Pond grasses, rushes and reeds make great marginal plants because they add a vertical dimension to the pond. Taller varieties also make a nice accent along the back edge of the pond, providing a backdrop or visual barrier.We have many varieties of all sizes, many with variegated foliage.
You can use rainwater to fill your pond, but keep in mind that it is very soft water. If you primarily use rainwater, be sure to check your pH regularly because it could become too low and cause serous problems.
