Liriodendron tulipifera

Liriodendron tulipifera L.

Tulip tree, Tulip poplar, Yellow poplar

Magnoliaceae (Magnolia Family)

Synonym(s):

USDA Symbol: LITU

USDA Native Status: L48 (N), CAN (N)

One of the tallest and most beautiful eastern hardwoods, with a long, straight trunk, a narrow crown that spreads with age, and large showy flowers resembling tulips or lilies. A tall, straight, deciduous tree, up to150 ft. tall (sometimes taller), tuliptree has a medium to narrow crown and distinctive, star-shaped foliage. The leaves are waxy and smooth, and dependably turn bright gold in fall. Showy, yellow-orange, tulip-like flowers are often missed because they are up 50 ft. or higher in the tops of trees. Cone-shaped seedheads remain after leaves have fallen.

Introduced into Europe from Virginia by the earliest colonists and grown also on the Pacific Coast. Very tall trees with massive trunks existed in the primeval forests but were cut for the valuable soft wood. Pioneers hollowed out a single log to make a long, lightweight canoe. One of the chief commercial hardwoods, Yellow Poplar is used for furniture, as well as for crates, toys, musical instruments, and pulpwood.
