Perilla frutescens from Asia is widely cultivated as an ornamental or as an oilseed crop. Up to present it has been recorded in Italy in Lombardia and Veneto, always as a casual alien (Celesti-Grapow et al., 2009a). It is here reported for the first time from Piemonte. In addition to the locality cited above, it was also seen in Arquata Scrivia along river Scrivia. It does not seem to naturalize (yet).
