Sweet Potato Facts & Trivia
The Sweet potato is believed to have originated in South or Central America, but the true origin has not been clearly identified as early evidence of it can be found in multiple regions of the world. Evidence of its cultivation in Peru dates back 4000 years before the Spanish arrival in the 1490’s, and taxonomic studies indicate that historically the densest collection of genetic diversity of the Sweet potato crop is found in Central America.
In the United States, the terms Sweet potato and yam are often used interchangeably, though, in reality, they are botanically not the same thing. The first Sweet potatoes produced commercially in the United States were firm and white-fleshed types. When the orange-fleshed variety moved into the commercial market, producers and shippers needed a means to differentiate them from the white-fleshed variety. The name yam was picked as a result of the Sweet potato’s similar appearance to that of the African root vegetable Nyami, translated as yam in English. Though Sweet potatoes are commonly sold as yams in grocery stores today, the U.S Department of Agriculture does require that these yams also be labeled as Sweet potatoes. Additionally, as a result, many processed canned and frozen orange Sweet potato products in the United States are sold under the name yam as well.
