According to an expert on lie detectors, Cleve Backster, founder of the FBI's polygraph unit, plants can feel, plants have ESP, plants are experts at detecting lies, plants can recognize people, plants have remote sensitivity and more.
Using lie detector tests, Backster claimed that everything in the universe is interconnected and capable of producing emotional responses. For example polygraph was hooked to the plant. When Ceve Backster manged to create perception of a threat to the plant, polygraph readings would jump on the scale at the time of creation of the thought (in which he would imagine plant's leaves burning). He didn't actually need to burn the leaves of the plant, past experience of such an event and the intention of the experimenter to repeat that act was enough to spike the reading of the lie detector.
Backster's biocommunications work is most famously discussed in The Secret Life of Plants by Peter Tompkins and Christopher Bird.
