Tulip Tree (liriodendron Tulipifera)




Distinguishing characters: There are four characters that stand out

conspicuously in the tulip tree--the *bud*, the *trunk*, the

persistent *fruit cups* and the wedged *leaf*.



The bud, Fig. 74, about three-quarters of an inch long, is covered

by two purplish scales which lend special significance to its whole

appearance. The trunk is extremely individual because it rises stout

and shaft-like, away above the ground without a branch as shown in

Fig. 73. The tree flowers in the latter part of May but the cup that

holds the fruit persists throughout the winter. The leaf, Fig. 75,

has four lobes, is nearly as broad as it is long and so notched at

the upper end that it looks different from any other leaf.









Form and size: The tulip tree is one of the largest, stateliest and

tallest of our trees.



Range: Eastern United States.



Soil and location: Requires a deep, moist soil.



Enemies: Comparatively free from insects and disease.



Value for planting: The tree has great value as a specimen on the lawn

but is undesirable as a street tree because it requires considerable

moisture and transplants with difficulty. It should be planted while

young and where it can obtain plenty of light. It grows rapidly.



Commercial value: The wood is commercially known as _whitewood_ and

_yellow poplar_. It is light, soft, not strong and easily worked. It

is used in construction, for interior finish of houses, woodenware

and shingles. It has a medicinal value.



Other characters: The _flower_, shown in Fig. 75, is greenish yellow in

color, appears in May and resembles a tulip; hence the name tulip

tree. The _fruit_ is a cone.



Other common names: _Whitewood_; _yellow poplar_; _poplar_ and _tulip

poplar_.
