The exquisitely colorful display on the bark of this tree has earned it the name rainbow eucalyptus (Eucalyptus deglupta).
When the bark slowly peels off layer by layer, the bright green surface found inside the tree gradually turns blue, then purple and finally brick red as it is exposed to air.
Although most Eucalyptus trees are native to Australia, this one originates from Papua New Guinea, the Philippines and Indonesia.
Often planted for its decorative effect, the rainbow eucalyptus is also harvested for paper pulp and construction material.
In the Philippines, the bark is pulverized for use in traditional medicine to reduce fatigue.
