The Rainbow Eucalyptus (Eucalyptus deglupta) or Mindanao Gum is the only species of Eucalyptus found in the northern hemisphere. As if that weren’t extraordinary enough, the up to 70-m tall tree also shines in the colours of the rainbow: its bark can take on a yellow, green, orange and even purple shading!Now, this tree is cultivated widely around the world, mainly for pulpwood used in making paper. It is the dominant species used for pulpwood plantations in the Philippines.
This tree is also grown for ornamental purposes, due to the showy multi-coloured streaks that cover the trunk. Patches of outer bark are shed annually at different times, showing the bright-green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones
