Smartweed, swamp
 

Smartweed, swampAn erect perennial from rhizomes. It typically occurs in low, wet areas of no-till crop fields but also in ditches or along the shorelines of ponds and marshes. Plants may reach as much as 3 feet in height. Leaves occur alternately along the unbranched stems and are oval to lanceolate in outline and are up to 2-1/2 inches wide with wavy margins that taper to a point. A membranous sheath called an ochrea surrounds the stem at the base of each leaf. Flowers are pink to rose-colored and occur as 1- to 3-inch spikes at the ends of stems.
