Eucalyptus Tree Facts



  • Eucalyptus trees make up a group of over 400 species of Australian trees. They grow fast and straight, and often reach tremendous heights.
  • Eucalyptus trees grow best in warm places that have alternate wet and dry seasons, such as Australia and the southern United States.
  • Eucalyptus trees have long, narrow, leathery leaves which are cut, pressed and then steamed to make eucalyptus oil.
  • In winter eucalyptus trees simply stop growing and produce no new buds.
  • Eucalyptus trees that grow in California originally come from seeds brought over from Tasmania.
  • Australians often call eucalyptus trees gum trees or just gums.
  • Eucalyptus leaves produce eucalyptus oil, which is used as a vapour rub for treating colds.
  • The most important tree grown for oil is the blue mallee or blue gum. Blue gum trees are the most widespread in North America.
  • Some eucalyptus trees give Botany Bay kino, a resin used to protect ships against worms and other animals that make holes in their hulls.
  • The jarrah is an Australian eucalyptus that gives a red wood rather like mahogany. Other eucalyptus woods are used to make everything from boats to telegraph poles.
  • Eucalyptus trees can grow to over 90 m tall — taller than any trees but Californian redwoods.
