Facts About

Tuliptree is easy to remember for its leaves, which are shaped roughly like tulip flowers with rounded bases and square-lobed tops. It is the largest member of the magnolia family in New England and one of the tallest hardwoods in eastern North America, with a tall, straight trunk reaching up to 200 feet (65m) in height. It produces showy, white flowers in spring. The lustrous, yellow wood gives this species its alternative common name, yellow poplar. The wood is very light and soft, and suitable for many uses including veneer, pulpwood, crates for holding water and food, and floating rafts. Its majestic, straight trunk and showy flowers also make it a popular ornamental tree.
