This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.

This sedge is widely cultivated, including as a lawn replacement. It is also salt-tolerant, and thrives along roads in wet areas where road salt inhibits the growth of other vegetation, such as in highway medians. As a result it has established east of its native range, but only in the northern states, most abundant around Chicago. We mark the new range expanded because it is largely contiguous with the native range, relatively connected with only short gaps in most places.
