"A weed is simply a plant out of place." By this definition, any plant could be a weed if it grows in a location where it is not wanted.  

Plants frequently classified as weeds can tolerate a wide range of environmental growing conditions making them more likely to establish themselves in the garden. Weedy species often propagate themselves easily by seed, runners, stolons or other vegetative means. 

Few plants are always considered to be weeds in all settings, but some species more often grow where we don't want them than others.

We do not cover all possible weeds, just the most common and troublesome ones in Minnesota. Some weeds are classified as invasive and should be reported to the appropriate authorities when found.
