This map is based on our research. We have checked its accuracy to Level 3 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

↑Habitat

Prefers sandy, open sites.

Found in drier woodlands, especially pine and mixed pine/deciduous forests, exposed slopes, and forests that have burned recently.

Humans temporarily created more habitat for this plant by clearing forests in New England and the Mid-atlantic; in these areas, it has declined as forest cover has regrown, as it cannot survive in rich forests with a closed canopy. This plant has probably also been harmed by fire suppression and development.

↑Uses

Uncommonly cultivated as a garden plant; valued for being smaller and less aggressive than Ageratina altissima.

Closely related to the much more common Ageratina altissima, with which it largely overlaps in range, and can hybridize. A. altissima prefers richer sites, is more shade tolerant, and has benefitted more from humans.

Numerous other species of the Eupatoriae tribe also occur.
