Thousands of Potatoes in the Peruvian Andes
When you think of a potato, you may picture a plain, brown one. In the mountains of Peru, potatoes come in a surprising rainbow. Some are purple, some are red, and some are yellow or pink. Some are round, some are long, and some are twisted like knobby fingers.
Farmers in the Andes have grown potatoes for thousands of years. Peru is home to thousands of different kinds. Why are there so many? The mountains have many different heights, and each height has its own weather. A farmer can plant one kind on a warm slope and another in a cold, windy field high above. Each kind does best where it fits.
Cold weather helped the farmers invent a clever way to keep potatoes for a long time. They leave small potatoes outside on freezing nights. In the day, the sun warms them and people stamp out the water. After days of freezing and drying, the potatoes become light, hard, and dry. This food is called chuno, and it can be stored for a long time.
Today, many families still grow several kinds of potatoes in one small field. If bad weather hurts one kind, another may still grow well.
