Learn more about sweetgum

Native to North America, sweetgum is a very ornamental tree that also procures excellent quality wood for furniture-making. It is also more familiar to many under the name liquidambar. It’s sometimes even written out “Liquid Amber tree”, which is also true in a way!

From its wood and fruits, a sap can be extracted, usually called sweetgum balsam or Peru balsam that the Cherokee Indians used as chewing gum and is today used in infusions for its capacity to sooth the respiratory system, fight diarrhea and reduce stress.

Sweetgum is also a true marvel in fall with its purple hues that set the garden on fire.

Note that if your sweetgum doesn’t bear fruit, this is probably because it is a sterile cultivar called Liquidambar styraciflua ‘Rotundiloba’ that was created specifically so that the fruits, which are very slippery when burst, would not lead to accidents on parkings or along roads.

Sweetgum never bears fruit before the age of 25 years.
