Coast Buckwheat (Eriogonum latifolium) is a shrub-like perennial in the Buckwheat family (Polygonaceae). It has oval, wooly white-green leaves with small, pink and white flowers in round clusters at the ends of long, wooly stems. The flowers fade to an attractive copper color in the fall.

Also known as Seaside Buckwheat, it naturally grows on coastal bluffs and slopes, where it receives full sun and all of its water from fog and rainfall.

In the garden, plant Coast Buckwheat on rocky slopes, in crevices, or sunny rock walls. When planted in its natural range, it will not need additional summer water after its first year. Provide part shade and some supplemental water when planted away from the immediate coast.

Coast Buckwheat supports many pollinators, and is an important food source for butterflies and moths. Allowing the flower stalks to remain through winter provides seeds for hungry birds.
