What are Noxious Weeds? Most simple stated, a weed is a plant out of place. It is the name that umans have placed on "undesirable" lants that interfere with our land management objectives. A plant may be a weed in one place but an acceptable plant in another (example: St. Johnswort and Purple Loosestrife). Noxious weeds are weeds that, by law, must be controlled. They are usually the most invasive and aggressive of the weeds. They usually spread easily, reproduce quickly and in large quantities, and reduce populations of desirable plants. The federal and state departments of agriculture decide which plants to list as noxious.
