The light-violet flowers of this pretty fall aster attract a range of native bees and butterflies. It is a host plant for the Wavy-Lined Emerald moth and the Asteroid moth. Of the five plant communities most prevalent in eastern Washtenaw County prior to 1800 (Dry Southern Forest, Dry-Mesic Southern Forest, Mesic Southern Forest, Oak Barrens, and Southern Hardwood Swamp), this aster is associated with the one most approaching a prairie, the Oak Barrens community.
