Musclewood Quick Facts
• Musclewood is monoecious (male and
female flowers—both catkins—borne
separately on same tree). Flowers are
wind-pollinated. The fruit type is a nutlet.
• Leaves are alternately arranged, with sharply
double-toothed edges. Musclewood pro-
vides food for the larvae of the Eastern
Tiger Swallowtail and Red-spotted Purple
butterflies. Fall color is yellow, orange, or
red and not super showy on the straight
species—but cultivars offer enhanced color.
• One common name for Carpinus caro-
linana is blue beech, but the plant is in
the birch family (Betulaceae), not the
beech family. Another common name is
American hornbeam—not to be confused
with American hophornbeam (Ostrya vir-
giniana)—because musclewood is said to
"take polish" as readily as animal horns.
• Songbirds like yellow-rumped warbler
eat the tree's nutlets as do ruffed grouse,
squirrels, turkeys, and foxes. Black-capped
and Carolina chickadees nest in cavi-
ties of mature musclewood trees, and
wood thrushes build nests in the canopy.
Deer and rabbits occasionally browse
it, but it's not their preferred snack.
• Musclewood grows slowly and is rel-
atively short-lived, as it typically
senesces before reaching 100 years old.
Despite its dense wood, when it starts
to rot, it tends to decline quickly.
