Liriodendron tulipifera

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.

The flowers are pale green or yellow (rarely white), with an orange band on the tepals; they yield large quantities of nectar.

Native Americans so habitually made their dugout canoes of its trunk that the early settlers west of the Appalachian Mountains called it Canoewood.

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.

It is sometimes called "fiddle tree," because its peculiar leaves, with their arched bases and in-cut sides, suggest the violin shape.

[10] Today the tulip tree is one of the largest and most valuable hardwoods of eastern North America, thriving in temperate deciduous forests east of the Mississippi River.

[16] The Appalachian Mountains and adjacent Piedmont running south from Pennsylvania to Georgia contained 75 percent of all yellow-poplar growing stock in 1974.

This east central Florida ecotype/Peninsular allozyme group 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.

[20] All young tulip trees and most mature specimens are intolerant of prolonged inundation; however, a coastal plain swamp ecotype in the southeastern United States is relatively flood-tolerant.

The seeds typically travel a distance equal to 4–5 times the height of the tree, and remain viable for 4–7 years.

[22] In terms of its role in the ecological community, L. tulipifera does not host a great diversity of insects, with only 28 species of moths associated with the tree.

[23] Among specialists, L. tulipifera is the sole host plant for the caterpillars of C. angulifera, a giant silkmoth found in the eastern United States.

They show stronger response to fertilizer compounds (those with low salt index are preferred) than most other trees, but soil structure and organic matter content are more important.

[29] The southeastern coastal plain and east central Florida ecotypes occur in wet but not stagnant soils which are high in organic matter.

Most tulip trees have low tolerance of drought, although Florida natives (especially the east central ecotype) fare better than southeastern coastal plain or northern inland specimens.

Grown in the full sun, the species tends to grow shorter, slower, and rounder, making it adaptable to landscape planting.

[33] Liriodendron tulipifera has been introduced to many temperate parts of the world, at least as far north as Sykkylven, Norway and Arboretum Mustila, Finland.

While the heartwood is usually a pale green, it can take on streaks of red, purple, or even black; depending on the extractives content (i.e. the soil conditions where the tree was grown, etc.).

It is clearly the wood of choice for use in organs, due to its ability to take a fine, smooth, precisely cut finish and so to effectively seal against pipes and valves.

Used for interior finish of houses, for siding, for panels of carriages, for coffin boxes, pattern timber, and wooden ware.

It also has a reputation for being resistant to termites, and in the Upland South (and perhaps elsewhere) house and barn sills were often made of tulip wood beams.
