Greeting Erica!

Thank you for submitting your report to the Oregon Invasives Species Hotline. I greatly appreciate you taking the time to submit your photos.

I reviewed your photos and they appear to be Common or Lesser Burdock (Arctium minus). This is a relatively common weed in our area, but one that rarely gets too prolific.

The burs of this plant can cause a problem, especially if you have livestock or pets, as they readily stick to fur, and cause discomfort for your animals. As such, I recommend removal.

Based on the relatively small number of plants you have present, I would recommend simply digging up the plant, and disposing of it as trash. The burdock plants will have a long tap root, so you will want to be careful to remove the entire root to prevent it from resprouting.

remember to be careful around the burs, they will catch on clothing and fabric easily. So avoid wearing your favorite sweater, while digging these plants.

Please feel free to contact me if you have any additional questions. Good luck in all your efforts.
