This is a South American introduction that was found as an escape in the south of the country but is now known from more northern counties. It is a garden escape but this one was nowhere near any garden. It is most often found near the seaside.

Tristagma uniflorum has escaped mostly into the southern English counties. The highest concentration of records is from around the London area, along the south coast of England and the east Anglian coast. Otherwise it is dotted here and there with records becoming scarcer as you go north. It is common on the Channel Islands but absent from Scotland and very rare in Ireland.
