The History of Eucalyptus Trees
Eucalyptus trees are native to Australia, where they have been around for millions of years.

Today eucalyptus is grown in many countries for a variety of uses, including timber, paper pulp, and essential oil production.
Types of Eucalyptus Trees
Each species of Eucalyptus has unique characteristics, such as leaf shape, color, and scent. Some of the most common types of eucalyptus trees include:

One of the tallest eucalyptus species, Blue Gum reaches up to 60 meters high. It has grayish-green leaves with a distinctive aroma and produces white flowers in late winter and early spring. The tree's wood is highly valued for its strength and durability, making it suitable for construction and furniture making.
Red Ironbark (Eucalyptus sideroxylon)
Native to Eastern Australia, Red Ironbark is known for its hard, dense timber that is resistant to termites and decay. The tree gets its name from the deep red color of its bark, which flakes away to reveal a smooth, grey trunk. It produces small white flowers in summer and autumn and is a popular ornamental tree.
