A moderate-to-fast-growing, long-lived tree with the largest leaves and acorns of all the oaks. Leaves turn brown or light yellow in the fall. Trees are weakly pyramidal when young then develop a massive trunk and broad crown with strong branches. Red-banded hairstreak butterfly caterpillars feed on decaying sumac leaves and oak litter, and oaks provide food and shelter to a wide range of wildlife.
