Roadside Invasives

This field guide identifies common and showy roadside invasive grasses and forbs, all of which are on various State noxious weed lists. Several of the plants are native to the US, but are not native to specific geographic areas in which they are known to be invasive. These plants can invade and degrade both agricultural land and natural areas. Invasive plant species are common to many regions of the United States and continue to adapt and move to new habitats, particularly disturbed roadside areas. Many of these plants are also common garden species. For additional information go to:
