A. novi-belgii is naturalised on hedge banks, railway banks, roadsides, rubbish tips and waste ground. In addition, it sometimes occurs on river banks, lakesides and in fen vegetation. Lowland.
A. novi-belgii was introduced as a garden plant in 1710. It was recorded in the wild by 1860 and the extant population at Wicken Fen (Cambs.) was found in 1864. Stace (1997) and other authors suggest that it has been much over-recorded in the past for A. x salignus and, no doubt, also for A. x versicolor.
Native of eastern N. America; widely naturalised in N.W. & C. Europe.
