Characteristics:
Eucalyptus leucoxylon is a medium sized, evergreen, woodland tree with an upright and narrow form. The white ironbark's leaves are linear, two and a half inches long, and one eighth of an inch wide. Its trunk is smooth and white, which is starkly contrasted against its blue-gray leaves. E. leucoxylon has yellow flower buds, which bloom into protandrous flowers in the fall, eventually fading into brown capsules (1, 2). The flowers are a variety of colors, from cream, to pink, to red. E. leucoxylon 'Rosea' is quick to establish, and produces abundant, scarlet to fuschia colored flower clusters.

Natural History:
Eucalyptus leucoxylon is native to Australia, and like many Australian native plants it is valued around the world as a landscape ornamental. In the mid-late 1800s many eucalyptus species were brought to the United States for an assortment of purposes. Some species were introduced as landscape ornamentals, and as windbreaks, while others were tested as sources of fiber and lumber. E. leucoxylon however, was primarily introduced for ornamental purposes, and to improve honey production, given its attractiveness to bees (3).
Cultivation Notes:
Primarily found in southern Australia, E. leucoxylon is well adapted for arid regions, and is widely tolerant of adverse conditions, including heat, wind, drought, and heavy or rocky soils. This tree grows best in full sun. The white ironbark requires very little water, and overwatering should be avoided. It should be watered approximately once a month, or once every other month, though occasional supplemental water might aid growth, especially during dry years (4). E. leucoxylon can be trained, and should be pruned to keep the tree narrow and upright, and reduce long overhanging branches, which tend to break in high winds. For those choosing a specimen, it is best to select a plant that is in bloom to find the right flower color, as there are many varieties. E. leucoxylon is susceptible to chlorosis, in order to prevent this, iron chelate can be applied in its early growth stages. This tree is hardy to 15°F.
Ethnobotany:
The oils from Eucalyptus leucoxylon leaves have been used to flavor different foods and candies in Australia. Other countries have used this tree for its tendency to attract bees and improve honey production (1, 4). The white ironbark is primarily used in residential areas, as well as narrow commercial spaces (1). In landscapes, this tree can be clustered and used as a screen due to its single or multi-trunked form.
