Which of the following lists correctly names three cool-season turfgrass species and one warm-season species commonly used for athletic fields in temperate climates?

• A. Cool-season: Bermudagrass, zoysiagrass, centipedegrass; Warm-season: Kentucky bluegrass
• B. Cool-season: Kentucky bluegrass, perennial ryegrass, fine fescue; Bermudagrass
• C. Cool-season: Tall fescue, creeping red fescue, orchardgrass; St. Augustinegrass
• D. Cool-season: Kentucky bluegrass, creeping bentgrass, quackgrass; Zoysia

Answer: (B)

This item tests your ability to identify which grasses are cool-season versus warm-season and which warm-season grass is commonly used on athletic fields in temperate climates.

Kentucky bluegrass, perennial ryegrass, and fine fescue are classic cool-season turfgrasses. They perform well in cooler months, establish dense, wear-tolerant turf, and stay green through spring and fall in temperate areas. Bermudagrass is a warm-season grass that thrives in warm weather and is widely used on athletic fields in warmer parts of the temperate zone or transition zones because of its vigorous growth and quick recovery from use. So listing those three cool-season species with bermudagrass as the warm-season option matches typical field-turf practice in temperate climates. Other choices mix grasses that aren’t standard cool-season field turfs or pair a cool-season trio with a less typical warm-season for athletic fields, making them less correct for this specific combination.
