The unique multi-hued bark is the most distinctive feature of the tree. Patches of outer bark are shed annually at different times, showing a bright green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones. The previous season’s bark peels off in strips to reveal a brightly colored new bark below. The peeling process results in vertical streaks of red, orange, green, blue, and gray. The colours of the bark are not as intense outside the tree’s native range.
E. deglupta grows up to 2 m (6 ft) wide and over 60 m (200 ft) tall.
