Outdoor home pond plants add many important things to your pond. Outdoor home pond plants, also referred to as aquatic plants or water plants, are unique in their ability to grow in water and water-soaked soil. Some grow under water, some grow partially submerged and some grow with part of their leaves either above water or floating on water with submerged roots. Outdoor home pond plants will not only add beauty to the pond, but can also clear out and oxygenate the pond. The best home pond plants are those that easily acclimate to the environment, making maintenance easier, and which add beauty to the garden. These plants must thrive in ponds without overwhelming them.
