Which turfgrass has rolled vernation, a distinguishable midrib, and a somewhat long ligule?

• A. Creeping Bentgrass
• B. Turf-type Tall Fescue
• C. Bermudagrass
• D. Kentucky bluegrass

Answer: (A)

Leaf features used to identify turfgrasses include how the leaf blade folds (vernation), whether a prominent central vein (midrib) is visible, and how long the ligule is. Creeping bentgrass has leaves that are rolled in vernation, a clearly visible midrib along the blade, and a relatively long ligule. This combination creates a distinctive, diagnostic look that matches the description in the question, making it the best fit among common turf species. The other grasses typically don’t show all three traits together in the same way—different vernation patterns, shorter ligules, or less conspicuous midribs—so they don’t align with the described characteristics as well.
