The South West Nature Reserve, better known as the National Botanical Garden, is located in the heart of Windhoek. The area was originally earmarked as a nature park, but lack of funding resulted in this project not materialising. In 1990, the National Botanical Research Institute (NBRI) moved into the buildings adjacent to the reserve and developed the area as a botanical garden funded  by the Ministry of Agriculture, Water and Forestry, to which the NBRI belongs.

The garden is aimed at protecting and promoting the sustainable use of Namibian flora, with an emphasis on education and recreation. Most of the garden has not been landscaped. This is to conserve water and present plants in their natural environment, allowing visitors to learn about indigenous vegetation and water-wise gardening.

The Desert House, where fascinating plants from the Namib Desert are displayed, was added in 2007. Other features include a dense stand of the Windhoek aloe (Aloe littoralis), the symbol of the city of Windhoek and the Lily Walk, which attracts visitors when the plants are in bloom during April.
