The swamp white oak is native to the eastern United States but can tolerate our clay soils. Its leaf is interesting as it is bicolored, green on top and silvery beneath. In the fall this tree will turn golden-brown to russet-red and the leaves will persist throughout the winter. The acorns usually form in pairs on the branches and are edible to wildlife. The mature height will be up to 50 feet tall and up to 35 feet wide.
