Description:
Yellow floating heart is a perennial, waterlily-like plant that carpets the water surface with long-stalked heart-shaped leaves. The showy five-petaled yellow flowers occur on long stalks and rise a few inches above the water. Yellow floating heart is a native of Eurasia and the Mediterranean area and has been introduced into Washington, particularly along the Spokane River near Spokane. Because of the attractive yellow flowers, this plant is being sold as an ornamental water garden plants. Lake residents are strongly discouraged from planting yellow floating heart in lakes or natural waterbodies. These plants appear to be aggressive growers and sometimes "hitchhiker" plants such as hydrilla can also be introduced to our lakes when nursery or mail order species are planted.

• Mechanical: Cutting, harvesting, covering with bottom barrier materials should work
• Biological: None known at this time; crass carp don’t eat water lilies (very similar plants) in WA
• Herbicide: Aquatic glyphosate may work-permits and special licenses required. Refer to the State Noxious Weed Control Board site
