Which turfgrass is known for rolled vernation and a multi-ribbed leaf topside?

• A. Turf-type Tall Fescue
• B. Creeping Bentgrass
• C. Zoysiagrass
• D. Centipedegrass

Answer: (A)

Leaf morphology is a strong clue in telling tall fescue apart from other common turfgrasses. Rolled vernation means the leaf blade develops rolled up, rather than unfolding flat, which is a characteristic often seen in tall fescue. The topside of its leaves shows multiple prominent veins, giving a clearly ribbed, multi-ribbed appearance. This combination—rolled leaf development and a distinctly ribbed blade surface—helps identify turf-type tall fescue more than the other options, which tend to have flatter, smoother leaves with different venation patterns.
