Most towns, cities, and other municipalities have weed ordinances (local law) concerning what is a weed, what is not defined as a weed in their jurisdiction, and what is allowed to be grown on the property of local citizens. How do you know if you are really in violation, or if your “flowers” just remind others of weeds?
