Timothy Walker

Timothy is a Botanist, Horticulturist and Gardener. He is an Author, and also a lecturer at Somerville College, Oxford. After training at a number of gardens including Windsor Great Park and the Royal Botanic Gardens, Kew, Timothy commenced work at Oxford Botanic Gardens in 1986. Appointed as "Horti Praefectus" (Superintendent/Director) there in 1988, he held that position until 2014. Under Timothy's watch, the garden won four gold medals at the Chelsea Flower Show, and developed 67 acres of MG5 wild flower meadow at the Harcourt Arboretum; a UK threatened habitat. Timothy remains an active practical gardener as well as a highly respected international academic in the fields of horticulture and plant botany.
