Common Names: Silky Thorn; Sydoring Acacia is a large genus, in the Fabaceae family, that contains over 1200 species of trees and shrubs from warm climates. Some are deciduous but most are evergreen. Over 700 species are native to Australia. There are 40 species, subspecies and varieties of Acacia indigenous to South Africa. They range from low-growing shrubs to tall trees and many have been introduced to other countries for economic and ornamental purposes. Acacias are also common in tropical and subtropical Africa; most African species are characterized by vicious spines and referred to as ‘thorn trees’. The name Acacia is derived from "akis" meaning a point or barb. The flowers, ranging from deep golden yellow to cream or white, and crowded into globular heads or cylindrical spikes, are often fragrant and produce abundant, bee-attracting pollen. The fruit of Acacias are either round or flattened pods. They do well in most parts of South Africa, and resist all but the severest frosts. Many of them make suitable bonsai candidates. The hard coated seeds remain viable for up to 30 years. They should be treated by heating and soaking for germination in spring. They do best in full sun and well-drained soil. Some of the more popular African Acacia species include Acacia arenaria, Acacia ataxacantha, Acacia borleae, Acacia brevispica, Acacia burkei, Acacia caffra, Acacia davyi, Acacia erioloba, Acacia erioloba x haematoxylon, Acacia exuvialis, Acacia fleckii, Acacia galpinii, Acacia gerrardii, Acacia grandicornuta, Acacia haematoxylon, Acacia hebeclada, Acacia hebeclada ssp. chobiensis, Acacia hebeclada ssp. hebeclada, Acacia hebeclada ssp. tristis, Acacia karroo, Acacia luderitzii var. luderitzii, Acacia luederitzii, Acacia mellifera, Acacia montis-usti, Acacia natalitia, Acacia nigrescens, Acacia nilotica, Acacia permixta, Acacia polycantha, Acacia polycantha ssp. campylacantha, Acacia reficiens, Acacia rehmanniana, Acacia robusta, Acacia schweinfurthii, Acacia senegal, Acacia sieberiana var. woodii, Acacia swazica, Acacia tortilis and Acacia xanthophloea. Acacia rehmanniana is a distinctive small to medium sized tree to 12 m tall, with a spreading crown. It has conspicuously reddish brown bark on young trees becoming darker with age, and dense golden yellow hairs on the youngest branches. It usually occurs solitary in wooded grassland and bushveld on a range of soils, often clay rich such as in vlei margins. It is a southern African species, quite resistant to frost. It can be found in miombo and similar woodlands as well as Acacia woodland with Acacia karroo. You're buying a pack of 10 Seeds Growing Instructions will be sent to your email. |
