Eriogonum nudum var. pubiflorum (Fremont's wild buckwheat) is a native California subshrub in the Polygonaceae family.
Fremont's wild buckwheat is a California native perennial found in northwestern California, the Cascade Range, Sierra Nevada, Sacramento Valley, San Francisco Bay Area, and southern coastal ranges in sandy or gravelly habitats at elevations of 50 to 2,200 meters. Flowering from June to October, this plant produces white or yellow flowers in open branching clusters 20 to 40 centimeters wide. Growing 3 to 8 decimeters tall with slender, glabrous stems, it forms an open, spreading habit. Its basal leaves are distinctive, with blades 1 to 4 centimeters long, tomentose on the underside and glabrous or woolly-tufted on the upper surface. The delicate, open inflorescence and soft-textured leaves make this wild buckwheat a characteristic species of California's dry, open landscapes.
