It is important to distinguish "yam plant" from the vegetable called a "yam" in many grocery stores, particularly in North America. What is often labeled as a "yam" in the U.S. is typically a variety of sweet potato (Ipomoea batatas), which is from a different plant family entirely. A true "yam plant" belongs to the genus Dioscorea.
