Arboretum Trees—Swamp White Oak

Quercus bicolor

Similar to Q. alba, swamp white oak is notable for its timber and ecological benefit. The wood is near indistinguishable to white oak, and both are praised for their quality and workability. In contrast to Q. alba, however, swamp white oak prefers lowlands and moister soils (it’s in the name!). Speaking of names, Q. bicolor‘s name is in referenced to the dual colors found on the upper and bottom portions of the leaves.
