Sulphur-flower buckwheat is a native, low-growing, woody perennial in the buckwheat family (Polygonaceae). The plant typically forms low, broad mats with individual clumps ranging from 4 inches to 2 ft (but up to 4 ft) tall and wide. Leaves are basal, 1 inch long, and softly wooly or hairless. Flower stems are 3 to 16 inches tall and topped by umbel-shaped clusters of tiny flowers. Flowers range from sulfur yellow to orange or reddish, sometimes turning rusty orange-red with age. Floral displays can color entire slopes starting in June at lower elevations and continue into September or October at higher elevations.

Pollinators: Sulphur-flower buckwheat attracts a wide variety of bees and other native pollinators.
