Eucalyptus leucoxylon, commonly known as the Yellow Gum, (South Australian) Blue Gum or White Ironbark, is a small to medium-sized tree with rough bark on the lower 1–2 metres of the trunk, above this, the bark becomes smooth with a white, yellow or bluish-grey surface. Adult leaves are stalked, lanceolate to broad-lanceolate, to 13 x 2.5 cm, concolorous, dull, green.
Flowers in white, pink or red appear during winter.
E. leucoxylon is widely distributed on plains and nearby mountain ranges or coastal South Australia, where it is known as the Blue Gum and extends into the western half of Victoria where it is known as the Yellow gum.
The species has been divided into numerous varieties and subspecies. A spectacular red-flowered form of uncertain provenance Eucalyptus leucoxylon ‘Rosea’ is widely planted as an ornamental plant, it flowers profusely in winter. A threatened subspecies known as the Bellarine Yellow Gum (Eucalyptus leucoxylon subsp. bellarinensis) is endemic to the Bellarine Peninsula at the south-eastern end of the species' range.
