We report what we believe is the first experimental limit placed on plant biomagnetism. Measurements with a sensitive atomic magnetometer were performed on the Titan arum Amorphophallus titanum inflorescence, known for its fast biochemical processes while blooming. We find that the magnetic field from these processes, projected along the Earth s magnetic field, and measured at the surface of the plant, is 0.6 muG.
