Picture Shows: The Aspen (Populus tremuloides) forests of Colorado flush a brilliant yellow in the Autumn, as the trees start to shutdown and prepare to lose their leaves in order to survive the winter.

The Green Planet’s deep dive into the surprising and secret world of plants has taken us to the tropics and under the water’s surface – next we’ll discover what happens to plants in regions subjected to relentless changes from the four seasons.

Watch The Green Planet on WITF TV Wednesday, July 20 at 8pm or stream it for free for four weeks after its broadcast premiere through the PBS Video app.

Each season presents plants with enormous challenges – from ice and show to raging fires, from intense competition to surprising enemies from both animals and plants.

Plants survive in this world of astonishing variety and vibrant color by using strategy, deception and incredible feats of engineering. Most importantly, they must get their timing right.

The Green Planet uses pioneering motion-control robotic systems, thermal cameras, macro frame-stacking and ultra-high-speed cameras to give viewers a glimpse of plant life that cannot be seen by the unaided human eye.

Watch The Green Planet: Seasonal Worlds on WITF TV Wednesday, July 20 at 8pm or stream it for free starting July 21 until August 18 through the PBS Video app.
