David Attenborough's Kingdom of Plants

The naturalist and film-maker explores the many varieties of plant life housed at the Royal Botanic Gardens in Kew, west London, and explains what they reveal about the natural world and the development of life on Earth. He begins inside the establishment's Palm House, whose climate has been engineered to simulate conditions found in rainforests, charting the evolution of plants that grow in the world's wettest regions and investigating how flowering plants spread across the globe so rapidly.
