Is Eucalyptus a native species?
Eucalyptus is native to Australia and the neighboring islands of Timor and Indonesia. Though there are more than 700 species of Eucalyptus in the world, there are no wild relatives of Eucalyptus that occur naturally in the U.S. Some varieties of Eucalyptus have been introduced in the warmest regions of the U.S., most notably in California, Florida and Texas; and some of these have naturalized.
