Detail

Botanical Name: Phragmites australis (Cav.) Trin. ex Steud. ssp. australis
Common Name: Common Reed
Synonym(s)
Flora of Virginia Name/Status: Phragmites australis (Cav.) Trin. ex Steud. ssp. australis
Comments: The map contains all records for the species in Virginia, where it predominately occurs as a highly invasive, non-native entity, ssp. australis. Recent studies, however, have shown that a native genotype exists as well (ssp. americanus Saltonstall, Peterson & Soreng), though very infrequent. Although further field and herbarium work is needed, the map above is undoubtedly an accurate representation of the distribution of ssp. australis, the overwhelmingly predominant genotype in our area.
Habitat: Freshwater and oligohaline (rarely mesohaline) tidal marshes, disturbed tidal
shores, salt scrub, interdune swales, dredge-spoil deposits, ditches, and other wet, disturbed habitats. Common in the estuarine zones of the Coastal Plain; frequent elsewhere in the Coastal Plain; infrequent (though sometimes locally abundant) in the Piedmont and mountains.
Native Status: Introduced
