Writer. Above: Kudzu covers a hillside in Japan. Kudzu is a fast growing vine that coils and climbs anything in its path. The plant was first brought to North America in 1876 to landscape a garden at the United States Centennial Exposition in Philadelphia, Pennsylvania. Plant Description: Kudzu is a deciduous vine with long, thick rhizomes, hairy stems, and trefoil leaves. However, you can make a variety of tasty dishes and drinks from fresh and powdered kudzu. [7] For sexual reproduction, kudzu is entirely dependent on pollinators. A different survey found twenty-five different species of insect feeding on the kudzu. [7] When boll weevil infestations and the failure of cotton crops caused farmers to abandon their farms, kudzu plantings were left unattended. Its aggressive and smothering growth habit makes it a serious weed problem in many noncrop environments including forests, rights-of-way, and natural areas. [20] In the United States, kudzu is extensively reported in Alabama, Arkansas, Washington, D.C., Delaware, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maryland, Missouri, Mississippi, North Carolina, North Dakota, New Jersey, Oregon, Ohio, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and West Virginia. & Jose, S. "Woody Invaders and the Challenges They Pose to Forest Ecosystems in the Eastern United States" Journal of Forestry, Vol. But kudzu is a killer. Hickman, Jonathan E., Shiliang Wu, Loretta J. Mickey, and Manuel T. Lerdau. "Landscaping to Conserve Energy", Keung, W.M. Kudzu grow and care – vine herbaceous of the genus Pueraria also known as Pueraria montana, Kudzu perennial evergreen plant or as annual also used as ornamental plant and also for medical uses and fixing nitrogen, can grow in temperate, subtropical or mediterranean climate and growing in … [16] The Soil Erosion Service recommended the use of kudzu to help control erosion of slopes which led to the government-aided distribution of 85 million seedlings and government-funded plantings of kudzu which paid $19.75 per hectare. 49. Such a rise in potassium levels by solarization is important for soils in the Southeastern United States that tend to be highly weathered and generally have low potassium contents. Fast & Free shipping on many items! "Kudzu's invasion into Southern United States life and culture". Kudzu (Pueriaria lobata Willd.) Kudzu is a fast- ranker, which can be about 10-12 m tall / wide. Its introduction has produced devastating environmental consequences. Kudzu is a perennial invasive vine that was introduced in the United States from Asia in 1876. He is very robust and hardy to about -10 ° C, can be planted all year, if the rootstock is protected from frost by mulching greater. In China, kudzu root is used in herbal remedies, teas, and the treatment of alcohol-related problems. That shades out the trees, and everything underneath dies. [11], Other uses may include: paper products, food products, insect repellents (the smoke from burning leaves), honey, and methane production. This plant is a staple food in Japan. Once established, kudzu grows at a rate of one foot per day with mature vines as long as 100 feet. The magnificent inflorescences are about 20cm long, stand up and smell strongly of vanilla. By the early 20th century, southerners began to use kudzu for purposes other than ornamentation and so kudzu began to come closer in contact with the land which, in turn, encouraged its spread throughout the southeast. [7] Seed predation is quite prevalent, with up to 81% of seeds incurring damage in populations studied in North Carolina. Of the plants that can successfully compete with kudzu, many are other invasive species such as the Chinese privet and the Japanese honeysuckle. $66.12 $ 66. Don’t plant it. Even though it is the root of the Kudzu vine that is usually used as a medicine, the flowers and leaves of the plant have medicinal properties too. The maximum length the vine can reach is 30 m (98 feet). Vines may grow to 100 feet vertically and 50 feet laterally. [21] Kudzu is also able to allocate large portions of carbon to root growth, allowing it to acquire sufficient nutrients for rapid growth and to spread clonally. [5][7][12] In addition, the nodes of the kudzu vine have the ability to root when exposed to soil, further anchoring the vine to the ground. [23], As chemical treatments are often ineffective for long term control and mechanical removal is likewise difficult and costly for long-term control, kudzu makes a good candidate for biological pest control. The word "kudzu" comes from the Japanese word for the plant, 葛, or kuzu. This process is ongoing, so repeat yearly until the kudzu plant dies. Kudzu (Pueraria montana var. Mowing is an effective form of kudzu … Provides kudzu resources from sources with an interest in the prevention, control, or eradication of invasive species. However, one major drawback of this biological control agent is that it is highly toxic to mammals, so extreme care would have to be taken in handling this organism. Kudzu: The Invasive Plant That Took Over the