Sulphur-Flower Buckwheat

Sulphur-flower buckwheat is a variable, mat-forming perennial native to dry, open habitats across western North America, from rocky slopes to subalpine meadows. In Oregon, it is found mostly east of the Cascades, but grows well in well-draining soils and open sites in our region. It is easily recognized by its clusters of bright yellow, sometimes aging to orange or red, flowers held above silvery-green, spoon-shaped leaves. Blooming from late spring through summer, it provides vital nectar and pollen for native bees, butterflies, and other pollinators. Adapted to well-drained, often poor soils, sulphur-flower buckwheat is both drought-tolerant and erosion-resistant, making it an excellent choice for native restoration and xeriscape plantings, as well as rock gardens and green roofs.
