Galpinia transvaalica (Wild Pride of India)

Galpinia transvaalica is fast gaining popularity as a valuable and adaptable evergreen ornamental tree. Although this tree is naturally multi stemmed it can easily be turned into a single stemmed specimen with careful pruning. The highly decorative Wild Pride of India has an attractive rounded crown and produces an ever changing and colourful palette for much of the year as the older leaves turn bright crimson in spring before they fall, followed by the spectacular trusses of white flowers in summer and the clusters of bold red fruits in autumn. The lovely flowers attract hosts of insects which in turn attract a variety of insectivorous birds to the garden.

The Wild Pride of India is a beautiful addition to any garden but lends itself particularly well to the smaller or townhouse garden.

This fast growing, showy tree makes a lovely shade tree but can be very successfully pruned or trained into a hedge to form an attractive and colorful wind break, to create privacy or to screen unsightly walls or buildings or, as a beautiful evergreen backdrop to other plants.

Important Plant Families in South Africa - Mimosaceae


In order to facilitate the identification of our wealth of lovely South African trees, it is helpful to be familiar with the most prominent plant families in an area, as well as the characteristics that distinguish each plant family. Every month we will feature one of the most important and well represented plant families, focusing on easily recognisable features to assist identification.

Mimosaceae (Thorn tree family)

This very well represented plant family comprises about 100 tree species in southern Africa. Mimosaceae is one of three families belonging to the single Leguminosae family, the other two being Caesalpiniaceae and Fabaceae. These can easily be recognised by the fruit which consists of a seed bearing pod.

The most familiar representatives of this family are the Acacias and Albizias that are widespread throughout the bushveld regions of the country.

The family is distinguished by bipinnate leaves, sometimes feathery, and many have leaflets that fold up at night. Stipular scars are always present which, in the case of Acacias, are modified into thorns or spines. A distinctive feature is the thickening at each petiole and petiolule base while the fluffy, yellow or white flowers appear in the form of heads or spikes.

This family play an important part in nitrogen enrichment of soils as most members contain nitrogen fixing bacteria in the root nodules.

Various Acacias are of significant economic importance such as Acacia senegal, which produces gum arabic, an important component in the manufacture of various pharmaceuticals, cosmetics, foods, paints and adhesives. Products from Acacias are used in the tanning industry while the wood is also used for various commercial applications.

Members of the Mimosaceae family include; Albizia adianthifolia (Flat crown), Albizia tanganyicensis (Paperbark albizia), Acacia erioloba (Camel thorn), Acacia tortilis (Umbrella thorn), Acacia albida (Ana tree). 
 
Classification Euphorbia family

Top Facebook Query - March 2013


Gail Klein from California wrote:

My 12' tall Cunonia capensis has extreme chlorosis (not equal everywhere) and lots of suckering at the base. Just gave it iron sulfate. It gets lots of water and part sun. I'm hoping you can suggest a solution; they are very rare here in California so no local help is available. Thank you.

TreeCo responded:

The fact that the tree is sending out suckers, means that the tree is planted too deeply - and there is not enough air for the roots. This will also exacerbate chlorosis. These trees grow naturally over rocks in the kloofs and it is extremely vital that their root collar is above ground to prevent waterlogging. Although their roots cling over rocks in running water, they don't respond well to soil compaction and waterlogging. We would suggest loosening and removing some of the soil round the base of the tree / top of the roots and look at adding some vermicast (worm castings) around the base to promote microbial interactions.

Spectacular Monthly Tree - March 2013


The dense, dark green, drooping canopy of the magnificent Ficus natalensis makes it one of our finest indigenous shade trees. The size and growth habit of this handsome tree varies widely, depending on the climate and general growing conditions. In the Cape region for example, the Natal Fig has a neat single trunk and tends to be smaller than it’s counterparts growing in subtropical regions, where the canopy becomes far wider with a profusion of aerial roots and a buttressed trunk. The fruit or figs that are produced prolifically by these adaptable trees, while not suitable for human consumption, attract a great diversity of wildlife to the garden from birds to bats and a variety of insects. The versatile Ficus natalensis is wind and drought resistant and tolerates temperatures from -5C – 30+C.

Our Natal Figs are looking absolutely spectacular, so don't hesitate to place your order with us today.

Cordia caffra (Septee tree)

Cordia caffra is such a gorgeous tree that it should be planted far more extensively in cities and towns throughout the country. The beautiful, dense crown, decorative bark, masses of sweetly fragranced flowers and eye catching orange fruit ensure that the Septee tree looks lovely throughout the warmer months while in winter, the interesting patterns created by the bare branches, add a dramatic accent to the landscape. The decorative fruit, although edible, is not very tasty, birds however, find it quite irresistible while bees and insects are attracted to the fragrant flowers.
