Canadanthus
Introduction '''''Canadanthus''''' is a North American monotypic genus of flowering plants in the family Asteraceae. The only species is '''''Canadanthus modestus''''' (formerly ''Aster modestus''), commonly known as '''great northern aster''' or '''western bog aster'''. It is native to most of Canada (Alberta, British Columbia, Manitoba, New Brunswick, Ontario, Saskatchewan, Quebec, and Yukon) and to northern parts of the United States (Alaska, Idaho, Michigan, Minnesota, Montana, North Dakota, Oregon, and Washington).
Description ''Canadanthus modestus'' is an herbaceous perennial spreading by means of underground rhizomes, thus producing large colonies. It has several flower heads, each with pink or purple ray florets and white or yellow disc florets.
