In warmer regions of the United States, which grass is commonly grown as a perennial lawn?

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

Answer: (C)

In warmer regions, the grass chosen for a perennial lawn hinges on how well it can handle heat and keep a dense, green appearance through hot summers. Turf-type tall fescue is a cool-season grass that, with modern breeding, offers improved heat tolerance and drought resistance, so it can form a durable, long-lasting lawn in many warm areas. Its deep root system helps it withstand summer stress, and newer cultivars provide good texture and uniform density, making it a reliable perennial choice across a range of warm climates. While other warm-season grasses like Bermuda and St. Augustine perform well in heat, tall fescue’s ability to stay green in milder winters and maintain quality under heat in transitional zones makes it a common perennial option in warmer regions. Kentucky bluegrass, by contrast, is less suited to hot conditions, tending to lose quality when temperatures rise.
