Rainbow Eucalyptus (Eucalyptus deglupta)

The Rainbow Eucalyptus (Eucalyptus deglupta) or Mindanao Gum is the only species of Eucalyptus tree 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!

Nope, no crazy abstract painter has put a paint brush to this tree

The unusual phenomenon is caused by patches of bark shedding at different times. The different colours are therefore indicators of the age of the bark: Freshly shed outer bark will reveal the bright green inner bark. This darkens over time and changes from blue to purple and then reaches orange and maroon tones.
