|A pond is a wonderful way to add a little something different to your garden landscape.
There are many different types of water plants out there for different ponds of different sizes. Here are some classifications of waterplants and how they grow.
Submerged water plants.
Plants that grow entirely under water are called submerged water plants. They are also called oxygenators for their ability to add oxygen to the water during daylight hours. Submerged plants provide coverage for fish and other aquatic life as well as adding beauty to the water. Many have colourful foliage that glistens under water and several have flowers that float on the waters surface. They are very easy to grow and generally require little care to make their important contribution to the ecology and life of the pond.
examples: parrots feather, water violet, mares tail
Floating water plants
Plants that sit on the waters surface with no need of a pot or soil are called floaters. Floaters are extremely easy to grow and some even flower. All they need is a container that holds water and they will grow right on the deck or patio. Their roots dangle down into the water drawing nutrients that could otherwise cause an algae bloom. Floaters are usually bought fresh every year.
examples: water hyacinth, water lettuce, frogbit, azola
Marginal water plants
At the edge of the pond are the "marginals". These plants grow with their roots in the soil but with most of their foliage above the water surface. Some grow in soil that is only moist, while others like to be in soil that is a few inches under the water. Some are clump forming, and others are rambling with their foliage trailing into the water. Both flower and foliage can range from red to orange to pink , to green and white striped.
examples: aquatic mint, pickerel, water zinnia, water forget-me-not, cyperus, pennywort
Waterlilies grow with their roots and stems below the water and their foliage floating on the waters surface. Their leaves are round and look like floating green pads on the water. Waterlily flowers are many petaled and vary in shape from round to cactus-like. Some float on the water while others are held inches above the surface.
Waterlilies are classified into two broad groups. Hardy lilies survive the winter. Tropical lilies cannot withstand a winter freeze and need special care during the colder months.
Hardy lilies come in many colours. with different mottling on their pads. Some are solid green while others have a mottled look to them. Hardy lilies flower during the day and most require full sun. For more shade tolerant varieties look to the reds, as the flowers tend to burn in hot hot sun.
Plants that are not waterlilies, but grow like them are called waterlily-like. Some, such as the water snowflakes have dainty star shaped flowers and rounded leaves. Others, such as water poppies have creamy yellow flowers that resemble single roses. Water hawthorne is a very hardy lily-like plant that prefers cooler weather. With blooms in spring and fall it is a great companion plant with the water lilies.
