Tall Fescue
Schedonorus arundinaceus (formerly Festuca arundinacea) · Cool-season perennial, C3 grass, highly well-adapted to the transition zone
AI-generated identification · may be incorrect
Grass Category
Lawn/Turf Grass, Pasture/Forage Grass, Erosion Control
Hardiness Zones
USDA Hardiness Zones 4 through 9. Excellent heat and drought tolerance for a cool-season grass, making it a staple in the transition zone. Goes semi-dormant during severe summer heat or prolonged drought.
Grass Family
Poaceae, subfamily Pooideae, tribe Poeae
Variety / Cultivar
'Kentucky 31' (KY-31), a widely used older cultivar known for exceptional toughness and wide adaptability
About This Grass
Forms a somewhat coarse, upright turf with a bunching tendency. Height can reach 2 to 4 feet if unmowed, but maintained at 2 to 3 inches in lawns. Color is medium to dark green with good wear tolerance. Textures range from medium-coarse in older forage types to medium-fine in modern turf types.
Blade Characteristics
Blades are medium-coarse (4-8mm wide), flat, with pointed tips and prominent parallel veins on the upper surface. Vernation is rolled in the bud. Ligule is a very short membranous band, auricles are blunt and rounded, and the collar is broad and continuous.
Root System
Deep fibrous root system going down 2 to 3 feet or more, which grants superior drought and heat tolerance compared to many other cool-season grasses. Moderate establishment speed from seed, and forms a moderately dense sod over time.
Growing Information
Origin Region
Native to Europe, widely naturalized and cultivated across North America, particularly in the transition zone and upper South
Growth Habit
Primarily a bunch-type grass (clump-forming), though modern turf-type varieties can exhibit short, weak rhizomes allowing for limited lateral spread
Sunlight & Water Needs
Thrives in full sun to partial shade (more shade tolerant than Kentucky bluegrass or perennial ryegrass). Requires moderate watering once established, with high drought tolerance due to its deep root system. Prefers well-drained loamy soils with a pH of 5.5 to 6.5.
Mowing & Maintenance
Ideal mowing height is 2.5 to 4 inches. Mow frequently during peak spring and fall growth periods. Fertilization needs are moderate (2 to 4 lbs N per 1000 sq ft per year). Low to medium maintenance level overall.
Special Characteristics
Exceptional wear and traffic tolerance, good disease resistance (though susceptible to brown patch in hot, humid weather), moderate salt tolerance, and strong erosion control capabilities due to its deep root system.
Ecological Information
Introduced species widely used for pasture, turf, and erosion control. Provides good wildlife cover and forage for livestock (though older varieties like KY-31 often host an endophyte fungus that deters insects and herbivores). Non-invasive in managed turf, but can establish in native prairies if left unmanaged.
