'When Peter Tompkins and Christopher Bird wrote The Secret Life of Plants (1975), many critics labelled their attempt to prove a spiritual link between people and plants as mystical gibberish, with a New York Times review chiding the authors for pandering to charlatans and amateur psychics. The review noted that although Tompkins and Bird made a fascinating case for plant sentience ‘suspended in the aspic of their blarney, it all looks equally improbable’. In the ensuing decades, more books have been published on the life of trees and their relationship to humans, some of which have sold well and been enthusiastically received by critics. Peter Wohlleben’s The Hidden Life of Trees: What they feel, how they communicate – discoveries from a secret world (2016) topped bestseller lists and earned him a flattering interview in the profile pages of The New York Times.'
