Which turfgrass has folded vernation?

• A. Bermudagrass
• B. Zoysiagrass
• C. St. Augustinegrass
• D. Centipedegrass

Answer: (B)

Vernation describes how a new leaf blade unfurls from the sheath. When vernation is folded, the leaf blade unfurls from a folded state along a central crease rather than being tightly rolled. Zoysiagrass exhibits folded vernation, so its young leaves open with that crease, which is a useful identifying feature. You can observe this by inspecting the base of a newly developing leaf—look for a distinct fold line along the blade as it unfolds. Other common turfgrasses in the list don’t show this folded pattern, making folded vernation a helpful clue that points to zoysiagrass.
