The pin oak is a large, beautiful tree that grows up to 70 feet tall and can reach two feet in diameter. It commonly has a strong, upright single stem with numerous long, tough branches. The lower branches tend to droop, the middle ones are more horizontal and the upper ones are ascending. This gives the tree a pyramidal shape, and the many small, bristling twigs and branches give the tree its name. The pin oak is found widely over the east central United States.
