Additional Information

The Hardy Rubber Tree is an adaptable, relatively trouble-free plant that makes for an excellent shade tree. Its sap can be harvested for rubber, but this is an expensive and complex process. The specific epithet (ulmoides) refers to the leaf shape of the Elm genus (Ulmus), which is similar to that of Hardy Rubber Tree leaves.
