Among the listed grasses, which is the perennial lawn species suited to warm-zone conditions?

• A. Bermuda grass
• B. St. Augustine grass
• C. Kentucky bluegrass
• D. Turf-type tall fescue

Answer: (D)

Perennial lawn grasses keep coming back year after year, so in warm-zone climates you want one that can persist through heat and stress. Turf-type tall fescue fits this role because, among the options, it offers durable performance with a deeper root system that helps it handle heat and drought better than many other cool-season grasses. This combination—year-after-year persistence plus improved heat tolerance—makes it well suited to warmer conditions compared with the cooler, less heat-tolerant bluegrass varieties. While warm-season grasses like Bermuda and St. Augustine perform very well in hot weather, the question focuses on a perennial option that remains vigorous in warmer climates, and tall fescue provides that among the listed choices.
