Abstract
Yellow-poplar (
Liriodendron tulipifera L.) occurs naturally throughout the eastern and central United States from southern New England west to Michigan and south to Florida and Louisiana. Because of its wide occurrence, yellow-poplar grows under a variety of climatic, edaphic, and biotic conditions. Combinations of these different environmental conditions are associated with several broad physiographic regions such as the central valleys, northern and southern Appalachians, Piedmont Plateau, and coastal plain.