Southern United States By. Control of the vine is difficult because kudzu propagates through runners, rhizomes, nodes on vines, and seeds. Kudzu's ability to grow quickly, survive in areas of low nitrogen availability, and acquire resources quickly allows it to out-compete native species. [7] A separate study also found two weevils that attacked the stems of kudzu and eight beetles that complete larval development in the kudzu roots. [6], Once established in a habitat, kudzu is able to grow very quickly. Kudzu seedling nurseries produced and distributed more than 73 million seedlings between 1935 and … [7] When evaluations of potential control agents are made, the range of the control agents must be taken into account. Kudzu is a perennial climbing vine native to eastern Asia that was recently found in Leamington, Ontario. [21] Another way to control kudzu is goats and sheep. The kudzu plant produces fragrant blossoms which you can make into jelly, syrup and candy. [11], In the United States, kudzu has been used as livestock feed, in fertilizer, and in erosion control, and the vines have been used for folk art. Apply a second dose of herbicide in late summer. [7][8][14] Kudzu was introduced to the Southeast in 1883 at the New Orleans Exposition. [7] By 1946, it was estimated that 1,200,000 hectares (3,000,000 acres) of kudzu had been planted. 4.3 out of 5 stars 580. Avoid waterlogging . Kudzu leaves, flowers, blossoms, vine tips and roots are edible. [14] The efficacy of the treatment of alcohol-related problems is currently under question, but experiments show promising results. Its introduction has produced devastating environmental consequences. Fresh seeds germinate according to experience and the young plants thrive just fine. Even though the Chinese have been using the Kudzu root for medicinal purposes as early as 200 B.C. Kudzu is a fast-growing vine native to the subtropical regions of China and Japan, as well as some other Pacific islands.1, 2 The plant consists of leaves (containing 3 broad oval leaflets), purple flowers, and curling tendril spikes.3, 4 Because the stem grows up to 20 m in length and due to its extensive root system, kudzu has been used to control soil erosion. Under the right growing conditions, it spreads easily, covering virtually everything that doesn't move out of its path. Kudzu also forms symbiotic relationships with nitrogen-fixing bacteria to convert atmospheric nitrogen (N2) into ammonium which can be used by surrounding plants. Up close, kudzu might at first be confused with a vigorous poison ivy plant. [11][14] In Japan, the kudzu root starch (or kuzu root starch) extracted from kudzu roots is used in cooking and natural medicines, and it is used to make hay that sick animals will eat. [15], Of the diseases that have been identified as potential biological control agents, the fungal pathogen Myrothecium verrucaria has been shown to be very promising. Kudzu is an invasive, destructive vine that thrives in conditions ranging from shade to bright sun. [7] When kudzu was first introduced in the southeast, it was initially used as an ornamental vine to shade homes. Kudzu is a very stress-tolerant plant. Although first-year stems typically grow only 1/2 inch in diameter, older stems may reach diameters of 4 inches. (it was usually prescribed as a medicine to combat alcoholism), only recently has it started gaining popularity in alternative herbal health.. In McNeely, J. Get it as soon as Tue, Dec 1. Our species profiles include selected highly relevant resources for the species (organized by source), and access to all species related resources included on our site. In 1953 the United States Department of Agriculture removed kudzu from a list of suggested cover plants and listed it as a weed in 1970. Originally from East Asia, kudzu was brought to the U.S. as an ornamental plant in the nineteenth century. [18] The fast growth and high competitive ability is achieved through several key features of kudzu that are detailed below. By Sandra Avant July 13, 2016 . [7][11] It has been recorded in Nova Scotia, Canada, in Columbus, Ohio, and in all five boroughs of New York City. Primary kudzu roots can weigh over 180 kg, grow to 18 cm in diameter, and penetrate soil at a rate of 3 cm in depth per day. [11], Kudzu also has potential as a source for biofuel. The plants are in the genus Pueraria, in the pea family Fabaceae, subfamily Faboideae. In Vicksburg, kudzu has invaded 190 of the 2,000 total acres of the park and threatens to diminish the historical value of the park. [9][10] Each leaflet is large and ovate with two to three lobes each and hair on the underside. He is very robust and hardy to about -10 ° C , can be planted all year , if the rootstock is protected from frost by mulching greater . Kudzu is a vine. [7] As a twining vine, kudzu uses stems or tendrils that can extend from any node on the vine to attach to and climb most surfaces. Stems can reach the diameter of ½ to 4 inches, but there are report of old ‘stumps’ nearly 12 inches across in Georgia. [citation needed], Bill