Is it possible that plants are smarter than we think? They are among the world's oldest and most successful organisms and represent some of the strangest and longest living life forms on the planet. Stunningly diverse, plants have served us in many critical ways, from providing food, shelter and clothing to life-saving medicine. And yet we know very little about them. A luscious exploration of the natural world, Smarty Plants effortlessly integrates pioneering science with a light hearted look at how plants behave, revealing a world where plants are as busy, responsive and complex as we are. From the stunning heights of Utah's Great Basin Desert to the rainforests of Canada's west coast, Smarty Plants follows lead scientist and ecologist JC Cahill as he treks the green world and discovers that plants are a lot more like animals than we ever imagined.
