Front: In the 1960s Cleve Backster, an interrogation specialist with the CIA, conducted research that led him to believe that plants can communicate with other lifeforms. In February 1966, he tried to measure the rate at which water rises from a philodendron’s root into its leaves. Because a polygraph can measure electrical resistance, which would alter when the plant was watered, he attached a polygraph to one of the plant’s leaves. Backster stated that, to his immense surprise, “the tracing began to show a pattern typical of the response you get when you subject a human to emotional stimulation of short duration”
