Description

Georgia oak is a rare deciduous red oak, native to the southeastern United States. It often grows shrubby in the wild and up to 50 feet tall. It is found on dry granite and sandstone outcrops of slopes of hills at 160-1,640 ft altitude. It is considered endangered in some areas.

This oak is tolerant of a variety of soils as long as they are very well-drained and does best in full sun. This is a good shade tree for a smaller yard.
