Aster lanceolatus
Ecology
A. lanceolatus has become established along railways and river banks, on roadsides and by car parks and on waste ground and tips. Lowland.
Status
Trends
A. lanceolatus has been cultivated since 1811 and was recorded from the wild by 1865. According to Stace (1997) it is second only to A. x salignus in frequency in Britain, yet several county Floras record it as rare. This may indicate regional variation, but is more likely to reflect the difficulties experienced in separating A. lanceolatus from A. x salignus. Most occurrences have arisen from garden outcasts, but it may have been accidentally introduced by N. American servicemen in Wiltshire (Oliver, 1998).
World Distribution
Native of eastern N. America; widely naturalised in W. & C. Europe.
