Persicaria hydropiperoides is quite variable and is sometimes divided into several varieties, some of which may be better treated as species in their own right. In general, Persicaria hydropiperoides is a rhizomatous perennial herb growing upright or erect and approaching a maximum height of one meter (40 inches). Roots may emerge from nodes on the lower stem. The bristly lance-shaped leaves are around 10 centimeters (4 inches) long. The leaves have sheathing stipules known as ochrea. The spikelike inflorescence produces many pinkish flowers each about 3 millimeters wide. Learn more about Swamp Smartweed
