RHS Garden Wisley is thus the society's oldest garden. Rosemoor came next, presented by Lady Anne Berry in 1988. Hyde Hall was given to the RHS in 1993 by its owners Dick and Helen Robinson. Dick Robinson was also the owner of the Harry Smith Collection which was based at Hyde Hall. The most recent addition is Harlow Carr, acquired by the merger of the Northern Horticultural Society with the RHS in 2001. It had been the Northern Horticultural Society's trial ground and display garden since they bought it in 1949. In 2013, more than 1.63 million people visited the four gardens.
