This is an improved selection with particularly large bulbils for the species. It is the same strain used in the Experimental Farm Networks community-supported yield trial. If you are interested in participating in the research there is a possibility of receiving this material from EFN for free.


Dioscorea polystachya is a vining perennial vegetable with edible tubers and bulbils aka 'yam berries'.


5 bulbils are in each 'seed' pack.  Every bulbil received will not necessarily be their maximum size.  Growing from bulbils creates clones, so even a smaller-sized bulbil will have the same genetics from this improved selection.

Product Overview

LATIN: Dioscorea polystachya aka Dioscorea opposita aka Dioscorea batatas


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: 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. In chinese medicine the tubers are a longevity tonic named Shan Yao.
