Brand The Sweetgum is a large
tree, growing up to 100 feet tall. It has a straight
trunk,
up to three feet wide. Sweetgums grow in woods
and along streambanks and lakes. Young Sweetgums are
pioneer
plants, growing quickly and taking over a field. Sweetgums are easy to
identify by their leaves. Leaves are star-shaped with five
pointy lobes,
and a long stalk. Fully grown leaves are about six inches
long, and bright green. In the Fall, leaves turn
red. Copyright, Mark

Brand Sweetgums are aromatic,
meaning they have a pleasant smell. You can crush a leaf to
get a good sense of this. Bark of Sweetgums is gray
and has deep furrows
(little ditches). Sweetgum flowers are
tiny, greenish, and ball-like. They grow in
clusters. Fruits are spiky green
balls that turn brown with age. They are a little over an
inch wide, and dangle on a long stalk.
Each ball has prickly points that open to let seeds out. Two
winged seeds
come from each hole. Seeds are mostly spread
by the wind.

University Sweetgum fruits,
called "gumballs" by children, are often dropped in huge
quantities. Up to 50 seeds can be in one
fruit. Seeds are eaten by
many birds, chipmunks, and squirrels. Very young Sweetgum
trees are eaten by deer, rabbits, mice, and
beaver. Sweetgums grow with
many other trees, including Virginia Pine, Eastern White
Pine, Yellow Poplar, oaks, American Elm, Red Maple, Silver
Maple, hickories, Flowering Dogwood, American Sycamore,
Sassafras and Redbud. Sweetgums provide
cover
for many birds and mammals. Sweetgums have
relationships with some helpful mushrooms;
while other fungi, such as the Oyster Mushroom, are
parasites. Other pests include
caterpillars,
such as tent caterpillars and Luna Moths. Treehoppers also
eat the leaves of Sweetgums. Ruby-throated
Hummingbirds visit Sweetgum flowers for nectar. Though many animals
depend on Sweetgums for seeds, they don't begin producing
them for about 20 years. Erv Evans, NC State
