Cold- and drought-deciduous shrubs to 10 ft (3 m) high. The bark is smooth and gray. Stems are armed with paired, slender, white spines at the nodes. Leaves are bipinnate with 2--10 pairs of pinnae, each with 5--18 pairs of small, dark green leaflets. Showy yellow flower heads are produced in the summer months.


Native across a wide area of Africa from the Sahel through eastern Africa southward to South Africa. It is found in semiarid savanna and woodland habitats.

Sticky acacia is not available from nurseries. The flowers are attractive and contrast with the white spines and dark green foliage. Established plants are drought tolerant. This species appears to be hardy to 18° F (-7.7° C). Litter is minimal.
