Acacia cultriformis, the Knife-leaf Wattle, is a bushy, medium to tall shrub.
The triangular-shaped phyllodes (hence the common name) are crowded along the branches. The size of the phyllode varies from 20 to 30 millimetres long by 6 to14 millimetres wide and bluish green in colour.
There is a prominent gland on the upper margin. Up to 30 flowers are carried in usually globular heads. The heads, on some plants, are almost oval in shape. Blooms are bright yellow and cover plants in mid spring. The pods, that follow the flowers, are linear and up to 70 millimetres long (see thumbnail).
Acacia cultriformis occurs on the western slopes of NSW extending into southern Queensland.
Acacia cultriformis appears to have several growth habits. In the Warrumbungle National Park, central NSW, plants are tall, upright shrubs. Planted specimens, near Tamworth, also central NSW, are rounded shrubs reaching a height of two metres. The specimens, in our cold climate garden, are tall shrubs with slightly pendulous branches.
The species name refers to the knife-like shape of the phyllodes.
