Which of the following are examples of cool-season grasses?

Cool-season grasses thrive in the northern climates where temperatures are moderate and are most active during the cooler months of spring and fall. Kentucky bluegrass and tall fescue are prime examples of cool-season grasses.

Kentucky bluegrass is highly favored in cool, moist climates for its lush appearance and ability to provide a dense turf, making it a popular choice for lawns and recreational areas. It has a growth peak in the spring and fall when temperatures are more favorable.

Tall fescue, on the other hand, is known for its adaptability and tolerance to heat and drought due to its deep root system. It remains green and resilient during the summer months, but still benefits from the cooler growing conditions of spring and fall, aligning it with the characteristics of cool-season grasses.

The other choices contain grasses that are primarily warm-season varieties, which are adapted to thrive in warmer climates and show peak growth during summer.
