Murasaki

Murasaki presents purple skin over white flesh, a visual contrast to the common orange-fleshed sweet potato. The flesh is dry and extra starchy, cooking down with a rich, nutty flavor and high sugar content that reads as delicate sweetness rather than the wetter sweetness of orange types. It is also noted for its fiber and vitamin C content. This combination of appearance, texture, and flavor gives it a distinctive profile that has made it a favorite among chefs and nutritionists.

Its dry, starchy white flesh suits baking, boiling, or mashing.

As a Japanese-type sweet potato, Murasaki needs a longer growing season to mature, which can challenge northern growers, though its eating quality is considered unbeatable. It also stands up well against two soil-borne threats, Fusarium root rot and the southern root knot nematode, problems that can otherwise limit root quality and yield.

Despite its Japanese-sounding name, Murasaki was bred at the Louisiana Experiment Station, with development beginning in 2001 and commercial release to growers following some years later, in 2008. It originated in Louisiana and is now also widely grown in California. The name Murasaki means purple in Japanese, reflecting how its appearance and taste echo Asian sweet potato varieties rather than any actual Japanese origin.
