Summary

Kentucky bluegrass (Poa pratensis L.) is a widely used turfgrass in many temperate-climate areas of the United States and the world. It is an adaptable, long-lived perennial that forms a medium-textured, dark green turf with appealing leaf density and aggressive sodforming rhizomes. Kentucky bluegrass is also included in pasture mixes. However, its low midseason forage yield, aggressiveness in mixtures, and high nitrogen requirements limit its use as a forage grass.
