Acacia aneura
Mulga Tree
The Acacia aneura, or Mulga Tree, is a hardy, slow-growing evergreen tree or shrub native to Australia, prized for its resilience in arid conditions and its ability to thrive in nutrient-poor soils. Reaching up to 10 metres, it features narrow, silvery-green phyllodes and produces golden-yellow, cylindrical flower spikes during winter and spring. Its dense canopy and adaptability make it a valuable addition to windbreaks, erosion control, and revegetation projects.
This iconic species is an essential part of arid Australian ecosystems, providing shade, shelter, and food for wildlife.
