Basswood trees are characterized by tall, straight trunks and a deep wide-spreading root system that makes them less vulnerable to wind than many other species. The American basswood, scientifically described as Tilia Americana, is also renowned for its heavy foliaged crown that features dark green heart-shaped leaves that reveal more lightly colored glistening undersides when rustled by a breeze. The hardwood tree is well suited for growth in the fertile soils of the northeast United States, where it proliferates in great numbers as a favorite ornamental shade tree.
