Spectacular Monthly Tree - February 2010

The beautiful Rauvolfia caffra with it’s glossy, dark green leaves, wide crown and slightly drooping branches is an ideal specimen tree and looks best when planted on a large lawn or wherever the lovely shape can be appreciated. The inconspicuous small white flowers are borne in sprays and are sweetly scented while the round, fleshy fruit is green with white spots becoming black and wrinkled when mature. The pale brown, soft wood is used in general carpentry as well as for kitchen utensils and carved drums. The latex and especially the bark and roots of the Quinine tree are well known for their use in traditional medicine. This attractive, fast growing tree should definitely be planted more extensively in South Africa.

Our stock specimens of 200kg Rauvolfia caffra are looking absolutely incredible and are a really good deal for their bag size. They are tall and sturdy with exceptionally strong trunks so they will more than likely not need staking once planted.

Kigelia africana

Every visitor to the Kruger park has seen the spectacular Kigelia africana. Although it is native to the warmer regions of the country, it can be seen growing beautifully in many other areas throughout South Africa. The Sausage tree tolerates a wide variety of conditions but is not frost hardy. This beautiful shade tree is evergreen but in areas where there are long dry periods, some loss of leaves may occur. The large, deep red flowers appear in early spring and literally overflow with nectar, attracting a variety of birds, insects and the nectar eating fruit bats, that pollinate the tree. The long, sausage shaped fruits may take up to 6 months to mature, giving the tree it’s distinctive appearance. In the wild, Kigelia africana attracts a variety of game that feed on the flowers and the fruit.

Olea europaea subsp. africana – Wild olive


The Olea africana is a small, neat evergreen tree with a dense spreading crown of shiny grey-green to dark green foliage that is silvery underneath. This has to be one of our most versatile trees as it tolerates a wide variety of growing conditions as can be seen by the extensive distribution throughout the country. At this time of the year, when water is at a premium, and strong winds and searing heat create extremely difficult growing conditions for many plants, the Wild Olive comes into it’s own, as it is able to withstand the harshest conditions. As an added bonus, the sprays of whitish flowers are lightly scented and the fruits attract an interesting assortment of fruit eating birds to the garden.
