VRiv, HSF, HNF. Also naturalised NSW, Tas. Indigenous in Europe eastwards to Siberia, also northern Africa and central Asia to Japan. Naturalised in New Zealand, Canada, USA. Noted along stream-banks near Cann River and the Strathbogie Ranges where planted to a limited extent for erosion control, poorly collected but apparently rare in Victoria.
Vegetative reproduction is limited; abundant seed is set in some locations and populations are expected to expand.
Salix ×sordida A. Kern., a hybrid between S. purpurea and S. cinerea, is widespread in Europe (Meikle 1984) and could be expected in Victoria.
