These ten episodes unfold the story of the year, from the buds of spring to the sweltering days of summer. We see the arrival of wallabies at Kew, the planting of a new Mediterranean garden and the first steps in trying to reconstruct a botanical garden in Montserrat that was destroyed by a volcano. Viewers will be able to follow an intrepid Kew scientist as she searches China for medicinal plants; watch a Kew scientist working with farmers in Ghana controlling pests on vital food crops; see how Kew charts early and un-seasonal flowering; and witness the efforts of Kew scientists to encourage poor South Africans to grow plants that are believed to be effective treating HIV. Share the anxieties of Hugh, a scientist in the world-famous Millennium Seed Bank, trying to propagate some 200-year-old seeds discovered by accident in the National Archives. Join in Sarah's excitement as she prepares for a Royal opening. The series enters the lives of the people who care for Kew, demonstrating how important plants are for visitors, medicine and conservation around the world.
