Johnsongrass (Sorghum halepense) is a summer perennial grass native to the Mediterranean region. It was introduced to the Southern United States in the early 1800s as a perennial forage crop and is still in use for cattle grazing in many states. After introduction, it escaped cultivation and is now present or naturalized in nearly every state in the continental United States. It is recognized as invasive or as a noxious weed throughout the south, southwest, and west and is one of the ten most troublesome weeds in the world. In California johnsongrass is classified as a “C” list noxious weed.
