Persicaria amphibia

Persicaria amphibia, commonly known as amphibious bistort, is a versatile perennial that can grow both submerged and in damp soils, forming upright or floating clumps of lance-shaped green leaves. In summer it produces dense spikes of small pink flowers, creating a delicate display along pond margins, shallow water, and wet meadows.

This species is valuable for pollinators and aquatic biodiversity, providing habitat and stabilising pond edges. Its upright, clump-forming habit and tolerance of consistently moist, waterlogged, or shallowly submerged soil make it ideal for pond margins, wetlands, and naturalistic water features.
