California Buckwheat
Eriogonum fasciculatumAlso known as Flat-topped Buckwheat, Eastern Mojave Buckwheat, Wild Buckwheat
California buckwheat is a resilient, drought-tolerant shrub that forms the backbone of coastal sage scrub and chaparral communities across the American Southwest. Its dense, needle-like leaves help conserve moisture, while its abundant clusters of white and pink flowers provide a vital nectar source for hundreds of native pollinator species. As summer dry spells set in, the blossoms dry to a rich, rusty copper color, painting the arid hillsides with warm autumn hues.
