They are highly nutritious and can be described as a perfect food. Huaiyushan Potatoes have a long history of cultivation within Yushan County and are a major local crop. These potatoes are the result of careful selection by local farmers and natural evolution. Historical records indicate that in the late 19th century, they were brought to Huaiyushan by Dr. Tooker, a missionary from the American Northern Presbyterian Church, and planted in the local temple at that time. Through years of potato farming practice, local farmers accumulated rich experience in cultivation and breeding. Over time, this gradually led to the development of a potato variety representative of high-altitude regions.
