Kingdom of Plants 3D

David begins his journey inside the magnificent Palm House, a unique global rainforest in London. Here, he explores the extraordinary plants that are so well adapted to wet and humid environments and unravels the intimate relationships between wet zone plants and the animals that depend on them. It was in the wet zones of the world that plants first moved on to land and in the Waterlily House David reveals how flowers first evolved some 140 million years ago. Watching a kaleidoscope of breath-taking time-lapses of these most primitive of flowers swelling and blooming in 3D, he is able to piece together the very first evolutionary steps that plants took to employ a wealth of insects to carry their precious pollen for the first time. David discovers clues to answer a question that even had Charles Darwin stumped: how did flowering plants evolve so fast to go on to colonise the entire planet so successfully? He marvels with signature enthusiasm at orchids, plants at the very pinnacle of the plant tree of life. Many of these captivating flowers evolved to be pollinated by a single insect species and in doing so developed such complicated contraptions of pollination it's hard to imagine anything more beautiful. One orchid even looks like a bee.

David uses the latest 3D technology to explore a world beyond the confines of our human senses. He begins with the secret world of plant movement and uses sinister carnivorous plants to show just how active plants can be. Bladderwort utricularia is a pond-dweller that is among the fastest known, its traps snapping shut in less than a millisecond. As the seasons change, David demonstrates how plants operate on a different time scale to us; how they modify their lives according to the time of year. We discover insects' hidden links with plants, both as pests and pollinators. UV-sensitive 3D cameras reveal the invisible alter-ego of plants and their flowers' mesmerizing patterns; a parallel-dimension of strange colours and stunning patterns through which plants communicate with them. With the aid of visual effects, David steps among the swirling vortices of plant scent; communication signals with which plants are inextricably plugged in to the natural world. And using a tuning fork, he demonstrates how plants and insects can even communicate with music. As Autumn envelopes the Gardens, fungi reveal themselves not as the enemies of plants but their vital allies. In Kew's musty Fungarium, David discovers a specimen that has the power of mind control and another that lives underground where it has grown to be so big it can be counted as the largest single organism on the plant. It is 6 times bigger than Kew Gardens itself. David concludes the film in the Princess of Wales Conservatory, where he meets an old friend, the great Titan Arum. At 8ft tall, it is the largest flower in the world and a plant he remembers from a previous filming trip to Sumatra. Using heat sensitive cameras, David reveals the Titan Arum's secrets, how it uses a combination of heat and powerful scent to punch a hole in the stratified layers of air in the rainforest, enabling it to broadcast its presence across vast distances.

David discovers the plants that have evolved to shed their dependency on water enabling them to survive in the driest environments. The story begins at midnight in midsummer as David steps into the Princess of Wales Conservatory to witness the extraordinary nocturnal blooming of a cactus. The Queen of the Night, with its giant flowers, is the centre piece of a stunning symphony of cacti blooms that burst open in the desert (and at Kew) at night. In a mesmerizing 3D slow motion sequence, we discover the extraordinary connections between cacti and their natural pollinators: bats. The scene typifies the unique splendour of the 3D experience as bats seem to fly out of the screen and into the viewers' living room. As the sun rises, David meets other amazing plants. Species like the Century Agave, which grows steadily for over 50 years, only to then flower itself to death with one mighty telegraph pole sized bloom which literally bursts out of the roof of Kew's green house. Cracking the code to plants' survival strategies is the key to protecting their future and Kew have built a high tech long-term solution fifty miles south of the Gardens. Described as mankind's ultimate insurance policy, and with 10% already cryogenically housed, the Kew Millennium Seedbank has the capacity to store seeds from every remaining species of plant on the planet, thus ensuring that no plant need ever go extinct again.
