Potato Seeds - Dioscorea

Dioscorea seeds produce vigorous, warm-season vining plants commonly grown as annuals or tender perennials depending on climate. Plants develop long, climbing vines and form underground tubers in loose, well-drained soil. Dioscorea grows best in warm climates with a long growing season and consistent moisture. It is suitable for garden beds and open planting areas where space and vertical support are available. Plants adapt well to fertile soils and benefit from steady watering and full sun exposure during active growth.
