Goutweed is a common weed that often grows in gardens and is difficult to control. Synonyms for goutweed include ground elder, bishop's weed, and herb gerard. Ground elder, also known as Aegopodium podagraria, is a perennial weed that spreads rapidly through the roots and can be challenging to eradicate. Bishop's weed, or ammi majus, is another name for this invasive species. It is commonly confused with parsley and can be found growing in the wild, as well as in gardens. Herb gerard, or Geum urbanum, is a plant that is used for medicinal purposes and is sometimes called spotted avens or clove root.
