An augmented reality (AR) plant content system is provided. The AR plant content system may detect an object in a real world scene that corresponds to a plant. The AR plant content system may generate care instructions for the plant that include AR graphics that are displayed as overlays of the real world scene. The AR plant content system may also track the motion of objects in the real world scene to determine that plant care events have taken place, such as watering the plant or pruning the plant. A plant inventory may be produced that includes care instructions and a log of plant care events for plants that correspond to one or more users.
