Peanuts originally came from South America, most likely Brazil or Peru, but they now are grown in many countries around the world. Peanuts are obtained from a mature Arachis hypogaea plant, which looks like a bush.
The peanut is not a nut, despite its name, but it is a legume instead. Peanuts are commonly eaten raw after one breaks open the shell. They can also be roasted or blended into peanut butter. The peanut plant blooms once a year and grows to a height of approximately 12 to 20 inches. Peanuts can be picked off the plant by hand or be harvested using a large mechanical harvester.
