I live in southeastern VA and wish to identify a vine growing in an uncleared area of my property. The vine has fairly large grape like leaves. The berries are small, (1/4"-3/8") in diameter, each with one seed, similar to a very small cherry seed or pit. The berries hang in clusters at least 4" in length. The berries are green when immature and ripen to black/purple. The flesh is similar in color and texture to the flesh of green grapes. The vine is quite large, reaching into the tree canopy. I am new to the property and have not seen the flowers. I don't know if this was originally a domestic plant that has gone wild or if it is a noxious, invasive pest. I hope that you can tell me if it is something I should attempt to cultivate or something that needs to be erradicated.
