About

Eucalyptus globulus, commonly known as southern blue gum, is a species of flowering plant in the family Myrtaceae. It is a tall, evergreen tree endemic to southeastern Australia. This Eucalyptus species has mostly smooth bark, juvenile leaves that are whitish and waxy on the lower surface, glossy green, lance-shaped adult leaves, glaucous, ribbed flower buds arranged singly or in groups of three or seven in leaf axils, white flowers and woody fruit.

There are four subspecies, each with a different distribution across Australia, occurring in New South Wales, Victoria and Tasmania. The subspecies are the Victorian blue gum, Tasmanian blue gum, Maiden's gum, and Victorian eurabbie.

Where it grows

Blue gum grows in forests in New South Wales, Victoria and Tasmania, including some of the Bass Strait Islands. The nominate subspecies E. g. subsp. globulus is mainly found in lowland parts of Tasmania, but is also found on some Bass Strait islands including King Island, and in the extreme south-west of Victoria. Subspecies E. g. subsp. bicostata occurs in montane and tableland areas between the Carrai Plateau in northern New South Wales and the Pyrenees in Victoria. Subspecies E. g. subsp. maidenii occurs on near-coastal ranges of south-eastern New South Wales and eastern Victoria. Subspecies E. g. subsp. pseudoglobulus is mostly distributed in eastern Gippsland but there are isolated populations further inland and in the Nadgee Nature Reserve in south-eastern New South Wales.
