    Swamp White Oak has during the last few decades become a popular tree in professional landscapes of parks, public properties, schools, universities, and such. It is medium fast to fast growing of about 1.5 to 2 feet/year and it does not develop a taproot, but has a fibrous system that makes it easy to transplant. It likes acid soil best of pH 6.0 to 6.5, and can get iron chlorosis if the soil is neutral; however, it can adapt to pH around 7.0 after awhile. It is sold by many larger nurseries and native plant nurseries. Its native range is from southern New England into much of New Jersey and Pennsylvania, Maryland, some of West Virginia & Kentucky, northern Missouri, southern and central Wisconsin, all of Illinois, Indiana, and Ohio, and southern Michigan, growing in swamps, bottomlands, and along watercourses. Its large acorn gets to about 1.5 inches long and are loved by wildlife. Its leathery leaves are 5 to 6 inches long x 2 to 4 inches wide with large, irregular, rounded teeth and the underside of the leaves are usually whitish from thick plant hair. The bark is gray or brown-gray with papery flakes or heavy scaly for a long time before eventually becoming deeply furrowed and dark gray-brown. It lives about 150 to 200 years.
