Tall Fescue
Schedonorus arundinaceus (formerly Festuca arundinacea) · Cool-season, Perennial, C3 grass; highly suitable for the transition zone
AI-generated identification · may be incorrect
Grass Category
Lawn/Turf Grass, Pasture/Forage Grass, and Erosion Control Grass
Hardiness Zones
USDA Hardiness Zones 4 through 9, highly favored in the transition zone where other cool-season grasses struggle with summer heat.
Grass Family
Poaceae, subfamily Pooideae, tribe Poeae
Variety / Cultivar
Kentucky 31 (KY-31), a classic older forage and utility turf variety known for extreme toughness and adaptability
About This Grass
Tall Fescue forms a coarse to medium-textured, upright tussocky growth. Unmowed, it can reach heights of 2 to 4 feet with upright flowering stems and narrow, spike-like panicles. Color is a rich medium-to-dark green which it retains well through moderate heat and drought stresses.
Blade Characteristics
Blades are medium-coarse (4-8mm wide), flat with prominent parallel veins on the upper surface, and a shiny underside. Tips are sharply pointed. Vernation is rolled in the bud. The ligule is a short membranous fringe, and auricles are absent or blunt.
Root System
Deep, extensive fibrous root system extending down 2 to 3 feet or more, contributing to exceptional drought avoidance and tolerance compared to many other cool-season grasses. Establishes relatively quickly from seed.
Growing Information
Origin Region
Native to Europe, widely naturalized and cultivated across North America, particularly in the United States transition zone and humid temperate regions
Growth Habit
Bunch-type grass that can form a moderately dense sward over time via short rhizomes under ideal management, though primarily clump-forming
Sunlight & Water Needs
Performs best in full sun but exhibits better shade tolerance than warm-season grasses. Requires moderate water once established, relying on deep roots for dry periods, though it goes into summer dormancy if severely dry.
Mowing & Maintenance
Mow at 2.5 to 4 inches for lawns to encourage deep rooting and shade out weeds. Fertilization needs are moderate (2-4 lbs N per 1000 sq ft annually). Low to medium maintenance overall.
Special Characteristics
Exceptional heat and drought tolerance for a cool-season grass, good wear tolerance, deep root system, fair shade tolerance, and strong disease resistance compared to Kentucky bluegrass.
Ecological Information
Introduced species widely used for pasture, forage, turf, and erosion control on slopes. Often infected with an endophytic fungus that provides insect resistance but can affect livestock grazing unless using endophyte-free varieties.
