Additional Information

One of the largest of shade trees, making massive, majestic specimens. Tolerant of urban conditions, but generally found in riparian areas in the wild. The mottled, multi-colored, exfoliating bark is very beautiful and makes for excellent winter interest. Needs a large volume of soil space. Anthracnose leaf and twig blight occasionally disfigure this tree, and can damage it severely. Leaves, twigs, bark, and fruit contribute to a significant litter problem. Although this species can tolerate urban conditions, it is generally not advisable to use as a street tree, due to the continuous litter produced and large space required.
