Valley oak is an endemic species to California, thriving in the interior valleys and foothills from Siskiyou to San Diego counties. Once widespread, much of its native oak savanna habitat has been lost to development, making this iconic species increasingly scarce. Renowned as America’s largest oak, some specimens can reach up to 600 years old and 90 feet tall in the wild, though they seldom attain such size or longevity in urban settings. Its leaves emerge bright green in spring, with pale, fuzzy undersides that release an earthy aroma when crushed. Its latin name, lobata , refers to the deeply rounded lobes in its leaves.
