Botanical name: Murdannia lanuginosa Family: Commelinaceae (dayflower family)
Marsh dewflower is an annual, emergent plant that invades water edges and marshes, often growing emersed. It forms dense mats of vegetation which out-compete native vegetation. Plant stems are succulent, root at the nodes, and grow prostrate along the ground. Leaves are alternate, lance-shaped, and up to 3 inches long. The flowers occur at the ends of the stems or arise from the position between the stems and leaves (leaf axils) Flowers can occur singly or in clusters of 2 to 4. All flowers occur on short flower stalks and consist of 3 purple, blue, pink, yellow, or nearly white petals that are approximately 1/3 inch long.
