Purple yam seeds produce vigorous, warm-season plants with a climbing, vining growth habit and broad green foliage. This type is well suited for garden beds and open spaces where support structures such as trellises can be provided. It grows best in consistently warm conditions with full sun and performs well in loose, fertile, well-drained soil.
