Research finds plants can do math and know what time it is

Geek: Light is everything to a plant. We’ve known for a long time that light is their form of sustenance and warmth, and even that it helps them track through the seasons. It makes sense that they would coordinate their annual cycles in reference to sun — but can a plant also have an awareness of the time of day? It’s becoming increasingly clear that not only do plants know and care what time it is, but that we can exploit that tendency to make them better for us — even after they’ve been ripped from the soil.
