Also called Knife Leaf Wattle, Dogtooth Wattle, Golden Glow Wattle, Half Moon Wattle, Knife Leaved Wattle
Knife acacia is a fast-growing evergreen wattle shrub or small tree native to eastern Australia, grown for its triangular leaf-like phyllodes and bright golden yellow flower balls. It is adaptable, drought tolerant and grows best in full sun to part shade.
Acacia cultriformis, known as knife-leaf wattle, dogtooth wattle, half-moon wattle or golden-glow wattle, is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia. It is widely cultivated, and has been found to have naturalised in Asia, Africa, North America, New Zealand and South America. A. cultriformis grows to a height of about 4 m (13 ft) and has triangle-shaped phyllodes. The yellow flowers appear from August to November in its natural range. Its attractive foliage and bright flowers make it a popular garden plant.
Its bright flowers and attractive leaves make Acacia cultriformis one of the most popular wattles in cultivation. Adaptable to the garden, it is grown in a wide range of soils and can tolerate frosts. It grows in sun or part shade. Drought tolerant, it can be used to combat soil erosion. Acacia 'Cascade' (RN: ACC154) is a prostrate form that spreads to a diameter of 2 m (7 ft). It was registered on 18 November 1982, having been propagated by Bill Molyneux at his nursery in Montrose, Victoria from a selected seedling. It makes an attractive cascading plant in a rockery.
A. cultriformis is used as cut flowers.
Acacia cultriformis is found on the western slopes of the Great Dividing Range in central New South Wales and southern Queensland. It occurs discontinuously north from Wagga Wagga and Narrandera to west of the Denman - Singleton area, and to Stanthorpe and Inglewood in south-eastern Queensland. It grows in clay-loam or sandstone soils in Eucalyptus woodland, often on rocky ridges.
