Paperbark Thorn Overview

Pure stands of these beautifully shaped trees with their perfectly flattened crowns are quite stunning. Where else but in Africa would you encounter such a sight? Vachellia sieberiana var. woodii, commonly known as Paperback Thorn, is a magnificent, widely spreading, flat crown of deep green, feathery foliage and attractive creamy-tan to yellow-brown corky bark. The Paperback Thorn is suitable for planting in large gardens or parks, best planted individually to show off their magnificent shape, but will work well as a group of 3 to 5 trees planted in a grove. In nature, it is found growing in woodland, wooded grassland and along riverbanks. This tree is half-hardy and very fast-growing with fertile soil and sufficient water and tolerates temperatures ranging from about -2°C to 40°C. Plant in the sun. This tree was previously known as Acacia sieberiana, however these plants are now considered distinct. The genus name Vachellia refers to George Harvey Vachell (1789 – 1839), chaplain to the British East India Company in Macoa, who collected plants in China; sieberiana is named for Franz Sieber (1789-1844), a Bohemian botanist, traveller and plant collector.
