Kentucky Bluegrass - Poa pratensis L.

Kentucky Bluegrass is a long-lived perennial, sod-forming grass used primarily for lawns. Its leaves are soft, green to dark-green creating an attractive sod with good traffic tolerance.  It grows best in cool, humid climates however it should only be seeded into warm soil.  Late spring and summer plantings are advisable.  It prefers open sunlight, but it grows in lightly shaded situations if soil moisture and nutrients are favourable.  Although it does go dormant in dry weather, it will survive severe drought and has very good cold tolerance.  It does well in irrigated areas, but lacks tolerance to acidity and salinity.  Kentucky Bluegrass is slower to establish than most other turf grasses.
