10 Must Have Submerged Deep water Pond Plants
Submerged pond plants play an essential role in maintaining a healthy pond. Releasing oxygen into the water and taking up excessive nitrate levels at the same time, they create a perfect balanced environment for all pond life. Some deep water plants are just water foliage plants whilst others produce underwater and water surface leaves that take on a completely different shape when they grow out of the water.
Sagittaria Graminea (Narrow Leafed Arrowhead)
This plant can be categorized both as a marginal and a submerged aquatic plant. It has narrow evergreen submerged leaves that oxygenate the water and make a favourite breeding ground for Newts that fold the leaves around their eggs for protection. This form of Sagittaria, also produces a mass display of attractive white flowers in the spring and early summer.
Vallisneria Spiralis (Tape Grass)
This underwater oxygenating plant works wonders in maintaining crystal clear water. Also another favoured plant for Newts to lay their eggs on.
Justicea Americana (Water Willow)
We might just be the only water garden nursery that offers this rare but easy to grow beauty. Water Willow produces stunning, Orchid looking flowers and small elongated leaves that emerge about 12 inches out of the water throughout the summer.
Persicaria Amphibian (Amphibious Bistort)
Another great submerged plant that produces pink flowers that stand up out of the water throughout the summer. This plant has elongated floating leaves resulting in a very attractive natural look.
Ranunculus Aquatilis (Water Crowfoot)
Water Crowfoot looks great everywhere and grows in still and flowing water. It has submerged leaves that look completely different when growing out of water when water levels are low. It’s an excellent oxygenating plant and things just get better. This amazing plant produces hundreds of attractive, floating green leaves (size of a 10p), and a carpet of floating white flowers throughout the spring and early summer. I believe a definite MUST for all ponds and streams.
Stratiotes Aloides (Water Soldiers)
This very interesting plant is always sold incorrectly as a free floating pond plant. In fact, it is a submerged aquatic plant that grows up to the water surface on long roots that feed off the rich silt from the bottom of the pond. Water Soldiers emerge out of the water in the summer giving the appearance of floating Pineapple tops with small white flowers in the leaf axils. The underwater leaves produce oxygen and are another favourite for breeding Newts.
Orontium Aquaticum (Golden Club)
This stunning plant is more of a deep marginal plant rather than a deep water submerged plant so it’s another plant that is always categorized wrongly. However, due to its popularity and incorrect category listings, I have decided to list it in this article. Golden Club has the most unusual, elongated white and yellow flowers that have no petals. It takes time to establish but this very low maintenance plant is well worth the investment.
Hottonia Palustris (Water Violet)
This oxygenating plant can be a bit fussy. It favours clay bottomed ponds but will also grow quite happily in manmade lined or fibreglass ponds but only if they are established with a good 3-4 inches of silt. Water Violet has ferny looking, bright green underwater foliage and in late spring/early summer sends up a sparingly amount of stems that emerge and flower about 12 inches out of the water.
Apponogeton Distachyos (Water Hawthorn)
This one has a long history of being the most popular of all the submerged pond plants and for good reasons! It produces large, elongated, oval shaped glossy green leaves that float on the water surface along with masses of attractive, vanilla scented flowers that also sit on the water surface. In the heat of the summer, this plant goes dormant and quite literally disappears as it dies back to a bulb state under the soil, silt or clay. When the water cools as autumn approaches, this amazing pond plant comes back to life and will flower right through the winter and spring until the water becomes warm again. Apponogeton leaves can however, look a bit frost damaged but always replaced with fresh green leaves within a few days after a cold spell.
Callitriche Hamulata (water starwort)
This species of Callitriche is very rarely sold though it is actually a very attractive, easy oxygenating plant to grow. It grows much denser than Callitriche Stagnalis. Callitriche Hamulata is a terrestrial plant, (growing submerged and on land), making it ideal for planting at the water’s edge where it forms low dense mats of bright green foliage, creating a safe entrance and exit for all kind of pond visiting wildlife.
