American hophornbeam, which loves hilly areas, has papery capsules containing nuts that are eaten by a variety of wildlife including grouse, bobwhite, deer, pheasant, rabbit and turkey. This tree has interesting reddish brown bark that is broken into narrow strips that are loose at both ends.

Its wood is very hard and is sometimes used to make tool handles. The tree has light brown heartwood and thick, white sapwood.
American hophornbeam was introduced into the landscape in 1690. The U.S. national champion is located near Grand Traverse, Mich., and is 74 feet tall with a 3-foot trunk.
American hophornbeam should be transplanted balled- and-burlapped or from a container in early spring. It is difficult to reestablish after transplanting. The tree's tap root can be cut in the nursery to give it a root structure to better fit a specific location. It can also be grown in containers or root-control bags.
