Which turfgrass has a distinguishable midrib and rolled vernation?

• A. Creeping Bentgrass
• B. Bermudagrass
• C. Zoysiagrass
• D. Tall Fescue

Answer: (A)

Leaf structure is a key clue in distinguishing turfgrasses. Creeping bentgrass has very fine, slender leaves with a clearly visible central vein, or midrib, that you can notice on the blade. It also exhibits rolled vernation, meaning the leaf is formed inside the bud rolled rather than unfolded flat. This combination—a distinct midrib plus rolled vernation—is characteristic of creeping bentgrass and helps set it apart from the other options, which tend to have broader leaves or different leaf-formation patterns. So the option that best matches these leaf traits is creeping bentgrass.
