Drag the plant photo to the place of its origin. Use the shaded squares on the map as targets for the places where you should drag the photos. If you drag the photo to the wrong place, it will jump back to the bottom of the map. The shaded areas do not represent the exact location of origin, just the region of the world where the plant originated. The shaded areas that cover more than one region indicate that the plant originated in an area covering both regions, not the exact place that the shaded area marks.
