An unusual variety of bistort, grown for its dramatic foliage that changes colour with the seasons. In spring, its velvety, burgundy-plum, long heart-shaped leaves are set off by a silvery, metallic, chevron-shaped marking, which gradually turns red as the foliage becomes greener. It is fairly vigorous, though not invasive, and forms a natural mound, with sprays of tiny white flowers in late summer. Try it as an eye-catching groundcover plant in moist, even boggy soil or beside water or as a handsome plant in a container.
