Kentucky Bluegrass is a perennial, cool season, sod forming grass that spreads by underground runners called rhizomes.   Native to Europe and Asia and naturalized in North America, it is widely adapted throughout the cool humid and transitional zones and can be effectively utilized in arid zones with supplemental irrigation. Due to its wide adaptability and exceptional turf quality it is the most widely used cool-season grass.

Bluegrass varieties are unique in that they exhibit a wide range of genetic diversity.  Such diversity is an advantage for disease and insect resistance and improved turf quality when bluegrasses are used in a blend such as Royal Blue Platinum.  There are well over 100 varieties of Kentucky Bluegrasses with various traits and characteristics.  The varieties chosen for this blend have been tested, highly rated, exhibit exceptional overall turf quality,  and disease and drought resistance when compared to other bluegrasses.  It meets our platinum standards of superiority for variety quality and seed purity.  Learn More.
