Notes
Knife acacia (Acacia cultriformis) is a tree for borders, hedges, and low maintenance gardens. It grows outdoors year-round in USDA zone 9 and warmer, down to about 20°F (-7°C). In colder areas, grow it as a houseplant or bring it indoors for winter. This plant likes full or part sun and dry to moist, sandy, loamy, or clay soil. Deer rarely make it their first choice. The evergreen leaves are fragrant, and the tree is drought tolerant. Birds visit it.
Pairs well with Camphor tree, Bougainvillea, Sedge, and Seagrape.
