Description

'Oglethorpensis' Oak was first discovered in 1940 in Oglethorpe County, Georgia. It is an endangered species native to the southeastern United States and is threatened by land use changes, competition, and chestnut blight disease caused by Cryphonectria parasitica. Conservation efforts are currently underway to save the tree by people like the Morton Arboretum. Several arboretums have established the tree.

It is a medium to large-sized tree with a pyramidal to oval crown which becomes rounded with age. Lower branches often droop. The crown usually appears filled with sprouts and a dense growth of twigs. The leaves are similar to the Willow Oak in shape and turn red-brown in the fall and persist into winter. The natural habitat is moist clay soils in the piedmont area of southeast US.
