One of the world's rarest plants is to be unveiled at the Royal Botanic Garden (RBG) in Edinburgh.
Visitors to the glasshouses will be able to see a Malaysian rhodedendron, thought to be the only remaining example of the species in the world. The plant is one of several threatened species held in the RBG living plants collection, which curators hope will help inspire Scottish gardeners. The collection will also feature at the Gardening Scotland show in Ingliston. David Mitchell, the RBG's indoor curator, said the RBG's mission was to "explore and explain" the world of plants.
