Ghost gum, also known as white gum or smooth-barked gum, is a type of eucalyptus tree found primarily in Australia's arid regions. Its distinctive white, smooth bark has earned it its ghostly name. Other similar synonyms include ghostly gum, bone gum, moon tree, and white tree. Despite its nickname, the ghost gum is a living, breathing tree that can grow up to 30 meters tall and live for over 500 years. It plays a crucial role in Australia's ecosystem, providing shelter and food for various species of animals and insects. The ghost gum's beauty and resilience have also made it a popular subject for artists and photographers.
