Pin Oak is a member of the red oak group and has been widely planted for landscaping. Its leaves have 5 to 7 lobes with deep, U-shaped sinuses between the lobes.... The ‘Pin’ name refers to the thin, pin-like branchlets that often arise from the smooth bark of its branches. The orientation of the branches is one tip for identifying this tree from a distance. The lower branches often droop downward, the middle branches grow perpendicular to the trunk, whereas the upper benches point upward. Read more at Southern Piedmont Natural History.
