Riviera Bermudagrass is a new generation cold-tolerant turf-type seeded Bermudagrass produced and marketed exclusively by Johnston Seed Company in Enid, Oklahoma. Riviera is a revolutionary product developed by the Oklahoma State University Turfgrass Development Team, with financial support from the United States Golf Association. It is the result of many years of selection for improved turf quality, cold tolerance, seed production, and disease resistance in the transition zone.

The transition zone offers a unique weather pattern with periods of extreme cold, extreme heat, and drought. Bermudagrasses produced in the Southwestern United States typically suffer from severe winter injury and cool-season grasses produced in the Northwestern United States struggle with the summer's heat, drought, and disease pressure.
