🍠🌱 The Best 20 Varieties of Yam to Grow: Tips, Facts, and Information
🌿 Introduction: Understanding Yams Before You Grow Them
True yams (Dioscorea species) are not the same as sweet potatoes. They are climbing plants that produce large underground tubers and are widely grown in tropical and subtropical regions.
Yams are valued for being:
✔ highly productive
✔ long-storing
✔ nutritious and filling
✔ adaptable to different soils
While yams need warm temperatures and a long growing season, some varieties can be grown successfully in greenhouses, polytunnels, or warm UK summers with protection.
