Description
The White Oak is a magnificent, long-lived canopy tree known for its massive spread, pale whitish-gray scaly bark, and durable timber. In spring, leaves emerge with a tender pinkish tone before turning bright green. They provide dense shade in summer and transform into striking coppery-brown or red tones in autumn, often persisting on the tree well into winter through marcescence.
Habitat
Found primarily in dry to moist deciduous forests, ridges, and uplands. Prefers well-drained acidic soils but is highly adaptable to various soil types in full sun to partial shade.
Native Range
Native to eastern and central North America, stretching from southern Quebec and Maine down to northern Florida, and westward to eastern Texas and Minnesota.
