Blue gum is one of the most extensively planted eucalypts. Its rapid growth and adaptability to a range of conditions is responsible for its popularity. It is especially well-suited to countries with a Mediterranean-type climate, but also grows well in high altitudes in the tropics.
Blue gums have historically been used as street trees but are now regarded as unsuitable by many municipalities due to their rapid growth and mature size.
Timber and fuelwood
Blue gum timber is yellow-brown, fairly heavy, with an interlocked grain, and is difficult to season. It comprises 65% of all plantation hardwood in Australia with approximately 4,500 km² planted. The tree is widely cultivated elsewhere in the world. It is primarily planted as a pulpwood, and also as an important fuelwood in many countries. It has poor lumber qualities due to growth stress problems, but can be used in construction, fence posts and poles.
Essential oil
The leaves are steam distilled to extract eucalyptus oil. E.globulus is the primary source of global eucalyptus oil production, with China being the largest commercial producer. The oil has therapeutic, perfumery, flavoring, antimicrobial and biopesticide properties. Oil yield ranges from 1.0-2.4% (fresh weight), with cineole being the major isolate. E.globulus oil has established itself internationally because it is virtually phellandrene free, a necessary characteristic for internal pharmaceutical use. In 1870, Cloez, identified and ascribed the name "eucalyptol" — now more often called cineole — to the dominant portion of E. globulus oil.
Herb tea
Blue gum leaves are used as a therapeutic herbal tea.
Honey
Blue gum flowers are considered a good source of nectar and pollen for bees.
