Description

Jamaica swamp sawgrass is a native herbaceous perennial in the sedge family (Cyperaceae) that grows in boggy type soils from coastal VA south to FL and west to TX including NC. Its native habitat is brackish and fresh-tidal river marshes, upper edges of salt marshes, interdune swales and marshes. This famous sedge dominates many square miles in the Everglades in FL. The Genus name is from the Greek kladion meaning “a small branch”. The species' name is from Ancient Greek marískos, meaning “bog rush”.

This large sedge in flower can reach 8-9 feet tall and prefers full sun to partial shade in fertile wet soils to standing water. Propagation is by division of rhizomes and seed.

The large v-shaped leaves are up to 5 feet long with scabrous edges capable of cutting skin and fabric. The branching inflorescence can be 1-2 feet long and occurs in July with fruiting in October. 

This is a good plant for naturalized coastal areas in both brackish and freshwater to help control erosion. It is used in wetland restoration projects. Do not plant in areas where foot traffic will occur due to the sharp edges of the leaves.