Finch, "Legend of the Green Monster," Smithsonian Magazine, vol. For a long time, it was viewed as a “wonder plant”—in the 1930’s the government paid landowners in the southeastern United States eight dollars per acre to plant kudzu for erosion control and cattle grazing. In addition, the fungus does not spread outside of areas where it is applied. Kudzu kills or damages other plants by smothering them under a blanket of leaves, encompassing tree trunks, breaking branches, or even uprooting entire trees. [7] Power companies must spend about $1.5 million per year to repair damage to power lines. Soil solarization is a thermal (heat) method that utilizes solar-enhanced heating of the soil to kill the root system of the plant, thereby avoiding the use of pesticides and other more dangerous (fire-based) means to control the plant. Kudzu is an invasive plant species in the United States. For many years, it was even planted to control erosion. Disease development is very high at around 30 °C to 40 °C, which matches field conditions. Spray the herbicide onto kudzu in spring when it is most vulnerable after winter dormancy. Applying Herbicides Choose the right herbicide for your needs. [7], Kudzu management is of great concern in the management of national parks in the southeast such as Vicksburg National Military Park, Chickamauga and Chattanooga National Military Park, and Great Smoky Mountains National Park. Kudzu and other invasive weeds pose a significant threat to the biodiversity in the southeast. 104, 366-274. [7] From this survey, several leaf-feeding beetles and sawflies that have no other known hosts were identified. You obviously know that kudzu is invasive in the South. University of Ottawa; Michael Graham Richard is a … [7], While little research has been conducted on the impacts of plant invasion on atmospheric conditions, a study conducted at Stony Brook University in New York shows that kudzu has increased the concentration of atmospheric NOx in the eastern United States, which causes a 2 ppb increase in tropospheric ozone during high temperature events in addition to soil acidification, aluminum mobilization, and leaching of nitrate (NO3−) into aquatic ecosystems. [4], Kudzu is a perennial vine native to Asia, primarily subtropical and temperate regions of China, Japan, and Korea,[5][6] with trifoliate leaves composed of three leaflets. Once rooted, most stems lose connection with each other within one year, allowing each stem to become a physiologically independent individual, and requiring that all stems be treated or removed in order to eliminate a population. ©2020 Walter Reeves / The Simple Gardener, Inc. All Rights Reserved. "Herbicide Tests for Kudzu Eradication. [18], There are several methods for controlling kudzu growth that are used in the Southeastern United States. 46, no 5, September, 2015, p. 19. [5] However, chemical treatments are expensive, and killing off the plant completely requires large amounts of herbicides (40-80 gallons per acre). Every part of the kudzu plant is larger than life -- leaves, older stems, tubers and purplish flower clusters. [5][7] These attributes of kudzu made it attractive as an ornamental plant for shading porches in the southeastern United States, but they facilitated the growth of kudzu as it became a "structural parasite" of the South,[7] enveloping entire structures when untreated[11] and often referred to as "the vine that ate the South".[13]. [6] This ability allows it to flourish in nitrogen-poor sites where other plants are unable to grow. Kudzu was once considered an exotic plant, but now we think of it more as a landscaping or agricultural nuisance. Get the best deals on Kudzu Root for your home salon or home spa. All-Natural Liquid Formula for 2X Absorption - Kudzu, Milk Thistle, B Vitamins and More. [7] Kudzu is also a "structural parasite", meaning that, rather than supporting itself, it grows on top of other plants and buildings to reach light. All total, kudzu has the ability to spread up to 60 feet per growing season. The plant was first introduced to the United States in the late 1800s as an ornamental and later grown as a forage crop and soil stabilizer. On top of that the vine makes a high quality basket weaving material, the roots can be dried and powdered for export to Japan, and the biomass, my god the biomass. Miller, James H., and Ronald E. Kudzu is an invasive plant species in the United States. [7] Other pathogens have been tested as potential biological control agents, but have proven to be ineffective. This part must also be destroyed to prevent re-implantation. 