The mindanao gum ranks among the world's tallest trees, reaching heights of over 200 feet. Even in cultivation it can reach over 100 feet. The common name derives from the large southern island in the philippines where it is native. It has an irregular to columnar open crown, with a small number of branches. The bark is the most striking feature of the tree, purple, orange or maroon, with a bright green underbark exposed as patches of old bark fall away. Leaves are opposite, smooth, ovate in shape, pale green in color, up to 6 inches long and contain an aromatic oil, obvious when the leaf is crushed. Flowers are borne in terminal or axillary clusters, blooms are tiny, having many stamens up to 1/2 inch long. Fruits also occur in clusters and are small rounded brown capsules about 1/4 inch in diameter and containing multiple very small seeds. The tree is propagated from seed. Mindanao gum is a commercial timber tree and energy tree and is grown across the world in short-rotation plantations. The leaf oil is not commercialized because the content is small. The tree grows well in a range of soils providing they are well-drained. In landscape use it obviously needs large open areas in parks or gardens, where as a specimen tree it can provide light shade and very showy bark and flowers.
