Common Name
Oil Mallee
Description
Eucalyptus oleosa ‘Oil Mallee’ is a hardy, small to medium-sized mallee eucalypt with a dense, multi-stemmed habit arising from a lignotuber. The narrow, blue-green leaves are rich in aromatic oils and provide a soft, elegant texture in the garden. Clusters of small white to cream flowers appear in spring and summer, attracting nectar-feeding birds and native bees. Its multi-stemmed, bushy habit makes it ideal for screening, windbreaks, or feature planting, while the aromatic foliage adds practical and sensory value.

Habitat
Eucalyptus oleosa occurs naturally across semi-arid regions of southern and inland Australia, typically on well-drained sandy or loamy soils. In the garden, it thrives in full sun and well-drained soil, is extremely drought tolerant once established, and handles light frost. Minimal pruning is needed beyond early shaping. Its resilience and low water requirements make it perfect for windbreaks, essential oil use, or planting in challenging, dry conditions.
Cultural SIgnificance
Traditionally valued by Aboriginal peoples for its medicinal properties and aromatic oils, with various parts of the plant being used for traditional remedies and the species being an important component of arid landscape ecosystems.
