Types of Water Plants
Floating plants such as water hyacinth and water lettuce help reduce algae in the water garden. Water hyacinths reproduce rapidly; you may need to cull some of the plants from time to time. If you live in a warm climate, don’t throw water hyacinths into open water such as canals, ponds, etc.; it can be an invasive plant.
Most oxygenating grasses grow submerged deeply in water and either sit at the bottom of the pot or float on the water’s surface. Oxygenating grasses help maintain the proper pH balance and oxygen level of the pond’s water. Examples: anacharis (Egeria densa), fanwort (Cabomba caroliniana), feather grass and blood grass.
Bog plants should be placed so that the water level just covers the soil. In nature, bog plants grow naturally in shallow water at a pond’s perimeter. In a pond pot it may be necessary to set bog plants on top of rocks, on top of small inverted pots, or hang them from the edge to create a more shallow water environment. Perennial hibiscus even make fantastic bog plants.
Marginals grow in 1 to 12 inches of water between the shore and deeper water. Marginal plants are favorites in small container water gardens and usually sit at the bottom of the pot. Examples: horsetail and yellow iris (Iris pseudacorus).
Deep-water plants such as water lilies need at least one foot of water above their roots, a few square feet in which to spread their foliage. Water lilies help cool the water which reduces algae growth and maintains oxygen levels. Plus, they have gorgeous blooms!
