|Persicaria orientalis is the plant in question and it is propagated only by seed. The seed requires cold treatment before it will germinate so store collected seed in an unheated building overwinter or refrigerate for 12 weeks before sowing. This plant readily self sows and the small seedlings transplant easily. Perhaps you can find some small seedlings beneath a mature plant? Hope so!
