Native or Not Present

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.


Found in part sun and moist conditions, including in open woodlands and moist meadows in floodplains, margins of fresh water, including both standing and running water. Tolerates a wide range of soil types but requires ample moisture. Tolerates temporary flooding but needs soil that occasionally dries out.

Life Cycle

This species is a long-lived perennial that often forms large colonies through long underground rhizomes. Typically reproduces more vegetatively than by seed.

Flowers in fall, with a typical timing relative to other Symphyotrichum species. Seeds are wind-dispersed.


This plant is rarely used as a gardening or landscaping plant, because of its aggressive nature.

It is used in riparian buffers and ecological restoration projects, as it competes favorably against invasive plants and its aggressive root system is good at holding soil.
