The Royal Botanic Garden Edinburgh was founded in the 17th century as a ‘Physic Garden', growing medicinal plants. This first Garden was in St Anne's Yard, part of the Holyrood Palace grounds, and occupied an area the size of a tennis court. It now extends to four sites - Edinburgh, Benmore (near Dunoon in Argyll), Logan (near Stranraer in Galloway), and Dawyck (near Peebles in the Borders), and is the second richest collection of plant species in the world.
