SA Tree No:
It is a most classically shaped Acacia and is the well known emblem of one of our commercial banks and was the subject of many of Pierneef's paintings. The flat top droops slightly at the edge, producing an umbrella shape. It occurs naturally in South Africa, Namibia, Botswana and Zimbabwe. Noah apparently used this wood to make The Arc. It has both hooked and straight thorns.The flowers open in summer and are white pompoms and sometimes so profuse that the tree appears blanketed in snow. Baboon and monkeys enjoy eating the flowers. It makes a striking specimen and is highly sought after for bonsai. It requires full sun and survives drought and frost. It grows well in any soil even in clay soil although it is an indicator in the wild of good soil and grasses for grazing. It stabilizes the soil. The bark is used to make fibre for ceremonial skirts and it is used to make a yellow dye. Elephant are fond of the bark and often tear off strips which result in the death of the tree. In the Kruger National Park sharp rocks are placed around the trees to protect them from the elephants as they don't like walking on sharp rocks. Attracts birds and butterflies. The leaves are browsed by elephant, giraffe, eland, waterbuck, kudu, gemsbok, nyala, springbok, bushbuck, impala, duiker and giraffe while the contorted pods are enjoyed by monkeys, baboons and parrots. The gum is edible and is enjoyed by Bushbabies. It is slow growing but the wood is used for fuel. It is planted to stabilize the soil as it has an extensive root system. It is the larval host plant for the Topaz Blue and the Brown Playboy. Named for Rev George Harvey Vachel (1798-1839) a British priest and plant collector. He was chaplain to the British East India company in China where he collected plants.
