Discussion
Variety drummondii is often confused with Symphyotrichum urophyllum, a usually white-rayed species with erect array branches. Hybridization has been reported with S. urophyllum, as well as with S. shortii or S. undulatum (the name Aster ×finkii Rydberg possibly applies to such hybrids).
Selected References
None.
