Sulphur flower buckwheat

Eriogonum umbellatum

Native, drought tolerant, low-growing woody perennial forb to subshrub with tiny yellow flower clusters, blooming May to September. Tolerant of drought, salinity, carbonates and infertile soils; 6.5 to 9.0 pH range. Common on dry well-drained soils of rocky slopes, valley bottoms, sagebrush deserts or mountain meadows; up to 12,000 ft. elevation. Excellent species for native pollinators, including being a larval host and nectar source for the Lupine blue butterfly. Leaves and associated insects are an important food for sage-grouse chicks.
