General Landscape Uses:
Primarily recommended for natural landscapes and habitat restorations.
Ecological Restoration Notes:
Utilized as a water and substrate stabilizer in tidal swamp restorations in South Florida. Natural populations are very rare.
Grown by one or two native plant nurseries in South Florida.
Medium herbaceous grass.
Emergent 1-2 feet above the water. Spreading from underground stems (rhizomes) and forming patches much broader than tall.
Widespread along the eastern coastline of North American west to Texas and south to Miami-Dade County and the Monroe County mainland; northeastern coast of South America. Very rare in South Florida. Perhaps never naturally present or natural populations extirpated in Broward County; now cultivated there. Reported in error for the Monroe County Keys.

Wet, inundated brackish or saline soils.
High; requires rich organic soils for optimal growth.
Salt Water Tolerance:
High; tolerates flooding by salt water.
Salt Wind Tolerance:
Moderate; grows near salt water, but is protected from direct salt spray by other vegetation.
Low; requires moist to wet soils and is intolerant of long periods of drought.
Wildlife and Ecology:
Larval host plant for Aaron's skipper (Poanes aaroni).
Can be grown from division, and by seed with difficulty.
Imperiled and sporadic in South Florida, perhaps due to widespread modifications to coastal hydrology
