Which turfgrass has rolled vernation and a multi-ribbed leaf topside?

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

Answer: (A)

Leaf emergence pattern and leaf surface texture are being used to identify turfgrasses. Rolled vernation means the blade forms a tight tube as it unfurls, rather than starting flat. A leaf topside with multiple visible ribs means the surface has several raised longitudinal ridges. Turf-type tall fescue shows both traits, with blades that emerge rolled and have a distinctly multi-ribbed topside. This combination helps separate it from the other options: creeping bentgrass has ultra-fine, smooth blades with less pronounced ribbing; zoysiagrass blades are broader and flatter with fewer prominent ribs; centipedegrass has a softer texture and smoother blade surface without strong ribbing.
