Spoiler The best of intentions don't always have a happy ending. Covering over 7 million acres of the southeast this vine has a checkered past. Growing at a rate of up to 60 feet a year it grows everywhere and to borrow from Thurber's story "The night the ghost got in," the night the vine got in is a distinct possibility as it could grow a foot in one night.

Spoiler Names found for the plant are "a mile a minute vine", or a Glad it is too cold up here in Washington to grow year round. In eHOW they say it can grow up to 18 inches a day, so thats my answer. Too bad the Kudzu Growth Fund did not grow as fast as its namesake.
I forgot that part, but they do have tap roots over 50 ft deep. I have read that putting goats in to pasture with them can kill them off... I know a state park that could use a LOT of goats to eat those things.
Spoiler Kudzu vines grow up to one foot a day during the months of summer and as much as sixty feet in the growing season. A native of China and Japan, kudzu vine was introduced to the United States in 1876 during the Centennial Exposition that was held in Philadelphia to celebrate the nation's 100th birthday. To celebrate the centennial, the Japanese government created a beautiful garden exhibit filled with native Japanese plants, including kudzu. Unaware of its potential as an invasive plant, American gardeners soon began to grow kudzu for its attractive glossy foliage and heavily-scented blossoms similar to wisteria. Now, years later many people are looking for a way to control Kudzu.
