As usual for Persicaria, the stems are in short 'joined' sections, and green going reddish. The leaves are linear to narrow-elliptic - greater than 5 times longer than wide. Inflorescences on forwardly-directed branches.

The peduncle (the lower un-branched part of the stalks) and the perianth (both the calyx and the corolla part of the flowers) are both without glands. The unseen (here) achene (the fruit containing a single seed) are 2 to 2.5mm long, shiny, and lenticular (biconvex lens-shaped).

The inflorescence is lax and tapers into the sheaths.


Not to be semantically confused with : Sweet Pepper (Capsicum annuum), Pepper-saxifrage (Silaum silaus), Peppermint (Mentha aquatica x spicata) or Water-purslane (Lythrum portula) [plants with similar names belonging to differing families].

Like Tasteless Water-pepper (Persicaria mitts) Least Water-pepper also does not taste peppery and has even narrower leaves. The flowers of Least Water-pepper are also more pink than those of Tasteless Water-pepper. The flowers also do not overlap.
