This is a picture of the floating hearts in my pond.  The floating heart is a water lily like plant that looks and grows much like a water lily.  The miniature size is ideal for small ponds and containers.   I planted mine right in my bog area anchored at the rocks edge.  It grows freely across the pond water in only a few inches of water.

This is a hardy plant in Zones 5-11.  It is very free-flowering and a fast grower with a running spread.  It ideally grows in 4-24 inches of water.  The leaves are slightly toothed and an even green, sometimes showing a hint of brown throughout the leaves.  It will bloom throughout the growing season with little to no care.
