Description

Persicaria hydropiper is an annual herbaceous plant, usually 20–80 cm tall, growing erect or ascending. Stems are slender, branched, smooth, and often reddish-green. Like other members of Polygonaceae, the stems show swollen nodes covered by membranous ochrea. Leaves are simple, alternate, narrowly lanceolate, usually 3–12 cm long and 0.5–2 cm wide. The leaf surface is smooth, with entire margins and pointed apex. Leaves often contain pungent compounds and produce a sharp pepper-like taste when crushed. The ochrea is cylindrical, membranous, and fringed with short hairs. Flowers are small, greenish-white to pink, arranged in slender drooping terminal and axillary spikes. Flowers are bisexual with a 4–5 lobed perianth, 5–8 stamens, and a superior ovary. Fruits are small, shiny, three-sided achenes, dark brown to black at maturity, enclosed within persistent perianth segments.
