Persicaria hydropiperoides
Also called False Water Pepper, Mild Water Pepper, Mild Smartweed, Mild Waterpepper, False Waterpepper, Northeastern Smartweed
Persicaria hydropiperoides, commonly called swamp smartweed, mild waterpepper, false waterpepper, or sometimes simply waterpepper, is a species of flowering plant in the buckwheat family. It has a widespread distribution across much of North America and South America. Its preferred habitat is in moist, saturated to inundated soils growing in full sun to partial shade; such as swamp forests, marshes, streams, shorelines, and ditches. It is sometimes semi-aquatic.
Swamp smartweed is quite variable and is sometimes divided into several varieties, some of which may be better treated as species in their own right.
