Floating Heart in Dolloff Cove (note dragonfly for scale) - photo by Don Yurewicz
Floating heart is a small floating perennial. Leaves are small, approximately 1-1.5 inches across, and heart-shaped. The leaves may be reddish to purplish in color. Flowers are white.
Identification Tips: The leaves are often confused with those of the yellow water-lily but are only about the size of a 50 cent piece, and the shape resembles a heart, with the same soft v-shape of the yellow water-lily. Floating heart has a small white flower that can be found in mid-summer; yellow water-lily has a large yellow flower that blooms most of the summer.
