Can anyone help me id this vine? The closest I can come up with is Sweet Potato Vine (Ipomoea batatas, somewhat bur different!)except that it's not quite a match. The photos are of immature leaves and the color ends up to be similar to a kiwi. It is tuberous, vigorous as all get out, grows fast and Japaneses beetles adore it. Seems to prefer shade and it does not appear to be woody.

But, unlike a sweet potato it is quite hardy and survived 7b freezes in a small pot so pot bound there was barely any dirt in it. Previous homeowners had planted it in a pot underground which I dug up - it was everywhere. It also did much better in the fall when the weather cooled. Then it really took off. It was a monster of a plant like something out of Steven King. Just grew and grew...It laughs at weed killer and loves to be run over by a lawn mower. This year I put it in a big pot hoping to keep it in control. Thank you.
