Also known as Acacia Giraffe, this small tree is native to South Africa.  It should be planted in full sun.  As it is slow growing, it will eventually become a large shrub or small tree perhaps to 20 feet by 35 feet across.  Noting the size, you might surmise the tree forms a flat-topped canopy that is often depicted in images of South African deserts. The wide spreading branches cast considerable shade in the hot desert. The slow growth creates very hard wood prized as a source of fuel in the native land. The prominent thorns are formed in pairs and as a result, the placement of this tree requires some consideration.
