Wikipedia Abstract

Quercus phellos (willow oak) is a North American species of a deciduous tree in the red oak group of oaks. It is native to the eastern and central United States from Long Island south to northern Florida, and west to southernmost Illinois, Missouri, Oklahoma, and eastern Texas. It is most commonly found growing on lowland floodplains, often along streams, but rarely also in uplands with poor drainage, up to 400 meters (1,300 ft) altitude.

Usage [3]  A mulch of the leaves repels slugs, grubs etc, though fresh leaves should not be used as these can inhibit plant growth; Oak galls are excrescences that are sometimes produced in great numbers on the tree and are caused by the activity of the larvae of different insects. The insects live inside these galls, obtaining their nutrient therein. When the insect pupates and leaves, the gall can be used as a rich source of tannin, that can also be used as a dyestuff; The bark contains about 10% tannin and is a commercial source of that material; Tannin is also found in the leaves and wood; The seedcups are used as buttons; Wood - close-grained, strong, not hard, heavy, not durable; It weighs 46lb per cubic foot; Of rather low quality for an oak but it is sufficiently abundant to be harvested commercially. The wood is used for construction, fellies of wheels and charcoal;
