Quercus velutina (Black Oak)
Black Oak, Quercitron Oak, Yellow Oak, Smoothbark Oak, Yellowbark Oak, Quercus tinctoria
Quercus velutina (Black Oak) is a medium-sized to large deciduous tree with an irregularly rounded crown. The large leaves, 10 in. long (25 cm), feature 7-9 deeply incised lobes. Glossy dark green above and paler underneath, they turn brilliant shades of yellow, orange or brown in the fall. Inconspicuous yellow-green catkins appear in spring before or as the leaves emerge. They give way to solitary or paired elliptic acorns adorned with fringed cups that cover up to 1/2 of the acorn. They are a valuable source of food for small mammals and birds, including squirrels, white-tail deer, mice, voles and turkeys. The young shoots and large terminal buds are covered with a dense, gray pubescence. Deeply furrowed on mature specimens, the tannin-rich, almost black outer bark hides yellow to orange inner bark that produces bright yellow dye. Native to eastern and central North America, Black Oak is quite adaptable and grows on poor, dry, sandy and heavy clay soils in the wild. Black Oak is not extensively planted as an ornamental, but its fall color contributes greatly to the esthetic value of oak forests. Black Oak makes an excellent shade or lawn tree for large areas.
