Trumpet creeper or trumpet vine is an aggressive woody perennial vine that can find it’s way into pastures, hayfields, open woods, and is most commonly seen growing on telephone poles on roadsides. If touched, it can cause a rash or irritate the skin, therefore earning the nickname- Cow Itch Vine.

Leaves on trumpet creeper are compound- meaning several join one stem, are coarsely toothed, and have a long point. Stems have aerial rootlets that help it climb fences, telephone poles, trees, etc as much as 70 ft tall. Trumpet creeper has reddish-orange, tubed-shaped flowers. The flowers are great for hummingbirds but the plant is best suited where it can’t overtake other plants or production goals.

Because it is a perennial, trumpet creeper control needs to be focused on the root system. Regardless of what control option you choose, you will need to be diligent in making sure all roots are removed and continue to scout for regrowth. A mechanical control option would be digging up the roots. If you’re interested in a chemical control, spot spraying with glyphosate is an option for small populations of trumpet creeper. A systemic herbicide for woody or brushy plants would need to be used since trumpet creeper has a tough woody stem. Be sure to read the label of any product you choose to use. Making sure it is labeled to control the plants you are looking to target and reading all safety measures and precautions are important!
