David Attenborough takes us on a guided tour through the secret world of plants, to see things no unaided eye could witness. Each episode in this six-part series focuses on one of the critical stages through which every plant must pass if it is to survive:- travelling, growing, and flowering; struggling with one another; creating alliances with other organisms both plant and animal; and evolving complex ways of surviving in the earth's most ferociously hostile environments.

This is the story of a vegetable garden, from the first seeds to the harvest. But this garden is different, because here the gardener has decided to banish pesticides and other chemicals, and to be helped only by discreet workers, the insects. As we dive into the heart of this plant kingdom, we discover thousands of tiny lives that organize themselves as in a micro-society: decomposing insects, recyclers, pollinators, the workers of the garden work to maintain a fragile balance within the vegetable garden. As the plants grow and begin to produce their first vegetables, the incredible interactions between insects and plants help protect the future harvest. But it is also their personal stories that punctuate the life of the garden. Between parades, mutual aid and attempted putsch, the story of the vegetable garden thus takes the form of a true nature tale.
