Plants Matter explores how plants and people live together. This is not only a book about the importance of plants and how people use them, but it argues also that knowing the world is achieved-with plants. In addition to populating the landscape, plants alter human physiology in multiple material ways, through gatherings or through sensorial conversations using the chemistry of taste, perfume, colour, sound and textures. The chapters gathered in this volume offer a range of interdisciplinary perspectives that use ethnographic and ethnobotanical information to explore how the behaviours and capacities of certain plants around the world have enticed, excited and even seduced people to pay attention.
