Corylus cornuta californica
Although usually grown for their edible nuts (see Filbert, Hazelnut), includes very attractive ornamental shrubs or small trees. The plants have separate female and male flowers. Female blossoms are inconspicuous; male ones are showy, appearing in pendent catkins on bare branches in winter or early spring. Leaves are roundish to oval, with toothed margins. Thin branches as needed in late winter; remove suckers when you see them.Corylus cornuta californica
