This does not necessarily mean that you are restricted to plants endemic to your area – although many of these are obviously worthy candidates – but that plants from other areas will need to be able to cope with the prevailing climatic conditions.(Of course, all trees and plants should blend in with your overall garden theme and 
should not be invasive.)
South Africa’s regions tend to have their own distinctive style. For instance, in the Cape winelands, French, Dutch and even German influences have combined to create a memorable landscape which is often echoed in the formal gardens of this area. On a different scale, town living offers its own sense of place, varying from suburb to suburb and reflecting the lifestyle and aspirations of particular communities. To a large extent, a suburb’s trees, gardens and open spaces determine its appearance and can greatly enhance the quality of life for its inhabitants.
