We've all seen plants above the ground, but how often do you dig one up and look at the roots? In this new book from authors Peter Tompkins and Christopher Bird, they do just that, diving into the world of plants that is hidden from our daily view. Recent scientific discoveries have uncovered the extent to which plants have actually attained something we might call sentience: they can communicate with each other and adapt to changing circumstances, distribute resources amongst themselves and help each other out. Tompkins and Bird turn our understanding of this verdant world upside down, providing new insight into a world so ubiquitous and commonplace as to be easy to overlook. An essential read for any gardener or amateur biologist or ecologist.
