Distinguishing Yams from Sweet Potatoes

A common source of confusion exists between yams and sweet potatoes. Despite their similar appearance, they are not closely related. Sweet potatoes are not a type of yam, and vice versa. In many instances, what is sold as a "yam" in grocery stores, particularly in North America, is actually a sweet potato.

Distribution and Habitat:

Yams are a staple food crop in many tropical regions around the world.

  • Africa
  • The Caribbean
  • The South Pacific
  • The Americas

Yams are grown as annual or perennial vines.
