Tulip Trees (Liriodendron tulipifera), commonly known as the American tulip tree, tulip poplar, or yellow poplar, is the the tallest eastern hardwood. It is native to eastern North America from Southern Ontario and Illinois eastward across southern New England and south to central Florida and Louisiana. It can grow to more than 50 m (165 feet) in virgin cove forests of the Appalachian Mountains, often with no limbs until it reaches 25–30 m (80–100 feet) in height. It is fast-growing species.
The flowers are pale green or yellow (rarely white), with an orange band on the tepals; they yield large quantities of nectar. The American tulip tree is the state tree of Indiana, Kentucky, and Tennessee.
