Liriodendron tulipifera
Overview
The Tulip Tree, also known as Yellow Poplar or Tulip Poplar, is one of the tallest and most distinctive hardwood trees in eastern North America. Despite its common name, it is not closely related to tulips. Instead, it is a member of the magnolia family and is named for its large, tulip-shaped flowers.
A signature tree of Appalachian forests, the Tulip Tree is known for its straight trunk, uniquely shaped leaves, rapid growth, and impressive height. In favorable conditions, it can become one of the largest trees in the forest canopy, making it a prominent and easily recognized species throughout the region.
