This large-leafed plant popped up recently in my yard. What is it and should I get rid of it? Thank you.

Hi - This is garlic mustard (Alliaria petiolata), a very invasive non-native plant that alters soil chemistry and outcompetes native plants. It spreads very effectively by seeds and the seeds can remain viable in the soil for ~5-10 years. If you have had these plants in your area for awhile, it may take several years to get them under control because of the seed bank in the soil.


Pull out all that you see, or, for a large area, cut them down with a string trimmer prior to seed development and dispose of the plants in the trash. Limiting seed dispersal is key. On our website you will find details about garlic mustard and how to manage it, https://extension.umd.edu/hgic/topics/garlic-mustard.

Thanks. I don’t recall seeing it before in my garden which is why it caught my attention. I will dispose of it as you have suggested.
