Acacia mellifera (Senegalia)Black Thorn Tree

The Acacia mellifera, commonly known as the Black Thorn Tree, is a hardy, deciduous shrub or small tree native to arid and semi-arid regions of Africa. It is recognised for its dense, thorny branches, small feathery leaves, and fragrant creamy-white flowers that bloom in clusters during the wet season. Growing up to 5 to 7 metres, it is an excellent choice for windbreaks, erosion control, and wildlife habitat in harsh climates.

Adapted to extreme conditions, the Black Thorn Tree provides forage for livestock, nectar for bees, and serves as an essential component of ecological restoration projects.
