The bark is a light grey color with very rigid and noticeable fissures. The leaves are green in color ranging from 5-8 inches in length, changing to a red-brown in the Autumn season. White Oaks will sometimes hold their dead brown leaves over winter, these leaves will fall out in the Spring with the new growth. The wood is pale brown in color, solid, heavy and durable. The acorns appear annually, they are cup shaped and are a shiny brown in color.
