands and oak woodlands at low elevations. Flowering from June to September, this delicate plant produces white to rose or pale yellow flowers in small, clustered inflorescences up to 40 centimeters wide. Growing 20 to 60 centimeters tall with slender, straight stems that are typically glabrous, it forms an open, branching structure. Its leaves are primarily basal, with blades 5 to 50 millimeters long, often tomentose on the undersurface and varying from hairy to smooth on the upper surface. The tiny flowers, measuring 1 to 2.5 millimeters long, are arranged in neat involucres at the tips of delicate branchlets.
