Final answer:
Zoysiagrass is the turfgrass with folded vernation, boat-shaped leaf tips, and a very short ligule, making it distinguishable from others like Tall fescue, Centipedegrass, and Bermuda grass.
Step-by-step explanation:
The turfgrass has folded vernation, boat-shaped leaf tips, and a very short ligule is b) Zoysiagrass.
Characteristics such as folded vernation indicates how the new leaf blades emerge and fold, which in the case of Zoysiagrass is a prominent feature. Boat-shaped leaf tips refer to the shape of the leaf blade, where the ends of leaves resemble the prow of a boat.
This is another notable characteristic of Zoysiagrass. The ligule is a small outgrowth at the junction of the leaf blade and leaf sheath, and Zoysiagrass has a particularly short one compared to other species of turfgrass. These identifying features help distinguish different types of turfgrasses from each other, aiding in their selection for use in various landscaping projects based on the climate and maintenance considerations.
