Sweet gum Overview

The Liquidamber genus containing 15 species of large deciduous trees of about 25-40 metres in the Altingiaceae family, native to Asia, Southeastern Europe and North America and Mexico. Commonly known as sweet gum, satin walnut or American storax, they are cultivated for their maple-shaped leaves that take on an ever-changing range of stunning and long-lasting autumn colours. The common name 'sweet gum' and the genus name 'Liquidamber' refers to the sweet, sticky sap that exudes from the trunk when cut. The hard, woody fruit is covered in prickly armour and is referred to as a gumball.
