Liriodendron tulipifera, which is also known as the tulip tree, American tulip tree, whitewood, fiddletree, and yellow-poplar, is the tallest eastern hardwood.  

Tuliptree has been valued as an ornamental since 1663. The tuliplike flowers and leaves are aesthetically pleasing. The flowers are also valuable nectar producers. The flowers from a 20-year-old tree produce enough nectar to yield 4 pounds (1.8 kg) of honey. Tuliptree was used medicinally in the late 1800's: a heart stimulant was extracted from the inner bark of the root, and a tonic for treating rheumatism and dyspepsia was extracted from stem bark.
