What is the most invasive plant in Tennessee?

Tennessee’s Battle with Kudzu: The Vine that Ate the South

In the lush landscapes of Tennessee, a silent invader is claiming territory at an alarming rate. Known colloquially as “the vine that ate the South,” kudzu (Pueraria montana var. lobata) has been identified as the most invasive plant species in the state. This fast-growing vine, originally from Asia, was introduced to the United States in the late 19th century for ornamental purposes and soil erosion control. However, its aggressive nature soon turned it into an ecological menace.

Understanding the Kudzu Invasion

Kudzu’s ability to grow rapidly—up to a foot per day during peak growing season—allows it to smother other vegetation, including trees, by blocking sunlight. Its resilience and adaptability make it difficult to eradicate once established. The Tennessee Department of Agriculture and local conservation groups are continuously working on control methods, which include herbicides, grazing by livestock, and manual removal.

Impact on Local Ecosystems

The invasion of kudzu in Tennessee threatens native species and disrupts local ecosystems. It chokes out native plants, which are crucial for wildlife habitat and biodiversity. The economic impact is also significant, as it can damage forestry by killing young trees and can become a nuisance for farmers.


Q: How did kudzu come to Tennessee?
A: Kudzu was introduced for ornamental purposes and to combat soil erosion but quickly spread out of control.

Q: Why is kudzu so hard to control?
A: Its rapid growth rate, extensive root system, and ability to regenerate from root and vine fragments make it a formidable opponent.

Q: What is being done to manage kudzu in Tennessee?
A: Management efforts include the use of herbicides, controlled grazing, and manual removal, though these methods require persistence and ongoing maintenance.


Invasive Species: A non-native organism that causes ecological or economic harm in a new environment where it is not naturally found.

Ecological Menace: A factor, such as an invasive species, that poses a serious threat to the balance of an ecosystem.

Biodiversity: The variety of life in a particular habitat or ecosystem, including the number of different species present.
