Overview

Quercus douglasii, the Blue Oak, is a deciduous tree native to California's coastal ranges. Renowned for its bluish-gray leaves, this hardy oak thrives in dry, rocky soils, reaching 20-50 feet in height. Its canopy spreads 30-50 feet, providing dense shade and habitat value. Drought-tolerant once established, it's a low-maintenance choice for naturalistic designs, offering stunning fall color and acorns for local wildlife in USDA zones 7-9.
