The scientific name for Black Oak is Quercus Velutina Lam . They rarely are found on rich ground, but mostly present on ridges and dry plains. The form of the leaves vary with about five to seven lobes, which may be divided until the mid rib. The lobes have teeth that taper from a base that is broad. The unfolding leaves turn from red to silver and then to green in early spring, and are 4 to 10 inches long, which have an ovate or obovate shape. The leaves are narrow, shallow and the ending is rounded with bristly teeth. The tree wood is used for commercial purposes like landscaping and easily available in a nursery, where for easy, quick and much mature sizes you should purchase Ball & Burlap trees.

Old black oak tree barks are black, thick and divided into deep round, broad ridges. The inner bark is pink in young black oak trees as compared to orange or yellow in the older ones. The Black Oak Q Nigera is commonly found in the Midwestern and eastern United States . It is also known as quercitron, yellow oak, smooth bark oak or yellow bark oak, and tastes and smells very bitter. This tree grows best in rich, well-drained, moist soils but can also survive in dry sandy, poor, heavy glacial and clay hillsides too. The life span of this tree is more than 200 years.

Black Oak Q Nigera can resist fire to an extent as long as there is no wound to its basal (which is quite thick). Small black oak trees that are wounded in fires grow back from the root crown. The twig is gray-green to red-brown and hairy if they have grown rapidly. The bud is around 0.25 to half an inch long and is pointed, angular, fuzzy and buff-colored. Unlike the Bald Cypress, this tree is not planted for ornamental purposes, but one cannot deny the aesthetic value. It also provides food for the squirrels, turkeys, mice, voles and other birds.

Black Oak can grow up to 100 feet in height with a diameter of 2-3 feet. Its wood is inferior when compared to the red wood because it cracks, as it is not tough, though it is hard and strong. The inner bark is for yellow dye and tannin. The acorn (fruit) is not edible as it is very bitter and poisonous for animals (though it does not prove to be that fatal for humans, it should not be considered as a food source) and is 1 inch long with a nut in light brown. The scales are flat and not swollen. The cup does not have a stalk or a fringe and usually covers half of the nut.

Black Oak Q Nigera does not allow grass to grow near it because of the shade, and its competition with the tree roots to get sufficient water to thrive on, besides this the soil gets acidic because of the tree.
