Knife Acacia, Knife-Leaf Wattle, Dogtooth Wattle
Acacia cultriformis (Knife Acacia) is a small, multi-stemmed, evergreen tree of rounded to vase-shaped habit adorned with silvery-gray leaves shaped like paring knife blades. The foliage remains lovely all year round. In spring, masses of scented, fluffy, yellow flowers cover the branches and create a striking floral display. Relatively long-lived (50 years), Knife Acacia makes a dramatic focal point. It is useful as a barrier or screen and is also perfect for banks and slopes. Its cut branches are attractive in flower arrangements.
