You are bidding on 5 seeds of Vitis riparia.  

This beautiful vine is one of the hardiest species in the genus.  This plant covers itself in clusters of the small but sweet grapes, that are good for eating fresh, although they can also be used to make jelly, juice, or wine.    They are hardy to at least USDA zone 4.  This is an excellent plant for ornament as well as fruit production.  These plants would make excellent additions to your rare plant collection, or just make a unique statement in your yard.

HAPPY GARDENING :)
