Product Overview

COMMON NAMES: Japanese Mountain Yam, Yamaimo

LATIN NAME: Dioscorea japonica


PLANTING: Store bulbils at room temperature until ready for planting. Plant in spring as you would a seed, in pots or directly into the ground.  Unlike a seed, they are clones, producing genetically identical plants. Provide a trellis.

HARVESTING TUBERS: Dioscorea japonica is known for being easier to harvest than the deep tap rooting varieties of Dioscorea polystachya/opposita.  This selection's tubers branch out from the main stem forming a cluster of smaller sized tubers. 

HARVESTING BULBILS: Grow up a trellis such as an arched cattle panel. Once ripe, place a tarp on the ground and shake the trellis, thereby raining bulbils for easy collection.

EDIBILITY: Bulbils can be cooked as bite-sized potatoes. They taste good, and once established can have prolific harvests. The tubers are delicious.
