California Buckwheat
Eriogonum fasciculatum
Field notes
Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.
