Tropical rainforests are plant battlegrounds. New filming techniques allow us to enter the world of plants to see it from their perspective and on their timescale.

Water plants create beautiful, bizarre worlds. Flowers smother rivers and lakes. Plants fight and hunt. A river bubbles like champagne as plants create the atmosphere itself.

Plants of the seasonal world face constant change. They use use strategy, deception and feats of engineering to survive. Most importantly, they must get their timing right.

Desert plants spend decades in suspended animation waiting for rain, or they travel to find it. They survive using weapons, camouflage and surprising alliances with animals.

Two out of five wild plants are threatened with extinction. Today people are finding remarkable ways to help them, and so make our world a little greener and a little wilder.
