Over 20,000 plant species sprout from South Africa's soil - an amazing 10% of the world's total, although the country constitutes only 1% of the earth's land surface.
Dozens of flowers that are domesticated elsewhere grow wild here, including gladiolus, proteas, birds of paradise and African lilies. South Africa is also the only country with one of the world's six floral kingdoms within its borders.
In the drier northwest, there are succulents (dominated by euphorbias and aloes), and annuals, which flower brilliantly after the spring rains, and are one of Northern Cape's major tourist attractions.
In contrast to this floral wealth, South Africa has few natural forests. They were never extensive, and today only remnants remain. Temperate forests occur on the southern coastal strip between George and Humansdorp, in the KwaZulu-Natal Drakensberg and in Mpumalanga. Subtropical forests are found northeast of Port Elizabeth in the areas just inland from the Wild Coast, and in KwaZulu-Natal.
In the north are large areas of savanna, dotted with acacias and thorn trees.
