Wild potato vine?
This vine is growing all along the edge of my property (it would take over if I didn't keep it mowed back). A neighbor said it's a wild potato vine. I did a search and aren't convinced, as that vine has white morning glory type flowers. I've never seen a flower on this vine. The fruit grows along the stems and varies in size from a pea to a baking potato. Does anyone know what this actually is, and is the fruit edible?
