Eriogonum Fasciculatum

California Buckwheat

Eriogonum fasciculatum — commonly called California Buckwheat — is a drought-tolerant, evergreen to semi-evergreen shrub valued for its long bloom season and adaptability to dry conditions. It forms a rounded, spreading plant with narrow, leathery gray-green leaves that are often white and woolly beneath, giving the plant a soft, silvery appearance. From late spring through fall, it produces clusters of small flowers that open white to pale pink and mature to rusty red, providing extended seasonal interest and excellent contrast against the foliage.
