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.

LATIN: Dioscorea polystachya aka Dioscorea opposita aka Dioscorea batatas
ZONE HARDINESS: 4-11
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.
