Eriogonum fasciculatum

Common Names

California Buckwheat, Flattop Buckwheat, Flat-Topped Buckwheat, Eastern Mojave Buckwheat, Yellow Buckwheat

Summary

California buckwheat is a native southwestern evergreen shrub or subshrub with narrow, leathery leaves that are often fascicled and rolled under, and white-tomentose undersides; tiny white to pinkish flower heads form dense flat-topped clusters on long stems, blooming March–October, and it is highly drought-tolerant, serving as a nectar source for bees and a host plant for several butterfly species.

Care and cultivation emphasize full sun on well-drained soils, with minimal watering once established; propagation is by seed or cuttings, and plants can be pruned lightly after flowering or in late winter/early spring; uses include erosion control and habitat/listing for wildlife-friendly landscapes, with reinforced value as a nectar source for pollinators and general deer resistance and low maintenance.
