Garlic Mustard (Alliaria petiolata) on May 8, 2008

Submitter has sample

Description of specimen

Along the path in several spots were clusters of garlic mustard in their second year bloom. We have been fighting garlic mustard on our property in NW Portland so we are very familiar with the flower clusters.


Dear Sharon,

Thank you for reporting garlic mustard! This is a high priority species in the Portland area. I will forward your report to the East Multnomah SWCD and the local cooperative weed management area. If you would like more information about efforts to control garlic mustard, and learn how you can get involved, you can contact East Multnomah SWCD at

Thanks again for reporting! Keep up the good work!
