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 showy, this species is not frequently cultivated in gardens. It thrives in disturbed anthropogenic habitats, including roadsides, railroads, and waste areas, but it is mostly limited to sites with sandy soils. We mark the entire new range as expanded even though eastern populations are spotty and locally isolated, because it is mostly spreading on its own.
