One of the best parts of having a pond or water garden is adding plants around the pond and in the pond. Flowering aquatic lilies bring a lovely touch to any pond as bright flowers grow around lily pads. Fish love to swim in and around various aquatic plants and the shade they provide and oxygenation they give are very important to the health of any pond. Floating islands can also be added and marginal pond plants can be added as rooted seedlings or even seeds can be sprinkled on to floating islands to create unusual floating islands of grasses and flowers. Hyacinth and duckweed can help maintain a clean pond and also add a realistic touch on the edges of the water garden.
