Umbrella Thorn Acacia (Acacia tortilis) also known as Umbrella Thorn and Israeli Babool, is a medium to large canopied tree native primarily to the savanna and Sahel of Africa (especially Sudan), but also occurring in the Middle East.

In extremely arid conditions, it may occur as a small, wiry bush. It grows up to 21 m ft in height. The love carries leaves that grow to approx. 2.5 cm in 0 in length with between 4 and 10 pair of pinnae each with up to 15 pairs of leaflets. Flowers are small and white, highly aromatic, and occur in tight clusters. Seeds are produced in pods which are flat and coiled into a springlike structure.

The plant is known to tolerate high alkalinity, drought, high temperatures, sandy & stony soils, strongly sloped rooting surfaces, and sand blasting. Also, plants older than 2 years have been observed to be somewhat frost resistant.
