Kudzu hands down, because almost nothing will kill it, but it destroys everything in its path.

well im voting for oriental bittersweet, TONS of seeds and very high germination rates, Kudzu few if any seeds germinate, Oriental bittersweet STRANGLES kudzu merly covers but doesn't strangle (i think) If kudzu becomes wiped out then there is not hardly near the seed bank that OB has, anyway just a few of my thoughts,, I want more opinions on this what is yours.

So covering is strangling? If covering doesn't involve intertwining then how does Kudzu grow 40 feet up into trees?

Kudzu grows around trees, oriental bittersweet strangles by TIGHTLY growing around trees
