Conservation status: CNPS 1B.2

Prostrate buckwheat is a rare (CNPS 1B.2) California native perennial found in the Modoc Plateau in clay habitats at elevations of 1,400 to 2,700 meters. Flowering from May to July, this plant produces bright yellow flowers in compact heads 8 to 12 millimeters wide. Growing as a low-spreading mat to 10 to 30 centimeters in diameter, it forms delicate ground-hugging clusters with slender glabrous stems. Its basal leaves are small and woolly, ranging from 3 to 14 millimeters long and 1.5 to 6 millimeters wide, with a soft tomentose surface. The distinctive yellow flowers feature oblong to oblong-obovate perianth lobes, creating a subtle but charming ground-level display.
