Eucalyptus globulus, the Tasmanian bluegum, southern blue-gum or blue gum, is an
evergreen tree, one of the most widely cultivated trees native to Australia. They
typically grow from 30–55 m (98–180 ft) tall. The tallest currently known specimen in
Tasmania is 90.7 m (298 ft) tall. There are historical claims of even taller trees, the
tallest being 101 m (331 ft). The natural distribution of the species includes Tasmania
and southern Victoria (particularly the Otway Ranges and southern Gippsland). There are
also isolated occurrences on King Island and Flinders Island in Bass Strait and on the
summit of the You Yangs near Geelong. There are naturalised non-native occurrences in
Spain and Portugal, and other parts of southern Europe incl. Cyprus, southern Africa,
New Zealand, western United States (California), Hawaii, Macaronesia, and the Caucasus
(Western Georgia). The d'Entrecasteaux expedition made immediate use of the species when
they discovered it, the timber being used to improve their oared boats. The Tasmanian
blue gum was proclaimed as the floral emblem of Tasmania on 27 November 1962. The
species name is from the Latin globulus, a little button, referring to the shape of the
operculum.
