Fanwort has fan-shaped leaves, hence its name. This delicate plant has elongated floating leaves along a slender stem that can grow to more than six feet tall. The dark green submerged leaves are opposite or whorled. Fanwort can have a single white flower at the tip of the stem that stands slightly above the water’s surface. Three to ten feet of water are ideal for fanwort.
To differentiate it from other similar-looking plants, look for both the submerged and floating leaves, although the narrow diamond-shaped leaves are sparse.
Fanwort is common across the United States.
