Forms dense stands on disturbed soil. Regarded in restoration and landscaping as a useful volunteer cover crop. Not invasive, but may exclude native colonizers of disturbed soil. A prolific producer of very persistent seed. It has developed herbicide resistance at a few Alberta sites. [1] Other aliens with similar hab­its include Tansy Mustard (Descurania sophia), Blue-bur (Lap­pula squarrosa), and Lamb’s Quarters (Chenopodium album).

Edible: but likely an acquired taste. Used in very small amounts it can add an interesting flavor.
