John Anderson, Keeper of the Gardens, Windsor Great Park, UK

John Anderson began his garden training at the National Botanic Gardens at Glasnevin, Dublin and went on to study at the Royal Botanic Gardens, Kew. His first appointment as Head Gardener was at the famous Mt. Usher Gardens in Co. Wicklow, where he was also curator of the National Collection of Eucryphia, Eucalyptus and Nothofagus. Subsequently he undertook an appointment with the National Trust for Scotland in Inverewe, and then in 2006 moved to Exbury in southern England, home of the Rothschilds, located among 200 acres of woodland gardens along the coast of Hampshire. At each of these later gardens he was responsible for curating National Collections of various species of interest in our area.

John remained at Exbury for ten years before moving on to an even more prestigious appointment in 2016.  As the fourth Keeper of the Gardens at Windsor Great Park, he is responsible for the Savill Garden, Valley Gardens, and Her Majesty’s Private Garden at Frogmore.

In addition to his work at Windsor Great Park, John is also Vice-Chairman of the RHS Plant Committee and an RHS Judge.
