Which type of turfgrass is known to tolerate shady, cool areas but struggles in hot, sunny areas?

Fine (red) fescue is known for its exceptional ability to thrive in shady, cool areas, making it a popular choice for lawns under trees or in other environments where sunlight is limited. This turfgrass species has a fine texture and is often used for its aesthetic appeal and adaptability in low-light conditions. However, it is less suited to hot, sunny areas, as these conditions can cause stress and lead to poor growth or even death.

In contrast, Kentucky bluegrass generally prefers full sun and can struggle in continuous shade, while improved turf-type tall fescue and ryegrass are better adapted to a wider range of environmental conditions, including both sun and shade. These characteristics distinctly set fine (red) fescue apart as the ideal choice for shaded, but not sunny, environments.
