Looking for a versatile tree that has many uses? Look no further than the Eucalyptus globulus, also known as Blue Gum and Tasmanian Bluegum. This evergreen tree is native to Australia but has become widely cultivated and naturalized in other parts of the world, including California. Its smooth, bluish-white bark peels in large strips, and its broad juvenile leaves are covered in a blue-grey, waxy bloom, giving it its common name. The mature leaves are a shiny dark green and narrow and sickle-shaped in appearance. The cream-colored flowers produce nectar that yields a strongly flavored honey. This tree is widely grown for its essential oil, which has powerful antiseptic properties and is used to relieve coughs, colds, sore throats, and other infections. The Eucalyptus globulus is also used for timber, pulpwood, and as an herbal tea. However, the tree has become a noxious weed in California, where it is considered invasive due to its ability to displace native plant communities and its high fire hazard. Despite this, the Blue Gum remains the most widely cultivated of all Eucalyptus trees, appreciated by many for its many uses.
