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 species is occasionally used as an ornamental grass, as well as in prairie and meadow plantings. It spreads readily by seed, and can survive along roadsides; escapes have led it to establish east and north of its native range. We mark new populations expanded because they are mostly close to the native range.
