The Acacia tortilis, commonly known as the Umbrella Thorn Tree, is an iconic, hardy deciduous tree native to arid regions of Africa and the Middle East. It is recognized for its distinctive flat-topped canopy, feathery, bipinnate leaves, and long, sharp thorns. Growing up to 10–12 meters tall, it is a key species in savannah ecosystems, providing shade, forage, and shelter for wildlife.
With its extreme drought tolerance and adaptability, the Umbrella Thorn Tree is an excellent choice for arid landscaping, erosion control, and ecological restoration projects.
