Ravenna Grass (Saccharum ravennae)
Class B Noxious Weed in Benton County
Ravenna Grass was added to the State Weed List January of 2015. Ravenna Grass is a very tall bunch grass that was sold as an ornamental grass in local nurseries, and used in landscape settings throughout this area.
Ravenna grass is easily recognized by its reddish stems, white mid-vein and pale inflorescence, reaching a height of 6 to 12 feet. It out competes native plants and will invade outside of original planting areas, quickly spreading to neighboring property.
If you currently have ravenna grass the most effective control method is to dig the entire plant out, making sure to get the root ball out. If this can't be done right away, remove any seed heads by cutting, bagging and disposing of them. Do not compost or discard in outlying areas. Seedlings will be abundant for several years after the original plants have been removed and will need to be controlled. Use herbicides when the plant is green and actively growing. Always use herbicides according to the label.
