Deadly nightshade

The name says it all — both the foliage and the berries of this plant are extremely toxic. Deadly nightshade has a long, colorful history of use as a poison, but what many people don't realize is that the nightshade family includes common food plants, including potatoes, tomatoes, eggplants and chili peppers.

In fact, all of these plants contain toxins — usually in their foliage — that can be harmful. In particular, humans and pets should avoid potato and tomato foliage and vines in the garden.
