As the first botanic garden in the UK (founded in 1621), at the UK’s oldest University, Oxford Botanic Garden occupies a world-class position in terms of its history and academic location. Harcourt Arboretum (acquired by the University in 1947), a 15 minute drive from Oxford, contains some of the finest conifer collections in the UK set within 130 acres of historic Picturesque landscape. Together, the Garden and Arboretum are an incredible resource for research, education, conservation and inspiration for a new generation of botanists.
