This introduction from Madeira does have something of the appearance of Herb Robert about it but is considerably larger with prominent and more beautiful flowers.

G. rubescens has escaped in only a few places on the mainland in the south of England and east Anglia otherwise it is found only in The Isle of Man, The Isles of Scilly and The Channel Islands. It is not found in Scotland, Wales or Ireland. Having reported the official position it had escaped very succesfully in at least one place here in Cheshire in 2007 and 2008.
