Tall Fescue
Festuca arundinacea (syn. Schedonorus arundinaceus) · Cool-season, Perennial, C3 grass
Grass Family
Poaceae, subfamily Pooideae, tribe Poeae
Grass Category
Lawn/Turf Grass
Variety / Cultivar
Turf-Type Tall Fescue (TTTF); variety unknown but exhibiting the narrower leaf characteristics and darker green color typical of modern cultivars like 'Rebel IV' or 'Titan Ltd.'
Hardiness Zones
USDA Hardiness Zones 4-7; highly successful in the transition zone because of its heat tolerance compared to other cool-season grasses.
About This Grass
A dense, upright grass with a medium-to-coarse texture. In the image, the grass is a deep emerald green with frayed leaf tips indicating recent mowing with a dull blade. It forms a thick canopy that remains green throughout the year in moderate climates but may show heat stress in peak summer.
Blade Characteristics
Blade width is medium (3-4mm); shape is flat with prominent longitudinal veins/ridges on the upper surface. Tip is distinctly pointed (unlike the boat-tip of bluegrass). Vernation is rolled in the bud. The leaf margins are rough/scabrous to the touch. Ligule is short and membranous; auricles are small and blunt or absent.
Root System
Deep fibrous root system (often reaching 2-3 feet deep), providing excellent stability. Minimal thatch tendency; establishment speed is moderate (faster than bluegrass, slower than ryegrass). Weak sod-forming ability compared to rhizomatous grasses.
Growing Information
Origin Region
Europe and North Africa; widely naturalized across North America, particularly in the Transition Zone.
Growth Habit
Bunch-type (clump-forming); lacks significant rhizomes or stolons, though modern turf-type varieties may exhibit very short, limited rhizomatous activity for improved density.
Sunlight & Water Needs
Prefers full sun but has excellent shade tolerance for a cool-season grass. Requires moderate water (1 inch per week). Possesses high drought tolerance due to deep roots but will go dormant in extreme heat.
Mowing & Maintenance
Ideal mowing height is 3.0 to 4.0 inches. Higher cuts promote deeper roots. Requires 2-4 lbs of Nitrogen per 1000 sq ft per year. Low-to-medium maintenance; does not require frequent dethatching but needs periodic aeration and overseeding to repair bare spots.
Special Characteristics
Excellent wear tolerance and traffic durability. High resistance to summer patch and dollar spot, though susceptible to Brown Patch in high humidity. Good salt tolerance and moderate shade tolerance. Frayed ends in image suggest a need for blade sharpening.
Ecological Information
Introduced species in North America. Used extensively for soil stabilization and erosion control on slopes. Provides cover for small mammals; often used in blends with Kentucky Bluegrass (90/10 ratio) to provide diversity and disease resistance.
