Dig sweet potatoes carefully as their skin is thin and they will bruise easily. It is best to wear gloves when handling them. Do not leave the roots exposed to direct sunlight with temperatures above 90 degrees F. for over 30 minutes as they will sun-scald and be more susceptible to storage rots.
An edible tuberous root, much prized in North America, a staple article of food in all the southern states, and also much consumed in the North. The Sweet Potato plant is a trailing vine of the morning-glory family. The branches root at the joints. The edible tubers are borne close together under the crown and unlike the common potato they do not bear definite “eyes.” The varieties differ greatly in length of vine and the “vineless” Sweet Potato has a bushy habit. Good commercial varieties that are well cared for rarely bloom, and even then the flowers may not produce seed. The plant is tender to frost. The species is widely distributed in tropical regions but is supposed to be of American origin.
