Schedonorus arundinaceus (formerly Festuca arundinacea) · Cool-season, Perennial, C3 grass, highly adaptable to the transition zone
AI-generated identification · may be incorrect
Grass Category
Lawn/Turf Grass / Pasture Grass / Often considered an invasive/weed grass in fine manicured lawns
Hardiness Zones
USDA Hardiness Zones 4 to 9, excellent heat and drought tolerance for a cool-season grass, performs exceptionally well in the transition zone
Grass Family
Poaceae, subfamily Pooideae, tribe Poeae
Variety / Cultivar
Wild-type / Forage type or coarse clump-forming pasture type
About This Grass
Forms coarse, upright, light to medium green clumps that stand out prominently against finer-textured turfgrasses like Kentucky Bluegrass or Bermuda. Reaches up to 2-4 feet tall if unmowed, but maintained at 2-3 inches in lawns. Texture is coarse with prominent veins.
Blade Characteristics
Coarse width (>4mm), flat shape, pointed tip, light to medium green color, rolled in the bud (vernation), prominent parallel veins/ridges on the upper surface, membranous ligule, and small or absent auricles
Root System
Deep, extensive fibrous root system going down 2-3 feet or more, moderate to fast establishment speed, low thatch tendency, excellent drought avoidance due to deep roots
Growing Information
Origin Region
Native to Europe; widely cultivated and naturalized across North America, particularly in the transition zone and temperate regions
Growth Habit
Bunch-type (clump-forming) with short, underground rhizomes that can form a somewhat coarse, loose turf over time
Sunlight & Water Needs
Requires full sun to partial shade; moderate watering needs once established but highly drought tolerant due to deep roots; adapts well to a wide range of soil types with a preferred pH of 5.5 to 6.5
Mowing & Maintenance
Ideal mowing height of 2.5 to 4 inches, mowed weekly during peak growth, moderate fertilization (2-4 lbs N per 1000 sq ft per year), infrequent dethatching needed, low to medium maintenance level
Special Characteristics
Good traffic and wear tolerance, high resistance to major turf diseases, moderate salt tolerance, good shade tolerance compared to other cool-season grasses, excellent drought recovery, poor winter color retention in colder zones
Ecological Information
Introduced species widely used for erosion control, pasture forage, and turf; provides moderate wildlife habitat value; can become a coarse weed clump in fine residential lawns where it disrupts uniform turf appearance
