In the Southeastern United States, Kudzu vines grow so fast that it seems you can almost see them grow. Still, it is not the fastest growing plant. Which plant is?

Answer:

Bamboo is the fastest growing plant. Some species of bamboo can grow more than 24 inches a day, twice as fast as the 12 inches a day for kudzu. Of course the bamboo is not growing that fast outwards, in all directions, so it does not engulf the landscape as kudzu does.
