摘要

Sweet potatoes (Ipomoea batatas, Zones 10-12) are fun and very easy to grow as long as you have enough space for their vigorous vines. At season's end, the plants will produce delicious and nutritious roots that can store well for up to a year or longer. Though many gardeners think of this as a crop that needs warm weather and a long growing season, sweet potatoes can be easily grown wherever there are at least 90 to 100 frost-free days.
