I asked about this plant with curling, ribbon-like leaves last May, but it was too immature for an ID. You did think it might be an Aster, and it is.
The flowers appeared in late October/ early November. Maybe the photos of the flowers can help ID the kind of Aster it is?
Growing in suburban Charleston, dappled shade.
Thanks,
Virginia
Hi Virginia,
your plant best matches Symphyotrichum racemosum, a newer name for Aster racemosus, the Small white aster. It is considered to be common and is native.
