Aster anticostense, also known as Symphyotrichum anticostense or Anticosti Island aster, is a perennial member of the Sunflower family. It grows in small clumps with each stem reaching 1-2.5 feet tall. It can be distinguished from other similar looking Aster species by its long, skinny leaves and flowering head, and its unique habitat. Aster anticostense is only found on gravelly beaches of rivers and lakes with calcareous (basic) soil. It flowers from late July through September. (Labrecque and Brouillet, 1990; New England Wildflower Society, 2017; USDA and NRCS, 2017). Aster anticostense is of conservation concern because it is only found in a handful of locations in the Northeastern North America. It is listed as Threatened in Canada and as Endangered in Maine, the only US state in which it occurs. (NatureServe, 2017; USDA and NRCS, 2017).
