American Hornbeam (Carpinus caroliniana)
The American hornbeam can be found growing along streams in moist alluvial soils in the wild or as a shade tree in residential landscapes. The tree has distinct bark that has muscle-like fluting and is therefore sometimes also called musclewood. Its leaves are deep green, teardrop shaped, and sharply toothed. This tree attracts game birds, songbirds, and small mammals.
