Tall Eggers' nutrush plant in swamp environment

Eggers' Nutrush

Eggers' nutrush (Scleria eggersiana) is a perennial sedge that can be found in aquatic and emergent habitats. It has typically been found in Cypress domes and strand swamps. It is easily spread through large rhizomes beneath the ground and by its small seeds. This species can be identified by its triangular stem and fused leaf tips. Eggers' nutrush has been observed and verified in the Okaloacoochee Slough in Hendry and northeastern Collier counties in Florida as well as in Palm Beach County. This species is part of the Early Detection Rapid Response program. If you see this plant in the wild, please report it immediately.

What can you do to help protect Florida waters and lands?

Report Eggers' nutrush sightings! Call the FWC Invasive Plant Management office at 1-850-617-9430 

Do not plant or transport Eggers nutrush.

Clean, drain, and dry all gear completely before entering another water body. It is easier and much cheaper to prevent an invasive plant than it is to manage after it becomes established. Check shoes and clothing as the seeds and fruit are small enough to be easily transferred to a new location. 

Report Immediately
