In 2018, Tel Aviv University Researcher Lilach Hadany discovered that evening primroses could hear. She played different sounds to the plants, such as white noise, high frequency sounds, or no noise at all – and found that when she played recordings of bees, within three minutes the plants would increase the sugar concentrations of their nectar from 14.5 percent to 20 percent. The theory is that this would cause the bees to linger longer at the flower, and thus increase the chances of pollination to occur. The study of plant hearing is called phytoacoustics. --- Source: [[Cornerstones]]
