About

Eucalyptus leucoxylon, commonly known as yellow gum, blue gum or white ironbark, is a species of small to medium-sized tree that is endemic to south-eastern continental Australia. It has smooth yellowish bark with some rough bark near the base, lance-shaped or curved adult leaves, flower buds in groups of three and cylindrical, barrel-shaped or shortened spherical fruit. A widely cultivated species, it has white, red or pink flowers.

Where it grows

This eucalypt species is found in Victoria, south-eastern South Australia and far south-western New South Wales. All six subspecies occur in Victoria. Subspecies bellarinensis is only known from the Bellarine Peninsula near Ocean Grove and Torquay. Subspecies connata grows on skeletal soils, mostly in the Brisbane Ranges. Subspecies leucoxylon is the most widespread species and occurs in scattered populations across Victoria and in south-eastern South Australia, including on Kangaroo Island where the tallest specimens are found. Subspecies megalocarpa is a stunted tree or mallee only found in coastal areas from the far south-east of South Australia to far western Victoria. Subspecies pruinosa occurs in drier areas of South Australia, the Wimmera and Goldfields of Victoria and on the Murray River floodplain near Barham in New South Wales.
