Golden Hearts or Floating Harts are a yellow nymphoides lily like plant that is hardy when planted in a small pot and grown in shallow water 3 to 12 inches deep. The water lily like pads come to the surface in spring and these bloom in summer in calm water with full sun.
Not a great plant for ponds with large koi as they will eat them. Plant in a 4 to 6 inch pot with loam soil.
