About Cladium mariscus (L.) Pohl
Cladium mariscus (L.) Pohl is a species of flowering plant in the sedge family. Its common names include swamp sawgrass, great fen-sedge, saw-sedge, and sawtooth sedge, and it was previously called elk sedge. This species is native to temperate Europe and Asia, where it grows in base-rich boggy areas and along lakesides. It can reach up to 2.5 metres (8 ft 2 in) in height, and its leaves have hard, serrated edges. In the past, Cladium mariscus was an important material used for building thatched roofs. Harvesting the plant was an arduous task, because its sharp edges can cause deep lacerations.
