It grows up to 6 feet tall and has small pink or white flowers that bloom from June to September.

  • Pull Them Out By Hand : If you only have a few vines, pull them out by hand before they blossom & set seeds, making sure you get all the roots too
  • Cut Them Back Regularly :If caught early enough, cutting back the vine regularly will prevent it from producing seeds and eventually weaken it over time.
