Plants are very variable particularly in indumentum and leaf size and shape. Considered by some authorities to be introduced, but the early dates of two collections (1803 by Caley, 1804 by Brown) would suggest that it is most likely indigenous. At least some populations in Victoria such as in Melbourne are most probably not indigenous. The type subspecies is almost cosmopolitan but does not occur in Australia.
