Geography/History
Amarilla Tumbay potatoes are native to South America and are thought to be descendants of wild varieties that grew naturally throughout the highlands of the Andes mountains.

The variety has also won awards abroad for its flavor in various potato competitions, including the Potato Exhibition in Crevan, France 1993.
