Quercus tomentella [Arroyo Grande]

Quite rare in commerce, this striking tree, to 30 ft tall or so and endemic to the islands just off the coast of southern California, has 4" adult leaves that look very much like Lithocarpus densiflorus -- rather glossy green, rounded ovals with most attractive pleats particularly visible on the silvery undersides. Prefers sun and dry summers but tolerates average garden conditions as long as the drainage is good. These make good street trees or specimens for the mid-sized garden. Frost hardy to the upper end of USDA zone 7.
