Kudzu (Pueraria montana var. lobata) is a perennial vine that is well adapted to the southern and southeastern United States. The plant is native to Japan and southeast China, and was first introduced into the U.S. at the 1876 Philadelphia Centennial Exposition. From the early 1930s to the mid-1950s, public and private landowners were encouraged by the Soil Conservation Service to plant kudzu to reduce soil erosion. Kudzu currently infests about 7.4 million acres in the U.S. and occupies about 123,000 new acres annually.

Kudzu is well established in the eastern and southern portions of the U.S. In the West, it was reported and subsequently eradicated in Clark County, Washington in 2011; and is reported in four counties in Oregon (EDDmapS 2017).

Once established, kudzu grows at a rate of one foot per day with mature vines as long as 100 feet. Known as “the vine that ate the South”, kudzu can easily overtake trees, abandoned homes, cars and telephone poles.
