The filmmakers from NOVA set out on a quest to find the world's earliest flower in a special documentary that explores the plant form that has long been at the epicenter of human existence. Flowers show how we feel about others, fill our gardens with beauty, and help to provide us with food and medicine -- yet scientists have yet to discover a definitive answer to the question of how they evolved. When a fossil that had previously bloomed during the age of the dinosaur surfaced in China's Hengduan Mountains, the controversy that followed baffled and intrigued scientists on every continent. It would appear that this area, commonly referred to as the "Mother of All Gardens," was the birthplace of every form of flower from the clematis to the primrose. With this release, curious nature lovers can follow filmmakers as they explore the mysteries of the most spectacular flowers on the planet.
