Which turfgrass does not have rhizomes?

• A. Kentucky bluegrass
• B. Creeping bentgrass
• C. Bermudagrass
• D. Zoysiagrass

Answer: (B)

Spread through rhizomes means the grass uses underground horizontal stems to push out new shoots and roots, helping it cover more ground from below the surface. Among common turfgrasses, Kentucky bluegrass, Bermudagrass, and Zoysiagrass all rely on these underground rhizomes to expand and recover after damage, creating a dense, connected network. Creeping bentgrass, however, mainly expands via above-ground runners called stolons that grow along the surface and root at the nodes. Because its spread is through stolons rather than underground rhizomes, creeping bentgrass does not have rhizomes.
