Mixed Lawn (predominantly Tall Fescue and Kentucky Bluegrass)
Festuca arundinacea and Poa pratensis · Cool-season perennial, C3 pathway
Grass Family
Poaceae, subfamily Pooideae
Grass Category
Lawn/Turf Grass
Variety / Cultivar
Likely a Turf-Type Tall Fescue (TTTF) blend with Kentucky Bluegrass
Hardiness Zones
USDA Zones 4-7; excellent cold tolerance and moderate heat tolerance for the Transition Zone.
About This Grass
A heterogeneous lawn appearance with medium to dark green color. Visible patches show differing textures: clumps of coarser, wider blades (Fescue) interspersed with finer, denser patches (Bluegrass).
Blade Characteristics
Fescue: 3-5mm width, visible longitudinal ribs, pointed tips, rolled vernation. Bluegrass: 2-3mm width, smooth surface, boat-shaped tips, folded vernation. Ligules are short/membranous.
Root System
Fescue provides deep fibrous roots (up to 2-3 feet) for drought resistance; Bluegrass provides a shallow rhizomatous network for filling in bare spots and sod stability.
Growing Information
Origin Region
Europe and North Africa; widely adapted to the Transition Zone and Northern US
Growth Habit
Mixed: Bunch-type (Fescue) and Rhizomatous (Bluegrass) producing a dense sod
Sunlight & Water Needs
Full sun to partial shade (4-6 hours minimum). Moderate watering; Fescue component provides high drought tolerance while Bluegrass requires more consistent moisture.
Mowing & Maintenance
Ideal height 3.0-4.0 inches. Medium maintenance; requires 2-4 lbs Nitrogen/1000 sq ft annually. Aeration recommended in fall.
Special Characteristics
High wear tolerance and excellent shade tolerance (from Fescue). The mix allows for better disease resistance and 'self-repairing' ability via Bluegrass rhizomes.
Ecological Information
Introduced species used for stabilization. Provides moderate nesting cover for insects. Often mixed with Clover (visible in image) which fixes nitrogen in the soil.
