This is live oak, Quercus virginiana.

Live oak is often associated with southern plantation homes, and is at the northern limit of its hardiness in the Washington, DC area. This specific tree is a seedling from the most northerly naturally occurring population of lives oaks in southeastern Virginia. Live oak is that state tree of Georgia, and can be grown in
USDA hardiness zones 7 through 10. Live oak is a shrubby to large and spreading, long-lived, nearly evergreen tree. Open-grown trees average 50 feet in height and 3 to 4 feet in diameter. The rounded crowns may span 150 feet or more. Acorns are in clusters of 3 to 5, are 0.75 - 1 inch long and covered 1/3 by the cap, which is bowl-shaped and warty. You can find live oak in the National Grove of State Trees.
