Botanical Families

Different Botanical Families

Botanically, yams belong to the Dioscoreaceae family, while cocoyams belong to the Araceae family. This botanical distinction is significant, as it influences not only the appearance and taste but also the cultivation methods and growing conditions of these tuberous vegetables.

Growing Conditions

Varied Cultivation Requirements

Yams and cocoyams thrive in different growing conditions. Yams prefer tropical climates with well-drained, sandy soil, and they are often propagated using vine cuttings or tubers. Cocoyams, on the other hand, are adaptable to both tropical and subtropical climates, and they prefer moist, fertile soil. They are typically grown from corms or cormels.
