Description

Gum bumelia is a deciduous shrub or small to medium tree that is found in the south-central USA and Mexico in the Sapodilla family. It naturally is found at the edges of woodlands, along streams and ponds, and in fencerows and abandoned pastures. The short branches form an oval crown and the tree may reach 45 feet tall and 30 feet wide. The branches often have thorns. The tree flowers in early summer with clusters of small white flowers in the axils of the leaves. Small fruits mature to black in the fall.

This tree does well in sun to part shade in any well-drained soils including rocky ones. It is rarely used in landscapes and may be hard to find. However, it can be utilized in a naturalized setting.

Insects, Diseases, and Other Plant Problems:  No serious problems.
