Swamp White Oak is a medium to large oak of moist bottomland and poorly drained sites in the northeastern and north-central United States, distinctive for its shaggy, peeling upper bark that contrasts sharply with the darker, furrowed lower trunk bark — giving rise to its species name 'bicolor.' Its large, sweet acorns are produced on long stalks and are among the most preferred of all oak acorns by wildlife. It is a long-lived, stately tree reaching over 500 years old in undisturbed bottomland forests.
