Garden pond plants such as the water lily are grown in 10"-18" of water over the pot or crown of the plant.
One of the great benefits of deep water plants is that butterflies are attracted to the nectar found in the flowers.
The plants are a necessary part of the overall pond environment because they help filter the water, provide shelter for fish, both adult and fry and shade the pond.
The plants also aid in reducing nitrate levels, and absorb tremendous amounts of the organic matter produced by your fish and their food.
The plant stabilizes water chemistry and are a necessary player in some fish breeding.

And another is the yellow pond lily with large heart shaped pads.
Treat your deep water plants as annuals or bring inside for the winter months.
