A combination of white flowers, white seed structures and attractive foliage makes a nice addition in the shade garden. Spreads by both rhizomes and seed, with ability to shoot seed up to 10-13 feet through the air. However, unlike many other members of the Polygonum genus, it is generally not considered invasive or weedy. Sometimes has a chevron-marking on the leaves (see photo). Cultivars available with pink to red flowers. Occurs naturally in floodplain forests, dry woodlands, rich deciduous forests, and thickets.
