Per Wikipedia Heliotropism is the motion of plant parts (flowers or leaves) in response to the direction of the Sun. In this anisotropicplus video I documented heliotropism in one of my sunflower plants by taking a photograph every hour through the day and went a step further by continuing to take photos through the night. The sky was clear day and night. It is a fascinating effect and is like a robotic plant that moves based on sensory input. https://en.wikipedia.org/wiki/Heliotropism
