Discussion

Several cultivars of var. novi-belgii are sold in the horticultural trade. The following forms are not recognized here, as they represent mere color variants: forma novi-belgii, forma albiflorus (Victorin) J. Rousseau, and forma roseus E. L. Rand & Redfield.

Symphyotrichum ×subgeminatum (Fernald) G. L. Nesom (as species) (syn.: Aster subgeminatus Fernald) is the hybrid of var. novi-belgii with S. ciliolatum; it has been observed in western Newfoundland and the Gaspé (Quebec). Variety novi-belgii also hybridizes with S. anticostense (L. Brouillet and J. Labrecque 1987).
