Often seen on the "Yukon Gold" variety of potatoes, are small green fruits that strongly resemble young tomatoes. The potato fruits are poisonous because they contain high amounts of solanine. When the fruit is cut in half, the view of the inside shows that it is lined with potato seeds. These seeds can be harvested and saved for next year's crops.
