There is little evidence of significant change in the distribution of this species in Ireland. Naturalised plants have been reported in Britain, but S. bermudiana has been confused with S. montanum and records need to be checked (Stace, 1997), so any changes in its alien distribution cannot be easily assessed.
Oceanic Wide-temperate element; in Europe restricted to Ireland as a native but widespread in N. America.
