You are bidding on 5 seeds of Vitis labrusca Concord.  

This vine covers itself in clusters of purple grapes that can be used to make wine, although they are also good for eating fresh, and they can also be used to make jelly or juice.    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 :)
