Another gem tracing its origins in American horticulture to the Cheyenne Experiment Station, this nearly perfect small tree has gorgeous bark, foliage and flowers followed by glistening red fruit in fall beloved of birds. Did we mention golden fall color? An underutilized tree, although treasured by keen gardeners in the Front Range.
