The Crested Floating Heart has small heart-shaped leaves and floats on the water, but is rooted in the soil. It was introduced from Asia in the aquatic plant trade, and it has become naturalized, displacing the native species. Stalks with white flowers have five petals, and a distinctive white ruffle running along the middle of the petal, which is a key to distinguishing it from the native species.
