Aronia prunifolia (Marshall) Rehder. Purple Chokeberry. Phen: Apr-May; Sep-Oct. Hab: Balds, bogs, seepages, swamp forests. Dist: NL and ON south to NC, KY, IN, and IL.

Origin/Endemic status: Native

Taxonomy Comments: While apparently originating as a hybrid between our other two species, A. prunifolia exists in populations independent of the two parent species, apparently reproducing successfully. It seems best to treat a now independent lineage such as this as a separate taxon. Some plants, though, may merely represent F1 hybrids occurring with both parents.