3.6 out of 5 stars 121. [5][7] The roots are tuberous and are high in starch and water content, and the twining of the plant allows for less carbon concentration in the construction of woody stems and greater concentration in roots, which aids root growth. A Faster Way to Get Rid of Kudzu . The vine has a growth rate of 0.3 m (1 foot) every day. The most prominent effect of this method of control is the increase in potassium. Start by harvesting the kudzu in the field or purchasing prepackaged kudzu starch. Control Kudzu by Mowing. [17], Kudzu was intentionally introduced to North America by the Soil Erosion Service and Civilian Conservation Corps in the 1930s for the purpose of controlling soil erosion in the American Southeast. By 1997, the vine was placed on the "Federal Noxious Weed List". "Kudzu (, Forseth. Otherwise, I found seeds available on EBay. Never plant kudzu anywhere near your house. The higher level of potassium in all soils undergoing solarization demonstrates the successful release of K from decomposing kudzu plant tissues. It has been spreading rapidly in the southern U.S., "easily outpacing the use of herbicide spraying and mowing, as well increasing the costs of these controls by $6 million annually". Does not require water. [7][11] The leaves have the ability to fix atmospheric nitrogen, which can supply up to 95% of leaf nitrogen to the plant in poor soils. The vine densely climbs over other plants and trees and grows so rapidly that it smothers and kills them by heavily blocking sunlight. Kudzu is a climbing, semi-woody, perennial vine in the legume family that has the potential to reach up to 100 feet in length. The magnificent inflorescences are about 20cm long , stand up and smell strongly of vanilla . Alternately arranged leaves are compound with three broad leaflets up to 4 inches across. [18] In the southeast, the spread of kudzu is especially troublesome because of the high level of biodiversity in this region that is not found in other regions of the United States. Harrington, Timothy B., Laura T. Rader-Dixon, and John W. Taylor. ", Frye, Matthew J., Judith Hough-Goldstein, and Jiang-Hua Sun. Kudzu is believed to have originated in Japan, where the ecosystem (primarily the tendency of kudzu to experience above-ground die back over winter) kept the vine from becoming a nuisance,[14] and it is thought to have been introduced to China[11] and likely Korea. [5], Kudzu's primary method of reproduction is asexual vegetative spread (cloning) which is aided by the ability to root wherever a stem is exposed to soil. is a leguminous vine native to China. Cook the root - it contains about 10% starch which can be extracted and used as a coating in deep fried foods, or for thickening soups etc. Q: I live in Nevada and would like try growing kudzu as a indoor house plant. A small herd can reduce an acre (0.4 ha) of kudzu every day. I don’t think it would survive a Nevada winter outdoors so raising the vine indoors is your only hope. [7][8] Five species in the genus Pueraria (P. montana, P. lobata, P. edulis, P. phaseoloides and P. thomsoni) are closely related and kudzu populations in the United States seem to have ancestry from more than one of the species. [19] This claim, however, was disputed in 2015 with the United States Forest Service estimating an increase of 2,500 acres (1,000 ha) per year. Tropical kudzu is a pioneering species that smothers neighbour plants under a solid blanket of leaves. It's everywhere, and growing. Photograph by Harum Kuh via Wikimedia. The vine was widely marketed in the Southeast as an ornamental plant to be used to shade porches,[7][15] and in the first half of the 20th century, kudzu was distributed as a high-protein content cattle fodder and as a cover plant to prevent soil erosion. Browse and purchase gardening books by Walter Reeves, plus select titles by other authors. [5][7] Today, kudzu is estimated to cover 3,000,000 hectares (7,400,000 acres) of land in the southeastern United States, mostly in Alabama, Georgia, Tennessee, Florida, North Carolina, South Carolina and Mississippi. True. "Biology and Preliminary Host Range Assessment of Two Potential Kudzu Biological Control Agents. It can eventually become so heavy that it can damage the structural integrity of your home. The name is derived from the Japanese name for the plant East Asian arrowroot(Pueraria montana var. ", Adams, Nicole E., et al. 12 ($16.53/Fl Oz) Save more with Subscribe & Save. [7] In addition, it takes about $5,000 per hectare (2.5 acres) per year to control kudzu. Michael Graham Richard. [18] In the 135 years since its introduction, kudzu has spread over three million hectares (ha) of the southern United States, and continues to 'consume' the south at an estimated rate of 50,000 hectares (120,000 acres) per year, destroying power lines, buildings, and native vegetation in its path. [7], Although kudzu prefers forest regrowth and edge habitats with high sun exposure, the plant can survive in full sun or partial shade. Blaustein, R.J. (2001). At a growth rate of one foot each day, it can covered entire trees, fields, fences, and even abandoned cars and houses. Because of this, kudzu growth can be problematic for other plants too. [8], A different and less time-consuming option for the control of kudzu is treatment with herbicides. Kudzu is drought tolerant and only the above ground portions of the plant are damaged by frost. Organisms that feed on kudzu will often feed on similar non-target species that are important in agriculture, such