|discussion=<p>The tubers of Solanum jamesii have been gathered as food by Native Americans, and starch grains identified as S. jamesii from stone tools in Utah form the earliest evidence for the use of potatoes in North America (L. A. Louderback and B. M. Pavlik 2017). All other parts of the plant are toxic.</p>
