Description
The White Oak is a magnificent, long-lived deciduous tree known for its broad, rounded crown and massive, sturdy branches. Its bark is light gray, scaly, and divided into shallow fissures. In spring, leaves emerge with a soft pinkish-gray fuzz before turning a vibrant medium green. In autumn, they transition to rich russet, dark red, or purplish tones, often persisting on the tree well into winter through a process called marcescence.
Habitat
Found primarily in deciduous forests, upland ridges, and well-drained slopes. Prefers acidic, moist, loamy or sandy soils, but is remarkably adaptable to various soil types and pH levels. Requires full sun to partial shade.
Native Range
Native to eastern and central North America, stretching from southern Quebec and Maine south to northern Florida and west to eastern Texas and Minnesota.
