Floating primrose-willow (Ludwigia peploides) is a highly invasive aquatic perennial plant native to the Americas and Australia. It forms dense, fast-growing mats across the water's surface, outcompeting native vegetation, depleting dissolved oxygen, and interfering with recreational waterways and water management.
Plant ProfileAppearance: Features fleshy reddish stems that float on the water or creep along mud. It produces bright yellow, five-petaled flowers that typically bloom from mid-to-late summer.Growth: Submerged stems can stretch up to 2 meters (6 feet), while roots develop at the nodes to form expansive, thick mats.
Habitat: Thrives in shallow, slow-moving freshwater wetlands, ponds, irrigation channels, and river backwaters.
