exhibit much thinner leaf blades, and tolerate lower mowing heights than the tall fescues. They may be somewhat more resistant to common diseases. Otherwise, their characteristics are similar. Fine fescues are generally used in mixtures with other grasses. Bermuda grass Bermuda grass is quite commonly used for golf courses and sports fields across the southern portions of the United States. It tolerates a range of climates in the U.S., from hot and humid lagoons, inlets, and bays of the Gulf Coast, to the arid expanses of terrain like plains and deserts in the Southwest and parts of the Lower Midwest. Established bermuda grass is a network of shoots, rhizomes, stolons, and crown tissue together that usually form a dense plant canopy. This dense plant canopy can be used to propagate clonal varieties by sod, sprigs, or plugs. The aggressive and resilient nature of Bermuda grass makes it not only an excellent turfgrass but also a challenging and invasive weed in land cultivated for other purposes. Its one noted weakness is its relatively low tolerance of shade. Given the economic importance of Bermuda grass (as a sod product, agricultural forage, and, at times, as an invasive weed), it has been the subject of numerous studies. Celebration Bermuda grass: Celebration Bermuda grass is a dark–green, fine–textured, aggressive, traffic–tolerant cultivar with high recuperative potential and drought tolerance." The cultivar is a breed of Cynodon dactylon from Australia developed by turfgrass breeder Rod Riley. The grass has a distinctive deep blue–green color which makes it popular on golf courses and for private home lawns throughout the southern United States. As a leading cultivar, the research on the grass is extensive. The grass was rated for the best shade tolerance by the United States Golf Association. A researcher at the University of Florida noted this cultivar's, "good wear tolerance, quality, and color ratings" in the Central Florida environment. The grass was the overall best–performing turfgrass in a 2–year drought resistance study commissioned by the San Antonio Water System and performed by Texas A & M extension service. The cultivar was also the top–rated Bermuda grass for drought resistance in a test conducted in South Carolina. Along with many golf courses across the southern United States, the Tampa Bay Buccaneers elected to install Celebration Bermudagrass in their stadium. Discovery Bermuda grass: Discovery is a Bermuda grass that has an exceptional dark blue-green color. It also has
