Acacia cultriformis, commonly known as Knife-Leaf Wattle, is an evergreen shrub native to the open woodlands and dry scrublands of Australia, specifically in New South Wales and Queensland. It can grow to a height of about 4 meters (13 feet) and has distinctive triangular, silver-gray phyllodes that resemble knife blades. The bright yellow, rod-shaped flowers bloom from August to November in its natural range, creating a striking contrast against the foliage. Knife-Leaf Wattle is known for its showy floral display and unique foliage texture.

Knife-Leaf Wattle is valued for its ornamental qualities, including its attractive foliage and bright flowers, making it a popular choice for gardens. It is also used for soil stabilization and erosion control due to its adaptability to a wide range of soils and its drought tolerance. In cultivation, it thrives in full sun to part shade and prefers soils with fast drainage. While it is drought-tolerant once established, it benefits from occasional watering during prolonged dry periods. ’Acacia Cascade’ is a popular garden cultivar with a prostrate habit, spreading up to 2 meters (7 feet) in diameter, ideal for rockeries and as ground cover. However, gardeners should be aware that Acacia cultriformis can become invasive outside its native range and should be monitored to prevent unwanted spread.CC BY-SA 4.0
