Identifying the origin of yellow floating heart, Nymphoides peltata
Yellow floating heart, Nymphoides peltata, was introduced in North America in the late 19th century as an ornamental plant. Since its introduction, it has steadily spread and been repeatedly introduced across the United States and parts of Canada. Where introduced, yellow floating heart can outcompete native vegetation and phytoplankton, and reduce oxygen in the water. In this project, CABI is helping to identify which area(s) in Eurasia Nymphoides peltata was introduced from to North America and is conducting surveys for potential European biological control agents.
