Swamp White OakQuercus bicolor
Deciduous tree 50-60' tall and 40-50' wide with a trunk top up to 3' wide. Typically the crown is broad and rounded, often with drooping branches. Can withstand many stresses. It is used as a buffer slope and shoreline stabilizer. It is the only oak tree that is resistant to soil compaction. Its ability to withstand flooding suggests its use in rain water gardens as well as restorations of woodland swamps, flood plain forests, and other wet, forested, low areas. This species requires acidic soils. Excellent wildlife benefits, good in wet and low areas.
