Description: An attractive herbaceous perennial alien species with deep red flowers, grown as a garden ornamental but with a few colonies outside gardens, presumably derived from discarded garden rubbish containing fragments of the plant. Some at least of these 'wild' colonies seem well established (one near Whitehead railway station has been there for at least 23 years), but the plant is nowhere naturalised in Northern Ireland.

A native of the Himalayas.

An alternative name is Polygonum amplexicaule.

All names: Persicaria amplexicaulis (D.Don) Ronse Decraene; Polygonum amplexicaulis D.Don; Polygonum amplexicaule D.Don
