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 widely cultivated in gardens, but is also fairly weedy and aggressive, and readily colonizes anthropogenic habitats in urban and rural areas alike, including roadsides, railroads, fallow fields, and waste areas. A combination of garden introductions and spreading on its own into new habitats has led this plant to hugely expand its range east and northeast, and expand somewhat northwest as well. We mark all of this new range expanded because it is largely connected and contiguous with the native range.
