Eucalyptus deglupta
Definition
Eucalyptus deglupta, known as the rainbow eucalyptus or bagras, is a fast-growing rainforest tree famed for its trunk, which sheds bark in patches to reveal streaks of green, orange and purple. It is the only eucalyptus native to the Philippines and the only one naturally found in the Northern Hemisphere.

Also Known As
Rainbow eucalyptus; bagras; Mindanao gum.
Examples and Analogies
The trunk has been compared to a constantly repainted canvas or living camouflage, and among Philippine trees bagras plays the role of a botanical celebrity, the way the balete or narra anchors folk heritage, but through pure visual spectacle.
Usage Scenarios
In Mindanao the species is grown in fast-rotation plantations for pulpwood and reforestation projects, while in parks and campuses across the tropics, including Hawaii where it is iconic along roads, it is planted purely as an ornamental avenue tree.
Strategies
Foresters value its extremely rapid growth for tree farms, manage it in short cycles, and protect remaining wild stands in lowland rainforest as genetic reservoirs.
Security and Safety Measures
Plantation managers plan fire breaks with care because eucalyptus oils and bark litter burn readily, and mature trees are given wide spacing from structures since tall specimens shed branches.
Historical Context
The species was described from Philippine material in the 19th century, with wild populations centered in Mindanao and extending into eastern Indonesia and New Guinea; its planted spread across the tropics made it one of the country’s most photographed trees abroad.
Challenges and Controversies
Debate surrounds eucalyptus plantations generally, including water use and effects on native forest, while in the Philippines wild bagras populations have shrunk with lowland deforestation.
