“What is this beautiful plant?” I asked my husband as we walked down the street in Nashville. He took a photo, reported it was the downy thorn apple and it was highly poisonous, prompting me to wash my hands immediately.
He got that information from using the Picture This app, which bills itself as a botanist in your pocket. Take a photo of any of 10,000 plants in its database and it tells you what kind of plant it is and its properties. It will also diagnose any issues that the plant may have and what to do about it.
