Comment:

The Liquidambar styraciflua tree may be the bane of some homeowner’s existence because of their troublesome fruit.  In his entry of the widely recognized Dirr’s Hardy Trees and Shrubs, Michael Dirr states “This lovely tree would be on every gardener’s wish list were it not for the woody, spiny, capsular, 1" to 1  ½" diameter fruit, which abscise through fall and winter.” 

The tree is a moderate to rapid grower and highly resistant to insect attack, making it a good candidate for reforestation and land reclamation projects.  Reaching typical heights of 60 to 80 feet it is not uncommon to find them exceeding the 100 foot mark.  These trees grow in a very straight form which makes it a good species for lumber, furniture, musical instrument components and veneer.  Other attributes of the Sweetgum include the ability to fix nitrogen in the soil and provide large areas of shade. 

Tree wood has been widely used for a number of applications including flooring, furniture and home interiors. The gum obtained from genus plants has been used in the past for a variety of purposes, including chewing gum, incense, perfumes, folk medicines and flavorings.

The common name of sweet gum refers to an aromatic balsam or gum that exudes from wounds to the tree.

Foliage:
Fall color at its best is a brilliant mixture of yellows, oranges, purples and reds.
Flower:
The Sweetgum has non-showy, monoecious, yellow-green flowers that appear in spherical clusters in April-May. Female flowers give way to the infamous gum balls which are hard, spherical, bristly fruiting clusters to 1.5” diameter.
