History/Lore

The live oak provides one of the most indelible images of the Old South. The huge branches of a live oak festooned with Spanish moss and spreading horizontally over grassy lawns is iconic. The tree has long been a favorite not only for its beauty and shade but also for its strong and dense wood. It was once so valuable for wooden vessels that the Navy maintained its own live oak forests. The early Native Americans liked it too, extracting an oil from its sweet acorns that was something akin to modern olive oil. It earned its place in American history as some of the lumber used in the construction of the naval frigate USS Constitution, and when British cannon balls bounced off the hull during a battle, the vessel was thereafter known as "Old Ironsides."

It is the state tree of Georgia.
