Around the World in 80 Gardens

At Cape Town's famous Kirstenbosch Botanic Gardens Monty sees the King Proteus, South Africa's national plant, then in the Drakensberg Mountains he sees some native flora in its natural environment. His favourite garden is a school vegetable patch in Thembisa, one of Johannesburg's townships. Monty is intrigued by how gardening styles have changed here since the Dutch first settled in the 19th century.
