This rustic specimen may have multiple trunks no more than two feet in diameter. Numerous large, crooked branches are evident.
Leaves are small ovals two inches long, with wavy margins.
These leaves do not last the winter, falling off in autumn with a show of colors that range from orange to yellow. In spring the Blue Oak will show a light cover of new leaves. By summer, this foliage will be blue-green. The leaf canopy may extend outward to fifty feet. The Blue Oak often reaches a height of fifty feet with equal width and may become centuries old.
