Rainbow Eucalyptus (Eucalyptus deglupta) trees, native to Southeast Asia, look like something from a fairytale. Their beautiful trunks are a result of how their bark grows.
As the trees grow, they shed flakes of bark, revealing bright green, young bark underneath. Slowly, this fresh bark ages and fades though a variety of colours – blue, purple, pink, orange, and finally a dark maroon colour. This final dark coloured bark falls away, repeating the cycle.
