The Rainbow Eucalyptus (Eucalyptus deglupta) captivates with its vibrant leaves that display an array of iridescent hues from blue to purple. Its bark sheds annually, revealing a multicolored canvas of orange, green, and red. These striking features result from the presence of chlorophyll, carotenoids, and other pigments that enhance the tree’s photosynthetic efficiency and provide camouflage from predators. Ecologically, it provides shelter and sustenance for wildlife, sequesters carbon, and filters water. Culturally, the Rainbow Eucalyptus holds medicinal and architectural significance. Despite facing conservation challenges, efforts are underway to protect this arboreal masterpiece.
