This taxon belongs to a group which is the subject of recent taxonomic revisions. As defined in New York, this variety has been found on cliffs, ledges, and rocky slopes on or near mountain summits. Of the two known sites, one has acidic bedrock and the other appears to have some calcareous influence. The populations occur from 1250 to 2600 feet; despite its name, this taxon is not a member of the true alpine flora (New York Natural Heritage Program 2011). Calcareous rocks, ledges and cliffs along rivers (FNA 2006). Plants mostly of rivershores (Haines and Vining 1998).
This species is most easily identified when in flower.
This taxon starts to flower in early August and continues through mid-September depending on altitude. Since it is easiest to see this species when it is in full flower the best time to survey for this species is from August through mid-September, surveying lower elevations first.
