Invasive of the Month:
English Ivy
Christian Snead
Join us each month in this new series as we learn about different invasive species!
English ivy (Hedera helix L.) is a Category I invasive species in the state of Georgia, meaning that it poses a serious threat to native habitat. English ivy is an evergreen perennial climbing vine that attaches to tree bark, brickwork, and other surfaces by excreting a glue-like substance that helps it stick and stay in place.
It is native to Europe, Scandinavia, and Russia, having first been introduced to the United States in 1727. It continues to be sold as an ornamental plant despite its threat to natural ecosystems, parks, landscapes and other green areas. You can find English ivy in 28 different states, including Hawaii.
English ivy thrives in shady to full-sun conditions, and prefers moist soil. It doesn’t tolerate drought or salinity well. The vines grow outwards, ranging in length from anywhere between 3 to 50 feet, dependent on how tall its supporting structure is.
