花，挑戰不可能。雖然外表弱不禁風，但花是強悍的戰士。它們的歷史充滿征服地球的戰績。目前，地球所有植物物種之中，有花植物佔了九成。花在生命之樹的哪個位置？何時在地球誕生？為何種類如此繁多？它們擁有什麼戰無不勝的超能力？
新一代科學家正努力回答這些問題，解決花的不解之謎。從非洲沙漠到阿爾卑斯山的山頭，他們的發現正徹底改變我們對有花植物的起源和數量暴增的了解。
英國生物學家埃德維·莫瓦，以電子顯微鏡觀察木槿花瓣，發現這種植物擁有一種奇妙的能力，可以操縱光線，是吸引授粉昆蟲的無敵武器。以色列的進化理論家妮勒哈德尼，則利用最先進的技術研究花朵，揭示它們有著意想不到的超能力—感應聲音。
在蘇黎世植物園和白朗峰，生物學家科里亞.謝斯圖和塞巴斯坦.拉凡爾努力研究花朵為何有著人種類繁多的繽紛色彩和形狀。他們的研究顯示，授粉者和地理分隔對開花植物的種類迅速增加起著重要作用。
在新喀裡多尼亞和納米比亞，遺傳學家瓦萊麗.寶蒂和弗朗索瓦·帕西帶領團隊，搜索史前植物，希望破解這些植物的基因密碼，揭開有花植物起源的秘密。
以上種種發現，令科學家可以追溯地球植物生命的奇妙歷史，並解開自然界其中一個最棘手的謎團—花的不解之謎。

Flowers defy the impossible. Under their seemingly fragile appearance, they’re fierce fighters. Their  history is that of their dazzling conquest of the planet. Today, they represent 90% of plant species. This utter domination has intrigued scientists for centuries. According to Charles Darwin, “The rapid development of flowering plants is an abominable mystery.” What place do flowers hold in the tree of all living beings? When did they first appear on Earth? How can we explain their prodigious diversification? And what are the superpowers that make them invincible? To answer these question and solve the abominable mystery of flowers, a new generation of scientists is hard at work. From the African deserts to the summits of the Alps, their discoveries are revolutionizing the way we conceive the origin and expansion of flowering plants.
In the UK, biologist Edwige Moyroud is observing hibiscus petals under an electronic microscope. Her work has highlighted fascinating powers that allow the plant to manipulate light beams, an unstoppable weapon to attract pollinating insects. In Israel, evolution theoretician Lilach Hadany is studying flowers using state-of-the-art technology in order to reveal an unsuspected superpower: Their capacity to detect sounds.
At the Zurich Botanical Garden and in the Mont Blanc massif, biologists Florian Schiestl and Sébastien Lavergne are trying to understand the dizzying diversity of shapes and colors in the floral world. Their research shows the role of pollinators and of geographical isolation in the lightning-fast diversification of flowering plants.
In New Caledonia and Namibia, geneticists Valérie Burtet and François Parcy are leading expeditions in search of prehistoric plants. Their hope is that the deciphering of their genetic code will unlock the secret of the origin of flowering plants.
Thanks to these discoveries, scientists are now able to retrace the fascinating history of vegetable life on Earth and to solve the abominable mystery of flowers, one of nature’s most tenacious enigmas.
