Mary Augusta Hiester Reid was an American-born Canadian painter and teacher. She was best known as a painter of floral still lifes, some of them called "devastatingly expressive" by a contemporary author, and by 1890 she was thought to be the most important flower painter in Canada. She also painted domesticated landscapes, night scenes, and, less frequently, studio interiors and figure studies. Her work as a painter is related in a broad sense to Tonalism and Aestheticism or "art for art's sake".
