Nestled in London's suburbs is the Kew Gardens, 320 acres of the most diverse, exciting and important plant life in the world. Cameras follow 12 months in the lives of its staff, beginning in winter. In the Palm House, Solene and her team are making sure the banana plants don't smash through the ceiling.

It's summer and Kew Gardens is enduring a drought, which means the staff have plenty of watering to do, along with the regular weeding and maintenance. Work continues in the Tropical Nursery too as Sam tends to the orchid collection and Lara busies herself pollinating plants.
