Two of the most popular floating pond plants would have to be water lettuce and water hyacinth. These species are a staple in most backyard and man-made ponds across North America. While they each have their own advantages, they also have disadvantages that can be harmful to your pond’s unique ecosystem.
Water lettuce is one particular type of plant that can add volume to your pond. Commonly found in natural waterways in the south, these plants have roots that hang beneath the surface. Their leaves, which are thick and form a basket-like shape, can span up to 12 inches long. The basket-like appearance is what gives them the name of water lettuce. These pond plants can form dense mats making them a highly invasive species for other plants and fish in your pond. Cutting the top growth helps in controlling these plants.
Water Hyacinth is a floating plant with broad leaves that float on the surface and a root structure that is submerged below. These pond plants have a single stalk that reaches up to 16” in height and contains several floor buds. These flowers can bloom in a wide range of colors including white and pink. One drawback is that these plants can be very invasive and take over a pond if not controlled properly. Aquatic pesticides or controlling the top growth are two ways to go about this.
No matter which of these pond plants you choose they will make your pond flourish.
