Acacia saligna (Acacia cyanophylla)Coojong

The Acacia saligna, or Coojong, is a fast-growing, hardy evergreen shrub or small tree native to Australia, known for its adaptability and resilience in a wide range of environments. Reaching up to 7 metres, it features long, arching blue-green phyllodes and bright golden-yellow flower clusters in late winter to spring. Its spreading growth habit and ability to thrive in poor soils make it a valuable choice for erosion control, windbreaks, and revegetation projects.

This versatile and low-maintenance plant is also popular in ornamental landscaping, particularly in arid and coastal areas.
