Marsh dewflower (wart-removing-herb) is an annual, emergent plant that invades wetlands in the southeastern and northwestern United States. Plant stems are succulent, form roots at the nodes, and grow prostrate along the ground. Stems are 12-30 in. (30.5-76.2 cm) long. Leaves are alternate, lance-shaped, and up to 3 in. (7.6 cm) long. In September to November small, pink, 3-petaled flowers occur singly or in small clusters at the apex of the stems and in the leaf axils. Marsh dewflower invades water edges and marshes and often grows immersed. It forms dense mats that out-compete native vegetation. Marsh dewflower is native to eastern Asia and was accidentally introduced into the United States, in South Carolina, around 1935. |
