Riviera Bermuda Grass is a synthetic variety developed from three parental plants and released by the Oklahoma Agricultural Experiment Station with an exclusive license to Johnson Seed Company, Enid, OK.. Riviera produces a moderately fine-textured, medium dark green turf with excellent turf quality. It has adequate resistance or tolerance to the major pests of bermudagrass, particularly in the U.S. transition zone. It is sufficiently cold-hardy to be used in parts of the U. S. transition zone between warm-season and cool-season turf grasses with minimal risk. Size and color of seed may vary from image shown.
