    Life History


    UK Status

    A. officinalis has declined throughout most of its British range, due to drainage and development in the coastal zone. Much of the loss occurred before 1930, but it has continued since then, particularly in East Anglia.

    VC55 Status

    Rare in Leicestershire and Rutland. It was not recorded in the 1979 Flora survey of Leicestershire.
