Which turfgrass has folded vernation, tapered leaf tip, and leaf blades that have a dull underside?

• A. Fine-leaf fescue
• B. Annual bluegrass
• C. Bermudagrass
• D. Zoysiagrass

Answer: (A)

Focusing on leaf morphology helps you identify turfgrasses: vernation shows how the leaf is folded in the bud, leaf tip shape indicates blade taper, and the blade underside texture tells you about the surface finish. A fine-leaf fescue is characterized by folded vernation, a pointed, tapered leaf tip, and a dull underside on the leaf blades. These traits come together to distinguish it from other common turfgrasses.

Annual bluegrass typically has a boat-shaped leaf tip rather than a sharply tapered one, and its blade underside isn’t described as particularly dull. Bermudagrass and zoysiagrass usually show rolled vernation and broader blades with a glossier underside, so they don’t match the combination of folded vernation, tapered tip, and dull underside as well as fine-leaf fescue does.
