heliotropism: a diurnal response where plants track the motion of the sun.
Ginger started these plants inside for her garden, and it hasn't gotten quite warm enough to put them outside. Everynight before I go to sleep, I turn them away from the sliding glass doors, and everyday when I come home, they have turned and "grown" towards the sun. In an amazingly geeky bit of trivia, heliotropism was recorded by Leonardo da Vinci in the early 1500's.
