Although at first glance this tree might look as if it were painted, it is actually a natural species of Eucalyptus that grows in exotic places such as New Guinea and the Philippines. The Eucalyptus Deglupta, or more commonly known as the Rainbow Eucalyptus, has a unique bark which changes colour over time. When a patch of bark is shed, a bright green inner bark will show. Over time this will turn to blue, purple, orange and the maroon as it matures and hardens.

And for the colourful nature lovers, here’s another interesting phenomenon: the Caño Cristales, a Colombian river, which actually produces the same colours.

‘The River of Five Colours’, its more common name, is home to several species of algae. Most of the year these are green but during a short period in between the wet and dry season, when the water level is just right, the Macarenia Clavigera plant turns the river into this colourful sight.
