Description

The tulip tree is one of the largest of the native trees of the eastern United States, known to reach the height of 190 feet (58 m), with a trunk 10 feet (3 m) in diameter; its ordinary height is 70 feet (21 m) to 100 feet (30 m). It prefers deep, rich, and rather moist soil; it is common, though not abundant, nor is it solitary. Its roots are fleshy. Growth is fairly rapid, and the typical form of its head is conical.

The bark is brown, and furrowed. The branchlets are smooth, and lustrous, initially reddish, maturing to dark gray, and finally brown. Aromatic and bitter.
The wood is light yellow to brown, and the sapwood creamy white; light, soft, brittle, close, straight-grained. Sp. gr., 0.4230; weight of cu. ft., 26.36 lbs.
  • Winter buds: Dark red, covered with a bloom, obtuse; scales becoming conspicuous stipules for the unfolding leaf, and persistent until the leaf is fully grown. Flower-bud enclosed in a two-valved, caducous bract.

The alternate leaves are simple, pinnately veined, measuring five to six inches long and wide. They have four lobes, and are heart-shaped or truncate or slightly wedge-shaped at base, entire, and the apex cut across at a shallow angle, making the upper part of the leaf look square; midrib and primary veins prominent. They come out of the bud recurved by the bending down of the petiole

  • Calyx: Sepals three, imbricate in bud, reflexed or spreading, somewhat veined, early deciduous.
  • Corolla: Cup-shaped, petals six, two inches long, in two rows, imbricate, hypogynous, greenish yellow, marked toward the base with yellow. Somewhat fleshy in texture.
  • Stamens: Indefinite, imbricate in many ranks on the base of the receptacle; filaments thread-like, short; anthers extrorse, long, two-celled, adnate; cells opening longitudinally.
  • Pistils: Indefinite, imbricate on the long slender receptacle. Ovary one-celled; style acuminate, flattened; stigma short, one-sided, recurved; ovules two.
  • Fruit: Narrow light brown cone, formed by many samara-like carpels which fall, leaving the axis persistent all winter. September, October.


A description from Our native trees and how to identify them by Harriet Louise Keeler:

Distribution

Found sparingly in New England, it is abundant on the southern shore of Lake Erie and westward to Illinois. It extends south to north Florida, and is rare west of the Mississippi River. Its finest development is in the Southern Appalachian mountains, where trees may exceed 170 feet in height.

This east central Florida ecotype seems to have the best ability to tolerate very wet conditions, where it may grow short pencil-like root structures (pneumatophores) similar to those produced by other swamp trees in warm climates. Some individuals retain their leaves all year unless a hard frost strikes.

Liriodendron tulipifera produces a large amount of seed, which is dispersed by wind. The seeds typically travel a distance equal to 4-5 times the height of the tree, and remain viable for 4–7 years. The seeds are not one of the most important food sources for wildlife, but they are eaten by a number of birds and mammals.

The tulip tree has impressed itself upon popular attention in many ways, and consequently has many common names. In areas near the Mississippi River it is called a poplar largely because of the fluttering habits of its leaves, in which it resembles trees of that genus. The color of its wood gives it the name Whitewood. Native Americans so habitually made their dugout canoes of its trunk that the early settlers west of the Appalachian Mountains called it Canoewood.

Cultivation and use

The Liriodendron tulipifera tree grows readily from seeds, which should be sown in a fine soft mould, and in a cool and shady situation. If sown in autumn they come up the succeeding spring, but if sown in spring they often remain a year in the ground. Loudon

 family, they have fleshy roots that are easily broken if handled roughly. Transplanting should be done in early spring, before leaf-out; this timing is especially important in the more northern areas. Fall planting is often successful in Florida. The east central Florida ecotype may be more easily moved than other strains because its roots grow over nine or ten months every year—several months longer than other ecotypes.

, although Florida natives (especially the east central ecotype) fare better than southeastern coastal plain or northern inland specimens.

It is recommended as a shade tree. The tree's tall and rapid growth is a function of its shade intolerance. Grown in the full sun, the species tends to grow shorter, slower, and rounder, making it adaptable to landscape planting. In forest settings, most investment is made in the trunk (i.e., the branches are weak and easily break off, a sign of axial dominance) and lower branches are lost early as new, higher branches closer to the sun continue the growth spurt upward. A tree just 15 years old may already reach 40 feet in height with no branches within reach of humans standing on the ground.
