Notes

Flowers September to October

Wetland Indicator: NA

I photographed some of these plants in early October and the petals were looking a bit spent. Quite an unusual aster, which might explain why some authors refer to this species as Oclemena acuminata (Michx.) Greene. Possibly extirpated from OH.
