Salvadora and the Strange Oasis

Salvadora persica, which goes by many common names such as miswak and arak in Arabia, or the mustard bush or toothbrush tree because its twigs can be used as a natural toothbrush.

Battling invasive cacti

In order to save water, and because they have beautiful flowers and are often easily available, one may be tempted to plant cacti in the garden. However, the entire African continent boasts no indigenous cactus species. All cacti originate from the tropical and subtropical regions of the Americas. Being very well adapted to arid conditions, they thrive excellently in our dry climate and since they are from a different part of the world they experience a total lack of indigenous pests or diseases in Namibia.
