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

Fine (red) fescue is recognized for its adaptability to shady and cool environments, making it an excellent choice for lawns or areas where sunlight is limited. This type of grass thrives under the canopy of trees or in regions where other grass types might struggle due to insufficient light. While it performs well in cooler temperatures and shaded conditions, fine fescue tends to have challenges in hot, sunny areas, where it may not establish as robustly as other grass types. Its fine textures and dense growth habit help it outcompete weeds in shady environments, but the heat and full sun can lead to stress and a decline in health. Thus, fine fescue is particularly suited for cooler, less illuminated regions of a lawn compared to the other types of turfgrass, which may have different tolerances and requirements.
