Eucalyptus Facts
Eucalyptus tree is known as one of the tallest plants on the planet. There are over 700 species of eucalyptus that belong to the family Myrtaceae. Most eucalyptus species are evergreen plants. Besides in the form of trees, some species of eucalyptus develop as shrubs. Most species of eucalyptus are native to Australia, New Guinea and Indonesia. Eucalyptus is very important and highly exploited plant because of its wood and oil. Eucalyptus is commercially grown in tropical and subtropical areas all over the world. Since it absorbs huge quantities of water from the ground, eucalyptus can be used for draining of marshes. It can also eradicate malaria by destroying wet habitats which are required for development of mosquito's eggs. Unfortunately, drying of the soil negatively affects other plant species.
