Bromus inermis Leyss.
Smooth brome is a cool season exotic that is especially troublesome in disturbed portions of old pastures in the tall grass and mixed prairie regions. In its native range smooth brome grows on roadsides, river banks, edges of fields and woods and pastures. Smooth brome was first recognized as a potential forage grass in Europe because of its drought resistance. Smooth brome has been widely planted as a forage and cover crop. It is highly persistent. It forms a dense sod that often appears to exclude other species, thus contributing to the reduction of species diversity in natural areas.
A scientific consensus for the distribution of smooth brome in Indiana has been agreed upon. Smooth brome can be found in all 92 counties in Indiana.
