The unique multi-coloured bark is the most distinctive feature of the 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.
Rainbow Eucalyptus trees are cultivated around the world mainly for pulpwood creation purposes. Wood pulp is the most common ingredient when making paper, white paper that is. The pulp can be chemically or mechanically separated from the wood. It is a dry, fibrous material whose fibres disperse and become more pliable when suspended in water.
If you want to spot a Rainbow Eucalyptus tree live and in all its glory, you’ll have to travel to Indonesia, Papua New Guinea or the Philippines, the tree’s only native places. However, it has been introduced worldwide as an exotic wood in South America, Malaysia, Sri Lanka, China and other countries.
