Botanical Name: Baccharis pillularis Coyote Bush Dwarf Native to northern California Coast. A very dependable hardy, evergreen groundcover. Leaves are small, toothed, closely set on branches, about 1/2 long. Makes a dense bright green mat that is very adaptable to many types of conditions. Low maintenance.
Eriogonum latifolium or "Seaside Buckwheat" Eriogonums are very popular with butterflies and bees. Specifically mentioned were Hairstreaks and Acmon blues, which use Buckwheat (especially E. nudum in my area), as a host plant.
