The Secret Life of Plants

The Secret Life of Plants (1973) is a book by Peter Tompkins and Christopher Bird, which documents controversial experiments that claim to reveal unusual phenomena associated with plants, such as plant sentience and the ability of plants to communicate with other creatures, including humans. The book goes on to discuss philosophies and progressive farming methods based on these "findings".

It was heavily criticized by scientists for promoting pseudoscientific claims. Later editions were published with the subtitle A Fascinating Account of the Physical, Emotional and Spiritual Relations Between Plants and Man.
