Why do plants grow in different places? How do they adapt to different environments? And what makes them different species? Those are the questions that drove biologist David Lowry to begin a 20 year study of a shape-shifting plant called the yellow monkeyflower. It begins with a road trip, and ends up questioning everything you think you know about the definition of species. Get ready for a wild, plant-fueled ride into science!
