Did you know?
This is a widespread, variable species occurring in much of the United States (except the Southeast) and in Europe and Asia. It was first collected in New York by George W. Clinton of the Buffalo herbarium on a visit to Staten Island in 1874.

State Ranking Justification [-]
There are nine existing populations but phragmites may be crowding out plants in some locations. There are 14 historical occurrences, mostly from the early 1900s, and most of these probably did not persist.
