Description: This native species is very similar to Persicaria maculosa (redshank or persicaria) but it has pale green flowers and it lacks the red coloration of the stem. It grows in similar situations to P. maculosa, and often mixed with it. It is rather less common than that species.

Polygonum lapathifolium is an alternative name.
