Bermuda grass (Cynodon spp.)
Bermuda grass is an aggressive, warm-season turfgrass species that spreads rapidly by above-ground (stolons) and below-ground (rhizomes) stems. It is the best-adapted turfgrass for full-sun areas in Oklahoma due to its excellent heat and drought tolerance during the summer and its sufficient winter hardiness.
Turf-grasses for Shaded or Irrigated Sites
Occasionally, cool-season turfgrass species are the best selection for a lawngrass. The warm-season turfgrasses can not tolerate shaded sites, so a cool-season turfgrass such as tall fescue (Festuca arundinacea), Kentucky bluegrass (Poa pratensis), or perennial ryograss (Lolium perenne) should be seeded (ideally in the fall) if a permanent turf is desired.
Cool-season grasses provide a green cover the entire year if properly watered and fertilized.Cool-season turfgrasses, such as tall fescue and Kentucky bluegrass can also be successfully grown in full sun, but requires more frequent watering during the summer than bermudagrass to prevent wilting, thinning, and a loss of turf density. Thus, cool-season turfgrasses may be utilized in full sun only when a convenient means of irrigation is available.
