Northern red oak
Northern red oak trees are found throughout the eastern United States, as far west as Kansas and as far south as Georgia. These trees can grow to up to 140 feet tall. The leaves of Northern red oaks have 7-9 pointed lobes with v-shaped sinuses (the indented part between the lobes). The bark of the Northern red oak is distinctive. It has dark red to grey-brown ridges with what appear to be shiny stripes down each ridge.
These trees have separate male and female flowers that appear in the form of catkins. Both male and female flowers can be found on the same tree. Acorns develop after the flowers have been pollinated but do not reach maturity (ripening) until the second year. Northern red oaks have been used in many revegetation projects following coal mining. The lumber from Northern red oaks is also commonly used in furniture making.
