Like most Southern children, I accepted, almost as a matter of faith, that kudzu grew a mile a minute and that its spread was unstoppable. I had no reason to doubt declarations that kudzu covered millions of acres, or that its rampant growth could consume a large American city each year. I believed, as many still do, that kudzu had eaten much of the South and would soon sink its teeth into the rest of the nation.

I’m not sure when I first began to doubt. Perhaps it was while I watched horses and cows mowing fields of kudzu down to brown stubs. As a botanist and horticulturist, I couldn’t help but wonder why people thought kudzu was a unique threat when so many other vines grow just as fast in the warm, wet climate of the South. I found it odd that kudzu had become a global symbol for the dangers of invasive species, yet somehow rarely posed a serious threat to the rich Southern landscapes I was trying to protect as a conservationist.

Now that scientists at last are attaching real numbers to the threat of kudzu, it’s becoming clear that most of what people think about kudzu is wrong. Its growth is not “sinister,” as Willie Morris, the influential editor of Harper’s Magazine, described in his many stories and memoirs about life in Yazoo City, Mississippi. The more I investigate, the more I recognize that kudzu’s place in the popular imagination reveals as much about the power of American mythmaking, and the distorted way we see the natural world, as it does about the vine’s threat to the countryside.
