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.

Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

This relatively small grass spreads readily by burs that stick to clothing or animal fur; it favors sandy or gravelly sites, and has taken advantage of anthropogenic habitats including roads and railways to spread into new areas. We mark a few of the more distant northerly populations introduced because they are separated from the rest of its range by large distances. We may update this if we see evidence that this species is spreading to fill in gaps in its range.
