The rainbow eucalyptus (Eucalyptus deglupta), also known as the Mindanao gum or rainbow gum, is a tall, broad-leaved evergreen tree which grows up to a height of around 60 metres (200 feet) in its native habitats of the Philippines, Indonesia, Papua New Guinea, Seram, Sulawesi, and Mindanao. The trunk of the tree, with a diameter of around 1.83m (6ft), is noted for its multi-hued appearance in summer. The smooth, orange-tinted trunk bark peels off in summer, revealing a plethora of colours in the new bark layer, representing the colours of the rainbow. Rows of rainbow eucalyptus trees, with their vibrant barks with streaks of green, yellow, red, and orange colours, offer a spectacular sight in summer. However, outside their native range, the rainbow eucalyptus grows to a smaller height and displays fewer colours. The tree possesses 6-inch long lancet leaves which yield an aromatic powder when crushed and produces small, white flowers during the blooming season.
