This common introduced garden plant escapes successfully into the wild appearing most often in places where you suspect people have tipped garden rubbish. There must be another method of dispersal other than fly-tipping however for I have seen this perennial flourishing on the central reservation of a dual carriageway where dumping is just a touch difficult.

It has escaped into the wild all over England, much of Wales and southern Scotland and is dotte about in Ireland.
