The naturalist concludes his exploration of the Royal Botanic Gardens in Kew, west London, by examining plants that have evolved to minimise their dependence on water, enabling them to survive in the world's driest environments. He witnesses a cactus blooming at midnight, tells the story of the spectacular flowering of the Agave franzosinii, and visits the Millennium Seed Bank, a facility designed to save plants from future extinction.
