Potatoes come from the ground, the edible tubers on the roots of the potato plant (Solanum tuberosum). They are grown in many parts of the world. The Spanish were the first Eu â¦ ropeans to see potatoes. The tubers were cultivated in South America, in Peru and Chile.
Potato plants grow wild all over South America and as far north as Colorado and Nebraska in North America.

Sometime around 8000 BC, in the Andes Mountains in South America, people began to farm potatoes as well as gathering them.
