It’s interesting to see how plants react to light isn’t it?
I’m sure you’ve looked at your house plants or various plants in your garden and saw that they were facing the sun, or that the flowers were open fully in full sun. However, at night or when not in full sun you might have also noticed flowers closing or plants leaves turning to try to capture whatever small bit of sunlight they could reach.
Here’s a time lapse video of an Elephant Ear houseplant reacting to the sun. It’s facing into the plant owners home in the beginning but watch what happens as the window that the plant is near becomes brighter and brighter as the sun comes through it.
