The vine that's trying to take over the world (and doing a darn good job in the south). It will cover anything and everything. When we came back to Alabama in 1990, my farm had been just sitting for almost 30 years. EVERYTHING that was left was covered with kudzu. Several 'outbuildings' - you couldn't see them. If I hadn't known where they were....
The stuff can grow a foot a night (that's 12"). It was imported and planted years ago to help with erosion - and by golly - it does a great job of that.
Fortunately these pictures were NOT taken on my property. The first one is actually a street in town and the one below was the ball field at the Community Center (less than a city block from me). It's kinda scary too, you don't want to try and walk in it. Obviously very long twisty vines.
Mine is gone! That's why we got goats to begin with. They love it. It took them about three years to completely erradicate it, however, it could come back quite easily as it's so close.
