Common names: Italian ryegrass
Festuca perennis (Italian ryegrass) is an annual or biennial grass (family Poaceae) found throughout California except in the Great Basin and deserts. Italian ryegrass prefers areas with fertile, well-drained soils, including roadsides, fields, orchards and vineyards. Italian ryegrass is commonly cultivated for erosion control, pasture forage, and turf, but has escaped cultivation in many areas. Italian ryegrass is currently very widespread.Cal-IPC Rating: Moderate
