|New England Aster|
Symphyotrichum novae-angliae (L.) G L Nesom. (formerly Aster novae-angliae L.), commonly known as the New England Aster 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.
The plant grows up to 120 cm (47 inches) with a stout, hairy stem and clasping, lance-shaped leaves with entire margins. The flower heads are showy with yellow disc florets at the center and ray florets that range from a deep purple or rose to rarely white.
This species inhabits a wide variety of habitats and soil types, though it does not tolerate strong shade.
Owing to its attractive flowers, numerous cultivars have been developed. Moreover, as a result of its increased horticultural popularity, it has been introduced to many areas beyond its natural range, including Europe and several western US states.
Over 70 cultivars of Symphyotrichum novae-angliae have been raised, although only about 50 survive in commerce today. There is less diversity of habit and flower than in novi-belgii, whose cultivars are often derived from hybrids. The novae-angliae cultivars grow to between 90 and 180 cm in height, with the notable exception of 'Purple Dome', at <60 cm.