as soybeans and hog-peanuts. They reduce the environment to impoverished "vine barrens". Estimates of the vine's spread vary, from the United States Forest Service's 2015 estimate of 2,500 acres (1,000 ha - 10 km²) per year to the Dep… According to a U.S. Department of Agriculture (USDA) study, the use of combined management programs can control kudzu more quickly than individual methods in use today.. An invasive weed, kudzu was introduced to the United States in the late 1800s. and Vallee, B.L. Kudzu is a useful fodder crop for livestock as well as an attractive ornamental. Kudzu is native to China and Japan, where it has long been grown for its edible starchy roots and for a fibre made from its stems. [7][14] In Korea, kudzu root is harvested for its starch, which is used in various foods including naengmyon, as well as a health food and herbal medicine. With a plant like kudzu you could probably greatly increase herd densities. Kudzu can quickly cover trees, even those that are 50 to 100 feet tall. November is a good time to collect seeds so if you have any friends in GA, they could go collect some for you. You are bidding on 5 piece seeds  . Farmers were paid $8.00 per acre by the Soil Erosion Service to plant kudzu, and more than 1.2 million acres were planted under this subsidized program. It will grow overtop of a pine forest, covering the canopy with a layer of vines that capture all the sunlight at the top. [11] In Korea, kudzu grows in areas where the temperature can drop to −22 °F (−30 °C). [7][22], Another form of chemical removal other than herbicides is soil solarization. Kudzu, (Pueraria montana), twining perennial vine of the pea family (Fabaceae). $6.49 $ 6. It has been spreading rapidly in the southern U.S., "easily outpacing the use of herbicide spraying and mowing, as well increasing the costs of these controls by $6 million annually". A growing instructions will be provided via email. Leftover root fragments from lawnmowers can also take root and become established. One root can produce many vines, all of which creep outward—horizontally and vertically—clinging and climbing and creating curtains of kudzu. These include mechanical, chemical, and biological methods. These methods, though more effective than herbicides, are more time-consuming. [13] Vines must be mowed down just above ground level every month or two during the growing season in order to prevent them from growing back. Kudzu (Pueraria montana [Lour.]Merr.) It is declared a noxious weed in the USA and an invasive plant in Costa Rica, Ecuador, Puerto Rico and the Pacific Islands (Hawaii, French Polynesia, Niue and New Caledonia) . Straightforward in attitude , ideal as a container plant . When using this method of kudzu control, all of the plant material must be removed and/or destroyed (burned or fed to cattle) to prevent the vines from taking root and re-growing. Now the dominant nitrogen-fixing plant in the eastern United States, kudzu fixes an estimated 235 kg of nitrogen per hectare per year, which is an order of magnitude higher than the rates of native species. There are a variety of different … [11] Kudzu is also used as a food crop in Java, Sumatra, and Malaya, and can be found in Puerto Rico and South America. A: As we say in the South “Margie, Margie, Margie….are you tetched in the head?” But we also say “Here – hold my beer while I try this!”. It will quickly climb up the sides of your house and cover it. The southern U.S. has been hit the hardest, but kudzu has been discovered as far north as Canada. Unfortunately, it quickly became a problem because of its rapid growth. Lots of fun ! [1] This has earned it the nickname "the vine that ate the South". Kudzu Kudzu takes over the side of a bridge. Some common herbicides used are picloram and triclopyr; the most effective are picloram and tebuthiuron. Of these states, three in the southeast have the heaviest infestations: Georgia, Alabama, and Mississippi.[18]. Jr., I.N. Throughout the year suitable for outdoor applications in a protected location . Kudzu has appeared larger than life because it’s most aggressive when planted along road cuts and railroad embankments—habitats that became front and center in the age of the automobile. Some gardeners try to fight kudzu takeovers by giving the invasive vine a taste of its own medicine. Kudzu grows out of control quickly, spreading through runners (stems that root at the tip when in contact with moist soil), rhizomes and by vines that root at the nodes to form new plants. “The Vine that ate the South” is no longer just a southern problem either. The translation of the German ad text says: Kudzu is a fast- ranker , which can be about 10-12 m tall / wide. [11], The kudzu plant was introduced to the United States from Japan in 1876 at the Centennial Exposition in Philadelphia. Do you know where I can purchase seeds? Kudzu (Pueraria lobata) is an invasive vine that was introduced to the U.S. from Japan and distributed throughout the South for erosion control. [7] The climate and environment of the Southeastern United States