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.

We marked this species as Expanded in the western portion of its range, where it is not native, because it is a weedy species that seems to spread on its own. The northern portion of its range expansion is more contiguous with its range, whereas in the south, it is found in more isolated pockets, but the overall pattern is one of expansion.

Description & Identification

Unlike some Erigeron sp., the leaves do not clasp the base, and leaves tend to be sparser.

Prefers full sun, mesic to dry conditions, and high pH soil containing clay and/or gravel. Often found on sites that have experienced some recent disturbance. It can occur temporarily in richer, loamy soil, following disturbance, whereas it persists longer on harsher sites.
