The South China National Botanical Garden was established by relying on the South China Botanical Garden of the Chinese Academy of Sciences. South China National Botanical Garden is committed to plant conservation, scientific research and knowledge dissemination in the tropical and subtropical regions of the world. Its predecessor is the Institute of agroforestry and botany of National Sun Yat sen University. It was founded by the famous botanist Chen Huanyong in 1929.

The planning and construction of the South China National Botanical Garden takes the ex situ conservation of plant resources in South China as the core, taking into account the global tropical and subtropical regions, and builds the national ex situ conservation center of rare and endangered plants and germplasm resource bank, so as to improve the ability and efficiency of ex situ conservation of plants, and realize the conservation of more than 20000 species, including about 6000 economic plants, and 95% of the rare and endangered plants in South China have been ex situ conserved.
