  The largest of the California oaks, Quercus lobata eventually forms a massive tree to 60-70 feet tall and wide. This deciduous tree is primarily found in the interior valleys and the southern foothill regions of California. Its deep root system allows it to withstand long periods of drought. The California white oak can also handle extremely cold temperatures, according to Sunset Western Garden Book. USDA Zone 7.
