Bistorta affinis (synonymsPolygonum affine, Persicaria affinis), the Himalayan bistort,[2]fleece flower, or knotweed, is a species of flowering plant in the family Polygonaceae, native to the Himalayas (Tibet, Nepal, northern India, Pakistan, Kashmir).
Bistorta affinis is a creeping, densely tufted, mat-forming perennial, growing to 25 cm (10 in) tall by 60 cm (24 in) broad. The narrow elliptic leaves are white on the underside because of a waxy coating. Leaves are mostly at the base, 3–8 cm long, with the base narrowed to a short stalk. Leaf margins are entire or very finely toothed. The mid-vein is prominent. Cylindrical spikes of many pale pink or rose-red flowers are borne at the top of short erect stems, from midsummer to autumn. Flower-spikes are 5–7.5 cm (2–3 in) long, with densely crowded flowers. Stamens protrude slightly out of the flowers. Flowering stems are several, 5–25 cm tall, with very few smaller leaves. When the flowers have died, they tend to persist on the plant into winter.[3][4]
Habitat
Bistorta affinis is found in the Himalayas, from Afghanistan to eastern Nepal, at altitudes of 3,000–4,800 m (9,843–15,748 ft).[5]
