There are nine searchable categories in the Weed Identificaiton Database. They are AQUATIC, GRASSES, LANDSCAPE, PASTURE, SEDGES, SPINY, and WOODY. The idea is to help you narrow your search. Weeds are not included in more than one category. For example, horsenettle is a PASTURE weed but it is found in the smaller category of SPINY plants.
