Introduced

This map is based on our research. We have checked its accuracy to Level 3 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

Some sources report this species as introduced in New York State but this is from a record that NY Plant Atlas marks as not naturalized and not persisting. The records from Vancouver, and the Gotter Prairie near Scholle, OR, however, are of naturalized plants.
