The Tulip Tree or Yellow Poplar is a member of the Magnolia Family? It is not related to the poplar of the genus Populus.
The Tulip Tree, or Liriodenron tulipifera, is taller than other forest trees. Although they normally reach heights of 150 feet (46 m), Tulip Trees of almost 60 m (200 ft) in height and 3m (12 ft) in diameter have been found.
Because the Tulip Tree grows fast and is resists diseases, it is one of the most useful of the North American hardwoods; its wood is most popularly used for furniture. It grows from Ontario, Canada southward to Florida and westward to Arkansas. It is the state tree of Tennessee and Indiana.
The deciduous leaves of this Tulip Tree may range from three to six inches ( 7.5 to 15 cm ) long. Its tulip-shaped flowers have six pedals that are greenish-white with an orange band at their bases. The tree's cone-shaped fruit contain winged seeds.
