Species of oak tree

Quercus georgiana, the Georgia oak or Stone Mountain oak, is a rare deciduous red oak, native to the southeastern United States.

Quercus georgiana is a small tree, often shrubby in the wild, growing to tall. It is classified in the red oak section Quercus sect. Lobatae.

The shiny green leaves are long and wide, with a petiole, and five irregular, pointed, bristle tipped lobes; they are glabrous (hairless), except for small but conspicuous tufts of hairs in the vein axils on the underside. The leaves turn dark red to brown in the autumn, stay on the tree throughout the winter, and fall as the new leaves bud in the spring.

Like all oaks, flowering and leaf out occur in late spring when all frost danger has passed. The flowers are monoecious catkins which, being self incompatible, require the presence of another oak for pollination. The acorns are round, long, maturing about 18 months after pollination.

Twigs are deep red, 1–2 mm in diameter and glabrous. Terminal buds are red brown, ovoid to subconic, 2.5–5 mm, and glabrous or with scales somewhat ciliate.

The bark is gray to light brown, scaly.

The Georgia oak is native to the southeastern United States, mainly in northern Georgia, but with additional populations in Alabama, North Carolina, and South Carolina. It grows on dry granite and sandstone outcrops of slopes of hills at altitude. Georgia oaks are also found at nearby monadnocks, including Panola Mountain and Arabia Mountain in Georgia.

It is occasionally cultivated as a specimen or garden tree in USDA plant hardiness zones 5–8. Besides landscape horticulture, the Georgia oak has no commercial uses.
