A study looking at Evening Primroses concluded that the plants could sense the vibrations of a buzzing insect and temporarily increased the concentration of sugar in their flowers’ nectar in response. How amazing is that?!
Flowers can hear buzzing bees—and it makes their nectar sweeterBut for plants exposed to playbacks of bee sounds (0.2 to 0.5 kilohertz) and similarly low-frequency sounds (0.05 to 1 kilohertz), the final analysis revealed an unmistakable response. Within three minutes of exposure to these recordings, sugar concentration in the plants increased from between 12 and 17 percent to 20 percent.
A sweeter treat for pollinators, their theory goes, may draw in more insects, potentially increasing the chances of successful cross-pollination.
