Best Aquatic Plants For Fountains And How To Maintain Them

Water fountains on their own may be one of the nicest additions to a landscape design, but if you’re looking to be original, you may prefer to add a little individuality to this piece of decor.

Many people opt to express their personalities by using flowerbeds, bushes, and other landscaping components to create harmonious scenes that capture the essence of the family or to outshine their neighbors.

When it comes to creating these works of art, every detail is important, so we want to help you make your water fountain stand out even more in its outdoor setting. And for that purpose, there is plenty of water flowers and greenery that could embellish your yard’s water fountain and make it look fantastic.

These plants are designed expressly for water life, but because they will not have access to natural nutrients from rotting plants, animals, and so on, you will need to supplement with fertilizer. Also, keep in mind that these plants do not like having water splashed on them all the time, so place them in the calmest part of the fountain basin.

Using plants as fountain accessories offer several advantages, including increased oxygenation for your fish, reduced algae growth, and increased water surface coverage.

Here is a list of the most common water plants you can add to your fountain:

Water Hyacinth (Eichhornia Crassipes)

Water hyacinths are particularly popular due to their ease of care and stunning violet flowers. With its abundant flower production for most of the year, its blossoms will undoubtedly bring color to your outdoor spaces.

Water Lettuce (Pistia Stratiotes)

Water lettuce has huge velvety leaves that look similar to spinach. In the correct conditions, this plant will also produce tiny white blooms. Just know that because this plant spreads out quickly, you’ll need a large fountain to make an excellent home for it.

Sensitive Plant (Neptunia Aquatica)

The Sensitive Plant, despite its name, is not at all sensitive. It has small fern leaves that close at night and flowers that bloom throughout summer. Depending on the seed family, flowers might be yellow or magenta.

Lucky 4-Leaf Clover (Marsilea Mutica)

Planting 4-leaf clovers in your fountain will not only bring you good luck but add a nice touch to it. This plant will cover any water surface with a blanket of clovers.

Moneywort (Bacopa Monnieri)

These water garden plants create a dense carpet of small shiny leaves that float to the surface of the water. In the summer, moneyworts are also known to develop little scented blooms.

Mosaic Flower (Ludwigia Sedioides)

The Mosaic Flower requires a water temperature of 72 degrees or greater, so it may not be possible in many climates, but it would be well worth it if you have a way to heat the water. These surface-covering plants produce rosettes of diamond-shaped leaves in green and red.

Water Poppy (Hydrocleys Nymphoides)

The Water Poppy resembles its land-loving cousin in appearance, with its simple, yet graceful pedals and a dark core.

Fairy Moss (Azolla Filiculoides)

If you’re searching for a low-level, shallow growing surface covering, Fairy Moss’ small fern-like leaves will do the trick. Not to add, as the season draws to a close, the leaves change color, creating a stunning autumn display.

Garden Upkeep And Watering

Except for the floating plants, all other plants should be placed in the water garden in their own pots or containers with the soil they grow in. The fountain’s water will cycle through and will not need to be changed. If the level drops due to evaporation, add more water regularly. Potted plants from the water garden can be brought indoors for the winter as houseplants.

Planting any marginal, aquatic, or floating plants should be done with caution. They may become invasive to local wetlands and streams if planted in their optimal setting.

How To Keep Water Plants In A Fountain

1 – Plant water plants in pots with no drainage holes, on heavy topsoil or clay loam. Light potting mixes and peat will offer insufficient weight to the pot, causing it to float and move around the fountain. To keep the dirt in place and provide weight to the pot, cover it with a one-half to three-quarters inch layer of small rocks or gravel.

2 – Lower the potted plants into the fountain at an angle to allow any trapped air to escape more freely. Set the plants at the proper depths, using piled blocks or overturned pots to boost height if necessary. Water lilies, for example, need to be 12 to 18 inches below the water when fully grown for their leaves to float on top of the water.

3 – Fertilize plants only if they appear to be in poor health and there is no alternative explanation for the problem. Overfertilization of aquatic plants can result in algae growth. Apply a slow-release 20-10-5 or 10-6-4 fertilizer in tablet or granular form to plants. Apply the fertilizer on a monthly basis, or as indicated.

4 – Plants should be moved indoors or into deeper water during the winter. Remove the plants from the fountain and clip away any dead leaves before moving them indoors. Place the pot in a plastic bag or tub of water and store it in a cellar or other location where the temperature stays above freezing but below 50 degrees Fahrenheit. Keep the plant’s roots moist by adding water to the bag or container as needed.

Final Thoughts
