Blue Oak

Blue Oak is a majestic native California tree prized for its striking blue-gray foliage and drought tolerance. This deciduous oak thrives in well-drained soils and full sun, making it ideal for water-wise landscapes and natural gardens. Reaching 40–60 feet at maturity, it provides excellent shade and wildlife habitat, supporting native insects and birds. Blue Oak develops a broad, spreading crown and displays beautiful fall color. Perfect for large properties, parks, and restoration projects, this climate-appropriate species requires minimal maintenance once established and adds year-round visual interest to any landscape design.
