The Garlic Mustard Challenge in New England is a collaborative effort to restore and protect natural ecosystems and prevent the further spread of the invasive plant garlic mustard (Allaria petiolata). The goal is to encourage people to get out on the land and care for local natural areas in New England in a fun and engaging way.


Due to the COVID19 quarantine, please LOOK FOR populations of garlic mustard in your neighborhoods or along roads. Nature Groupie does not recommend doing any stewardship or invasive plant work on conservation lands during the COVID19 quarantine. Stay local and pull only on your own land. Report SIGHTINGS of garlic mustard you observe in your neighborhood to pull later. Take a photo and submit using the form below!

  • When? Late April through early June, or whenever garlic mustard is in flower (but seeds are not yet set)
  • Where? Look for garlic mustard in your yard or neighborhood throughout New England.
  • Who? Anyone can participate! In 2020, we are LOOKING for new populations that can be pulled in future years.
  • How? Report your sightings of garlic mustard below. If you pull any garlic mustard on your own land (using social distancing!), you can report your # of bags below.
