Anticosti Island aster is a perennial wildflower native to eastern Canada and Maine that spreads by rhizomes and grows on gravelly, calcareous river and lake shores. It is a wild species rather than a common garden plant, so it suits native or naturalistic plantings on well-drained, lime-rich gravel.
