A tree native to Australia, known for its fragrant leaves, fast growth, and valuable wood, commonly shortened from eucalyptus.
From Greek 'eu-' (good, true) + 'kalypto' (to cover); named for the cup-shaped structure that covers the flower buds.
Eucalypts can grow as tall as a 30-story building in just 15 years, and koalas have evolved to digest their toxic leaves—a food so poisonous it would kill almost any other animal!
