This oak tree is in the white oak group and native to the eastern United States. Since it is commonly found on rockier terrain, it is not as tall as a Northern red oak nor as wide as a white oak, but it can still grow as tall as 70 feet. Its bark is the thickest of any eastern North American Oak. The flowers are about two to three inches long, yellow, and have short spikes on the pistillate flowers. The acorns are either in singles or pairs and are oval: green when still young and shiny brown when fully ripe. The wood is used for traditional furniture such as television stands and buffets, as well as railroad treads because of its good resistance to decay.
