More about Charles

Charles started his career at the Botanical Research Institute in Pretoria in 1972 until 1982, during which time he spent three years as the South African Liaison Botanist in London at the Royal Botanical Gardens at Kew. He returned briefly to South Africa for two years but then went back to London to assume a new post at Kew Gardens, serving as the Krukoff Botanist for Neotropical Legume Research. After a two-year stint he returned to his alma mater at the University of Natal as Associate Professor at the Department of Botany, but once again headed to Kew Gardens as research co-ordinator in NE Brazil, and later as Deputy Director and Director of Science and Horticulture at Kew until 1996.

He worked under the principle that ‘Gardens are great places to grow people’. He says, “My approach was to implement a cradle-to-cradle approach where a parent would bring their child to the garden and they in turn would bring their own child. The time it takes for cultural change to take place”.
