Habitat: This perennial aquatic plant is most commonly found in slow moving rivers, ponds, and lakes.
Native Range: Asia and Europe
U.S. Distribution: Introduced to many U.S. states
Local Concern: Yellow floating heart can create dense mats that shade out native aquatic plants, decrease oxygen levels, increase mosquito breeding habitat, and impede boating activity, fishing, and swimming. Fragmented pieces of plants can establish new populations and seeds are engineered to disperse by attaching to the feathers of waterfowl.
