Yellow Floating Heart Nymphoides peltata
Ecology and Natural History: Yellow floating heart is native to Eastern Asia and the Mediterranean. It was introduced to the United States as a water garden plant. It grows in lakes, ponds, swamps, and channels with slow-moving water. It can tolerate anaerobic conditions.
Impacts of Introduction: Yellow floating heart typically develops monotypic patches that crowd out native plants. The dense patches also create stagnate, low-oxygenated water. The floating mats block sunlight for plants and algae and can impede boating.
