How to grow rainbow eucalyptus

Rainbow eucalyptus (Eucalyptus deglupta) is a tree unlike any other. It’s grown for its ornamental trunk, which has the unique property of changing color over time!

Rainbow eucalyptus is a brightly colored tree endemic to the Philippines, notably Mindanao Island. This species then expanded to French Polynesia, New Guinea, and New Britain, mostly for the purpose of making paper.

It is regarded as one among the world’s most beautiful trees.

Why a rainbow color?

The rainbow eucalyptus is unique in that it loses sections of its bark on a regular basis (and at various seasons), revealing a trunk that changes color over time.

Its trunk is a mosaic of hues, first pale green, then blue, purple, orange, and eventually brown, giving it the impression of a true rainbow! Although it appears as if a painter cleaned his brushes there, the colors are in fact natural.

“ Degluptere ” also means “to peel ” in Latin. Each tree sheds bark bits at a different rate, so each rainbow eucalyptus has different colored patterns. Likewise, each specimen sees its bark continuously changing color during its lifetime. A real delight for the eyes!

This tree is mainly cultivated for its decorative trunk . It is also used all over the world to make pulp. This eucalyptus variation is the only one (of of over 900 species) that does not generate essential oil.

Rainbow eucalyptus is very fast growing and can reach up to 75 meters tall! Its growth rate is about 3 m / year. It is adorned with white-yellow flowers gathered in panicles along the branches. Its leaves , oval in shape, are persistent.
