Pueraria montana var. lobata, commonly called Kudzu, is a deciduous twining vine that is noted for its rapid and invasive growth. It is native to Asia where it has long been cultivated for its starchy tubers (food crop and medicinal uses) and for its hemplike fibers. It was first introduced into the U.S. as an ornamental landscape planting at the Japanese Pavilion at the Philadelphia Centennial Exposition of 1876. During the first half of the 20th century, before its aggressive nature was fully understood, it was widely planted in the southeastern U.S. as a forage crop and for erosion control. In Missouri, it was planted along highways for bank stabilization. Over the past 100 years, it has escaped cultivation and naturalized in many areas of the eastern U.S. from Connecticut to Oklahoma south to Florida and Texas, becoming perhaps the most infamous invasive weed in the country. Although early on the Federal Government promoted its use, in 1997, it was classified as a noxious weed under the Federal Noxious Weed Act of 1974. It is currently the target of numerous extinction programs. Kudzu can produce prodigious amounts of foliage in optimum conditions, growing up to a foot per day and to 100 feet in a single growing season. The vines spread by rhizomes and by stems that root at the nodes. When left unchecked, particularly in warm winter climates, vines can cover shrubs and tree canopies, choking out and killing entire plant communities. Vines have also been known to collapse buildings and bring down utility poles. The voracious nature of this vine has given rise to a number of tongue-in-cheek common names such as “the vine that ate the South”. This is a tuberous vine that establishes huge taproots. It forms a crown at the soil level from which up to 30 vines may grow, with individual vines extending up to 100’ in length and to 1-4” in diameter. Vines are hairy and are clad with compound, trifoliate green leaves, sometimes lobed. Pendant racemes of fragrant, pea-like, purple flowers may appear in late summer to early fall on plants growing in sun. Flowers are uncommon in the northern parts of its growing range, however. Flowers give way to flattened, bean-like, hairy seed pods (to 2” long). Synonymous with and formerly known as Pueraria lobata.

Genus name honors Swiss botanist Marc Nicolas Puerari (176-1845).

Specific epithet means pertaining to mountains.
