In November 1999 and in February 2001 I visited South Africa twice at the invitation of Mr. and Mrs. N. Oppenheimer, in order to give them advise on the use of indigeneous plants in their garden (Brenthurst Gardens) in Johannesburg. In order to find inspiration I visited the following nature areas: Telperion (at the border of Gauteng and Mpumalanga), Pilanesberg and Magaliesberg in the North West Province and Tswalu (Northern Cape, between Hotazel and Vanzylsrus, bordering the Kalahari Desert).
