Vachellia karroo

Vachellia karroo


Shrub or small tree to 12 m. Bears straight spines or thorns (armed). Leaves are bipinnate. Bright yellow flowers in rounded heads from November to December. Pods are flat, curved and constricted between seeds.

The town of De Doorns (“the thorns”) is so named because of the prevalence of this species in the Hex River Valley.

V. karroo was previously known as Acacia karroo, but the name Acacia now only applies to the Australasian species.

Distribution in the Hex

Karroid scrub of De Doorns Renosterveld Karoo and De Doorns Arid Renosterveld.
