Rocky openings; apparently endemic to Isle Royale.
Packera insulae-regalis is newly described fertile hexaploid, probably derived from hybridization between tetraploid P. paupercula and octoploid P. indecora. The flowering stems are quite similar to those of P. paupercula so the vegetative rosettes are the best way to easily separate P. insulae-regalis from P. paupercula. See Kowal, Judziewicz, & Edwards (2011) for additional information.
