Symphyotrichum novae-angliae (L.) G L Nesom. (formerly Aster novae-angliae L.), commonly known as the New England aster, hairy Michaelmas-daisy or Michaelmas daisy, is a flowering herbaceous perennial plant in the Asteraceae family. It is native to almost every area in North America east of the Rocky Mountains, but excluding the far north of Canada as well as some of the southern United States. Symphyotrichum novae-angliae was introduced to Europe in 1710; a common garden escape, it has naturalized along roadsides and on disturbed ground.
