Sweet Gum Overview

A popular deciduous tree grown for their maple-like leaves with a serrated-margin, brilliant and long-lasting autumn colour. Their flowers and fruits are inconspicuous. It is often planted as an attractive border or hedge or to form beautiful avenues. It is a feature plant during autumn in any large garden providing shade in warm summers and allowing sun through bare branches in winter. After an injury to the stem, a red gum-like fluid appears that lead to the common name liquid amber.
