Tuliptrees provide food in many forms for many animals. In fall and winter, young trees are browsed by whitetail deer and rabbits. The spring flowers provide nectar for ruby-throated hummingbirds. Tuliptree seeds, maturing in summer and persisting into winter, provide food for both birds and mammals, including finches, cardinals, quail, mice, red squirrels, gray squirrels, and rabbits.
Once plentiful in their natural habitat in eastern America, Tuliptrees, with their tall, straight trunks, lack of lower branches, and hard wood, were favorites of loggers for railroad ties and fence posts. George Washington planted Tuliptrees at Mount Vernon which are now 140 feet tall and Daniel Boone favored the wood of this tree for his 60-foot dugout canoe.
It has normal moisture requirements, and can withstand some drought in humid regions only.
The leaves alternate, 3 to 6 inches long with distinctive lobes, a flat base, and two ear-like tips. Leaves are light green in summer and bright yellow in autumn.
Flowers are tulip-shaped, 1-1/2 to 2 inches in diameter with 6 greenish-yellow petals, each with orange at the base.
May to June.
The fruit is a cone-like aggregate of long, narrow, winged seeds. They are held upward on the tree and remain long after the leaves have fallen.
Rate of growth refers to the vertical increase in growth unless specified differently. Rate, as is true for size, is influenced by numerous variables such as soil, drainage, water, fertility, light, exposure, ad infinitum. The designation slow means the plant grows 12” or less per year; medium refers to 13 to 24” of growth per year; and fast to 25” or greater.Manual of Woody Landscape Plants, by Michael Dirr.
