Blackbursh acacia, like other species of this genus, is not used for direct human consumption although it does have some indirect forms of consumption. For example, Native Americans have used the blackbrush acacia as an ingredient in medications (4). Tea can be made from the flowers, which exhibits sedative properties. The roots of the plant also serve as a source for tea, which can be used to treat sore throats, coughing, and mouth inflammations (2). Other uses for A. rigidula include the use of its seeds to alleviate stomachaches and treat diarrhea. The leaves can also be ground into a powder to stop bleeding, relieve chafed skin and can even be used as an antimicrobial wash (4). Phytochemical stimulants found in the plant, including some amphetamines, are found in dietary supplements and weight loss medications (5). This plant also forms a small part of the diet of some wild animals. It is not the preferred source of food for deer and other animals, but it can be consumed when other food resources are scarce (1). Its flowers also provide nectar for bees and butterflies (3).
For landscape purposes, A. rigidula works well as a physical barrier or screen but is also outstanding when displayed by itself. This plant is best suited for transition and arid zones when using xeriscape techniques. The dark, green foliage of A. rigidula makes for a great backdrop for light-colored plants, and with proper training, this shrub is able to take the form of a small tree (6).
