The Green Planet

Between the tropics and the frozen poles lies a region dominated by relentless change in the form of the four seasons: spring, summer, autumn and winter. Each one presents plants with huge challenges, from ice and snow to raging fires, from intense competition to surprising enemies. This is a world of astonishing variety and vibrant colour. To survive here plants must use strategy, deception and remarkable feats of engineering. Most importantly, they must get their timing right.
