Eriogonum wrightii Torr. ex Benth.
Perennial buckwheat, Wright buckwheat, Wild buckwheat, Bastard sage
Polygonaceae (Buckwheat Family)
USDA Symbol: erwr
Wild buckwheat is a woody shrub, 2–3 feet tall, with several slender branches. The whole plant is gray. At ground level it is surrounded by a thick mat of white, woody leaves about 1 inch long, but those along the stem are narrow and inconspicuous. The white, tubular flowers are in clusters, usually attached directly to the stem along the upper 2 inches, though some are scattered lower on the branches. Each flower has reddish sepals and bracts and a red stripe on the underside of the petal. In cool weather the flowers turn reddish-orange. The plants are found in association with juniper and sagebrush.
The species name of this plant is for Charles Wright, 1811-1885, world-wide botanical collector but mainly in Texas (1837-1952), Cuba and his native Connecticut.
