Species of white oak timber tree native to North America, found in eastern and midwestern United States and south-central Canada. It is also called "mossy-cup oak" for its heavily fringed acorn cups. It is a popular ornamental and shade tree in urban areas because of its resistance to insect and fungal attack, drought, and air pollution. Previously common in oak savannas and prairies, the tree is well adapted to fire with its corky, fire-resistant bark.
