There are approximately ten known populations and as many as twenty additional historical locations. These populations are widely scattered throughout the entire state. This plant may be impacted by invasive wetland species. Only one population has over a thousand stems, with typical populations having a few hundred stems. Most of the Long Island historical locations are considered extirpated.
There are about 10 populations that have been seen in recent years. Exact trends at these populations is unknown. Most of these populations are not large but appear healthy. There is no reason to suspect that they are declining but there is no data to prove this assertion. Therefore, short term trends are unknown but are suspected of being stable.
At least four populations that occurred in the New York City area are believed extirpated. There are at least 20 additional populations that have not been seen in recent years. One of these populations was searched for without success but may still be extant. It is unknown if the other historical populations are still extant. Overall, long term trends are not clear but indicate at least some decline.
