Aster ontarionis of Michigan Flora.

Forested river banks and floodplains; moist thickets and forests, whether oak-hickory or beech-maple, rarely in other forest types or open areas (presumably at the edges of forests).

Looking very much like a hairier S. lateriflorum, this species, however, is colonial from long-creeping rhizomes. Plants with the leaves glabrate have been called var. glabratum (Semple) Brouillet & Bouchard.
