Kudzu-peuraria montana can grow up to a foot a day. It covers over 7 million acres in the U. S. I remember going to my grandpa Lawrence Dulaney's and when you turned off the 25 at East Fulton Church (White Church) on Dulaney Wilemon road, Kudzu covered all the old buildings and hung from dead trees that they had overcome and killed. It is a haven for snakes and all kinds of critters. However its good to stop a hill side for washing away.Cows like to eat it, alot of people hate it, and I would have to agree it is almost impossible to control. It kills and destroys and takes no prisoners. However I just think its PURTY!
