Persicaria amplexicaulis, the red bistort[2] or mountain fleece, is a species of flowering plant in the buckwheat family, native to China, the Himalayas, and Pakistan. It is a damp-loving herbaceous perennial growing to 1.2 m (4 ft) tall and wide, with heart-shaped pointed leaves, downy beneath, and narrow spikes of rose-red or white flowers in summer.[3][4]

The specific epithet amplexicaulis means "clasping the stem", and refers to the leaves' habit of growing around the stem.[5]

Numerous cultivars have been developed for garden use, including 'Firetail'.[6]
