Sawgrass is a sedge, not a grass. It was this plant that Marjory Stoneman Douglas referred to in her seminal work: "The Everglades: River of Grass." A second species (C. mariscoides) occurs in a limited area in north Florida.  Its uses and culture are similar. Typically used in wetland restoration. Also useful for planting in brackish settings where an emergent aquatic is desired. Spreads rapidly to cover large areas.
