Which turfgrass species has a bunch-type growth habit?

• A. Kentucky Bluegrass
• B. Zoysia Grass
• C. Perennial Ryegrass
• D. Bentgrass

Answer: (C)

Growth habit describes how a grass spreads and fills space. A bunch-type grass forms clumps and doesn’t spread widely across the soil surface, so patches stay tufted unless the sod is very dense or overseeded. Perennial ryegrass is a cool-season species that grows in tight tufts, lacking extensive stolons or rhizomes, which is why it is classified as bunch-type. This contrasts with Kentucky bluegrass, which spreads via underground rhizomes to form a continuous turf; Zoysia and creeping bentgrass spread by stolons or rhizomes to knit the lawn together. Knowing this helps explain mowing and coverage needs—bunch-type grasses can show gaps between clumps and may require more frequent mowing or strategic overseeding to maintain a smooth, even turf.
