Yellow floating heart
About This Species
Native to Eurasia, Yellow floating heart is an aquatic species that resembles water lily. It spreads both by seed and vegetatively making this species extremely difficult control. It forms dense mats that impede water flow and disturbs sensitive aquatic habitats. It was initially used as an ornamental pond plant but has escaped cultivation and has the potential to cause major damage in BC – if you see this species, be sure to report it immediately. Yellow floating hear prefers depths of 0-4 m and slow-moving water.
How to Identify
Yellow floating heart has round, floating leaves 3-15 cm in diameter that sit on the surface of the water, typically found growing in dense mats. When flowering, the single yellow flowers appear on stalks above the leaf. The fruit is a flattened, oval capsule that turns from green to brown as it matures and ripens.
