Karoo Desert National Botanical Garden Karoo Desert National Botanical Garden The Karoo Desert National Botanical Garden is a botanical garden focused on succulents and other plants of arid regions, that lies at the foot of the Hex River Mountains range, in the town of Worcester, South Africa. It was originally set up in 1921 near Matjiesfontein further inland. However, in 1945 it was moved to Worcester. It is today one of nine National Botanical Gardens that are run by the South African National Biodiversity Institute (SANBI). The Garden spans an area of with only being cultivated. The remainder preserves the natural vegetation of the area,

An exception is the thriving ostrich-farming industry in the Little Karoo, which is heavily dependent on supplementary feeding with lucerne. The difference between the Succulent Karoo biome and the Nama Karoo biome is that the former receives the little rain that falls as cyclonic rainfall in winter, which has less erosive power than the infrequent but violent summer thunderstorms of the Nama Karoo. Frost is also less common in the Succulent Karoo biome than in the Nama
