Tulip Poplar is a common and very large native deciduous tree. It is not a poplar but is in the magnolia family. Another species (Liriodendron chinense) is found in China and was introduced into the U.S. by Ernest Wilson in 1901. The curious green tulip-like flowers are striped orange. It is an important timber tree and Tuliptrees 200 feet tall once grew in rich Appalachian cove forests.
