Eucalyptus Deglupta

Eucalyptus deglupta is a tall tree, commonly known as the rainbow eucalyptus, Mindanao gum, or rainbow gum. It is the only Eucalyptus species found naturally in the Northern Hemisphere. Its natural distribution spans New Britain, New Guinea, Ceram, Sulawesi and Mindanao.

The unique multi-hued bark is the most distinctive feature of the tree. Patches of outer bark are shed annually at different times, showing a bright green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones.

In the present day this tree is grown widely around the world in tree plantations, mainly for pulpwood used in making paper. It is the dominant species used for pulpwood plantations in the Philippines.
