“Durban Botanic Gardens is Durban’s oldest public institution and Africa’s oldest surviving botanical gardens.
The Durban Botanic Gardens was established to participate in the quest of Kew Gardens to establish a series of botanic gardens across the world which would assist in the introduction of economically valuable plants, and to supply plants to Kew that were new to science.” (1)
