Description: Kentucky Bluegrass is a cool-season grass species that is one of the most widely planted lawn grasses in northern, cooler regions. It spreads laterally by rhizomes, has dark color, and fine leaf texture. It can tolerate lower mowing heights than tall or fine fescue and is often used in mixtures with fescues and even ryegrasses to add diversity and recuperative potential due to its spreading growth habit. The seed of Kentucky Bluegrass is significantly smaller than tall fescue, fine fescue, and ryegrass and as such it has a much lower seeding rate due to the fact that there are more seeds per pound of Kentucky Bluegrass than other species.
