Karoo Desert is the only true succulent garden in the Southern Hemisphere. Set in magnificent surroundings at the foot of the Hex River Mountain range near Worcester, it concentrates on plants from the arid or semi-desert parts of the country. The garden has fine specimens of tree aloes, euphorbias, wild grapes and a great variety of smaller species. Chief among these are the mesembs, or 'vygies' which, together with the annual daisies, provide a dazzling kaleidoscope of colour in spring (August-mid October). The garden was orignally at Whitehall and was moved to Worcester in 1946.
