Kudzu is a beautiful ornamental climbing plant originating from southern China and Japan. Kudzu is also the only plant among these 10 notorious invaders. In 1876, kudzu appeared for the first time in the exhibition hall of the Centennial Memorial Museum in Philadelphia, USA. At the time it was touted as a "tough, fast-growing" ground cover that could help locals curb soil erosion problems. Kudzu was officially introduced to the United States for this purpose.

More than 50 years later, it is precisely because of these two advantages that kudzu has received two new nicknames. The first is "the climbing plant that eats the south" and the second is "the green danger." Nowadays, kudzu is spreading wildly in the southern states of the United States, becoming a disaster, and even has the tendency to continue to move north, with its northernmost tentacles extending to New Jersey. Kudzu has almost no natural predators on American soil, and their presence has caused serious ecological disasters in southern states. The question Americans are thinking about is no longer utilizing it, but how to eradicate it.
