A personal and highly original take on the history of six commercial plants, Seeds of Changeilluminates how sugar, tea, cotton, the potato, quinine, and the cocoa plant have shaped our past. In this fascinating account, the impassioned Henry Hobhouse explains the consequences of these plants with attention–grabbing historical moments.
