Chapter 5

Don’t be amazed! We too are carrying out many experiments of this kind and they all point to one thing: plants have memory. They are able to gather impressions and retain them over long periods. We had a man molest, even torture, a geranium for several days in a row. Another man took care of the same geranium. When we electroded our instruments to the plant, what do you think? No sooner did the torturer come near the plant than the recorder of the instrument began to go wild. The plant didn’t just get “nervous”; it was afraid, it was horrified. If it could have, it would have either thrown itself out the window or attacked its torturer. Hardly had this inquisitor left and the good man taken his place near the plant than the geranium was appeased, its impulses died down, the recorder traced out smooth–one might almost say tender–lines on the graph.
