About Blue Oak: The mystical Blue Oak is a medium-size, deciduous tree endemic to California, where it grows mainly in the foothills of the central part of the state. Blue Oaks feature a rounded, somewhat irregular crown, and can grow to heights of up to 70 feet tall, but usually max-out closer to 50 feet tall. The trunk is typically singular, and seldom more than 2 feet in diameter. The bark is thin and flaky. The canopy is compact, round, and supported by many crooked branches. Quercus douglasii takes its name from the blue-green color of its shallowly-lobed, thick and waxy leaves.
Blue Oaks grow in a Mediterranean-like climate, with hot, dry summers and cool, wet winters. In summer, midday temperatures in Blue Oak woodlands can exceed 100°F (38°C) for weeks at a time. The Blue Oak prefers drier sites and is extremely drought and heat tolerant — in fact, it is the most drought tolerant of all California’s deciduous oaks. Generally, Blue Oaks live for several hundred years. The oldest known specimen, in Sequoia National Park, is about 400 years old. Historically, this species has been valued by Native Americans, who relied on Blue Oak for food, medicine, dyes, utensils, games, toys, basketry, and construction materials.
