[ edit ] Description This large tree grows to 35 meters in height with a trunk diameter of up to one meter. A specimen on the campus of Stanford University has a trunk diameter of 10.5 feet. [ 1 ] The trunk generally divides into two or more large trunks splitting into many branches. The bark is an attractive patchwork of white, tawny beige, pinkish gray, and pale brown, with older bark becoming darker and peeling away.The large palmately lobed leaves may be up to 25 centimeters wide and have three or five pointed lobes. New leaves are a bright translucent green and somewhat woolly. The deciduous tree drops copious amounts of dry golden to orangish red leaves in the fall. The inflorescence is made up of a few spherical flower heads each around a centimeter wide. The female flower heads develop into spherical fruit clusters each made up of many hairy, maroon-red-woolly achenes . The dangling seed balls are attractive on the tree.The tough and coarse-grained wood is difficult to split and work. It has various uses, including acting as a meat preparation block for butchers . Many small birds feed on its fruit, and several mammals eat its twigs and bark. The pollen and the hairs on leaves and flowers can be allergens for some people. [ 2 ] The new leaves are susceptible to anthracnose canker , which by necessitating a side bud to become the new leader, can create the picturesque angling trunks and branches on older specimens.
