Gray oaks are large shrubs or small trees reaching a maximum height of 30 ft. Deciduous, leathery, oval leaves are dull, blue-green, sometimes turning crimson in fall. Low clump-forming shrub or small tree, sometimes medium-sized, with grayish foliage.

Of greatest size in moist canyons, Gray Oak is most common as a shrub in New Mexico. It is easily seen in the Chisos Mountains in Big Bend National Park. It is closely related to Arizona White Oak (Quercus arizonica), a larger tree with larger leaves and sunken veins. Common and scientific names describe the color of the foliage.
