Acacia davyi Seeds Common Names: Cork Thorn; Kurkdoring 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. Acacias have either bipinnate leaves or their leaves are replaced by flattened leave stalks, known as phyllodes, which perform the function of photosynthesis. 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, most notably, Acacia burkei, Acacia caffra, Acacia erioloba, Acacia karoo, Acacia nigrescens, Acacia robusta subsp. clavigera, Acacia robusta subsp. robusta and Acacia sieberiana var. woodii. The hard coated seeds remain viable for up to 30 years. They should be treated by heating and soaking for germination in spring. In cultivation many species are fast-growing but short-lived (10-15 years). They do best in full sun and well-drained soil. Some will take part-shade. Prune to shape after their flowers have fallen. Acacia davyi has a rather untidy appearance as a large tree, planted in open soil, but makes a very good subject for bonsai treatment. It has a very attractive corky bark and the new leaves are a beautiful fresh green. It is a hardy tree that is also fast growing. Out in nature it is usually found in hilly or mountainous areas with high rainfall but also does well in dryer areas. It has spines instead of thorns and the flowers are borne at the branch terminals and appear deep yellow to orange. You're buying a pack of 5 Seeds Growing Instructions will be sent to your email. |