allowed the kudzu to grow virtually unchecked. [7] Along the vines are nodes, points at which stems or tendrils can propagate to increase support and attach to structures. [15] There are several biological means that are already in place and more that may be implemented to control the growth of kudzu. Its ability to reproduce and spread quickly allows it to quickly cover shrubs, trees, and forests, where it blocks the sun's rays from the plants below it, decreasing or completely eliminating their photosynthetic productivity. Boil the leaves and blossoms or peel the roots, as needed. In Japan, kudzu thrives in mountainous regions, ranging from the 44th parallel north (the island of Hokkaido) to the 30th parallel north (the island of Kuchinoshima) and many of the lowlands and the islands. ; Jenkins, M. A. l… In addition, the weight of the vines can actually cause the trees to uproot. In the absence of other plants, nitrogen then builds up in the soil, allowing the maintenance of large leaf areas and high photosynthetic rates. One case study saw a significant decrease in the growth of kudzu after just two years, whereas another study required the use of the herbicide for up to ten years. [7] The roots can account for up to 40% of total plant biomass. Then in the cold winters, the vines will freeze and the hillside will be a … ", Marshall, Jessica "Kudzu Gets Kudos as a Potential Biofuel". [8] Herbicides are found to be most effective when they are used during the typical growing season, June–October, and when used for successive years. Raising from seed is easy and available all year round for beginners. "Effects of Kudzu (, Chickamauga and Chattanooga National Military Park, Environmental issues in the United States, "Kudzu's invasion into Southern United States life and culture", "Controlling Kudzu With Naturally Occurring Fungus", "Fungus Tapped to Take on Kudzu : USDA ARS", Kudzu Gets Kudos as a Potential Biofuel, 2008, https://en.wikipedia.org/w/index.php?title=Kudzu_in_the_United_States&oldid=991870494, Invasive plant species in the United States, Articles with dead external links from February 2020, Articles with permanently dead external links, Articles with unsourced statements from June 2013, Creative Commons Attribution-ShareAlike License, This page was last edited on 2 December 2020, at 06:27. Relax and stay calm with eBay.com. Kudzu spreads over the landscape and creates a thick carpet that smothers neighboring plants and trees, … [7], In addition to its abilities to obtain nutrients and spread quickly, kudzu leaves have paraheliotropic movements, meaning that they move in response to the movement of the sun in order to maximize photosynthetic productivity. 2006. [21], Most mechanical means of kudzu removal practiced in the southeastern United States involve mowing the vine or cutting it back. Potential control agents have to be rejected if they are shown in laboratory and field tests to feed on these non-target plants. lobata [Willd] Maesen & S. Almeida) is a large, trifoliate-leaved, semi-woody, trailing or climbing perennial vine in the Fabaceae (legume or pea) family. "Kudzu Root: An Ancient Chinese Source of Modern Antidipsotrophic Agents. [13] Another method of mechanical removal is to remove the crown of the plant. Kudzu is often viewed as a pest plant with its long-reaching vines. and Innis, Anne F."Kudzu (, Black, R.J. and Meerow, A.W. [2] Estimates of the vine's spread vary, from the United States Forest Service's 2015 estimate of 2,500 acres (1,000 ha - 10 km²) per year[3] to the Department of Agriculture's estimate of as much as 150,000 acres (61,000 ha - 610 km²) annually. [7], Currently, grazing by goats and pigs is the best method for control of the vine. The purple flowers are fragrant and appear in 25 cm long, erect clusters. A. Webster, C.R. [11] The starch is used in Japanese cuisine, and is widely consumed as such in that country. While kudzu may seem as Southern as Georgia peaches or Florida oranges, this invasive vine was actually introduced to the United States. This has earned it the nickname "the vine that ate the South". [7], The economic impact of kudzu in the United States is estimated at $100 million to $500 million lost per year in forest productivity. Outsidepride Purple Hyacinth Bean Red Leaved Plant Vine Seed - 100 Seeds. They are followed by flat, hairy seeds that divide when they are mature. is the most well-known invasive plant in the southeastern United States. [23] Soil solarization affects the micronutrients and macronutrients in the soil. It was cultivated by Civilian Conservation Corps workers as a solution for the erosion during the Dust Bowl. Kudzu is a group of climbing, coiling, and trailing perennial vines native to much of East Asia, Southeast Asia, and some Pacific islands, but invasive in many parts of the world, primarily North America. Kudzu can also root wherever stems make contact with soil, allowing vines to grow in all directions. Bacterial blights, insect herbivory, and insect seed predation occur in high levels in field populations of kudzu.
