But people in Europe did not like this strange vegetable. Some people thought that if you ate potatoes, your skin would look like the skin of a potato. Other people could not believe that you ate the underground part of the plant, so they ate the leaves instead. This made them sick because there is poison in the leaves. Others grew potatoes for thir flowers. At on time in France, potatoes flowers were one of the most expensive flowers. Marie Antoinette, the wife of King Louis XVI, wore potato flowers in her hair.
