    Life History


    UK Status

    Widespread and fairly frequent as an established plant in the wild in Britain.  This is probably the commonest Michaelmas-daisy in Britain, but together with Aster lanceolatum (syn = Symphyotrichum) it is probably under-recorded; many specimens are wrongly identified as Aster novi-belgii. 

    VC55 Status

    Uncommon or under recorded as a plant in the wild in Leicestershire and Rutland. It was not recorded in the 1979 Flora survey of Leicestershire.

    In the current checklist (Jeeves 2011) it is listed as Alien; neophyte; rarely recorded; first record form Glenfield in 1997
