About Japanese Arrowroot

Kudzu is a semi-woody, twining, aggressive vine that is native to Asia and Northern Australia. It was introduced in the United States in 1876 at the Philadelphia Centennial Exposition. In 1933 the U.S. Soil Conservation Service introduced a variety of Kudzu, Pueraria montana var. lobata, for erosion control and agricultural purposes. In the 1950s it was declared a common weed and in the 1970s it became a noxious weed.
