The Royal Botanic Gardens in Kew in south-west London are the home of the largest collection of plant species in the world. The gardens, which have been listed as a UNESCO World Heritage Site since 2003, are the oldest of their kind. They were created nearly 250 years ago from a number of smaller gardens, all of which were in the possession of the royal family. In the course of time, the different areas grew together to form a single large park designed by various landscape architects. The gardens flourished under King George III, who was known by the people as “Farmer George”. In the early 19th century, he had plants collected from all over of the world and brought here.
