Wikipedia description: The Secret Life of Plants (1973)

The Secret Life of Plants is a book by Peter Tompkins and Christopher Bird, described as “A fascinating account of the physical, emotional, and spiritual relations between plants and man.”

The book explores the idea that plants may be sentient, despite their lack of a nervous system and a brain. Recent research has been interpreted as suggesting that plants may in fact ‘remember’], but this interpretation has been disputed. This sentience has purportedly been observed through changes in plants’ conductivity, as through a polygraph, as pioneered by Cleve Backster. The book also contains a summary of Goethe’s theory of plant metamorphosis. The book delves deeply into such unconventional topics as the aura, psychophysics, orgone, radionics, kirlian photography, magnetism/magnetotropism, bioelectrics, dowsing, and (more conventionally) the history of science.
