Landscape Use
Sweet acacia can be grown in the home landscape in dry soils in full sun. If the area is moist it must be well drained so as not cause root rot. It is very drought tolerant and once established and requires little, if any, maintenance. It is salt tolerant, and can tolerate temperatures down to 20 degrees.
Placement needs to be carefully considered because of the thorns, and the fact that acacia can become clonal and form a dense thicket.
It grows in zones 9 to 11.
Wildlife Uses
The fragrant flowers attract a number of pollinators, but mostly bees and wasps.
The butterflies that visit are generally the smaller species such as hairstreaks and skippers.
Songbirds forage among the branches for insects.
Deer eat the seed pods, and game birds such as quail and doves eat the seeds once the pods open and fall to the ground.
Propagation
Can be grown easily from seed and transplanted when small. Some may have luck with rooting cuttings.
