Oxygenating Plants

Oxygenating plants are placed in the water to put oxygen into the water itself. They are often used to maintain the balance of the pond and prevent a build up of carbon, which they also use for growth.

Bacopa Caroliniana

Produces a lemon scent, this is an interesting plant which grows to the surface. Once above the surface it blooms with small blue flowers. Its spread should be kept in check in small ponds.

Callitriche Stagnalis

Provides a mass of stems which are home for minute life. These are small tender plants that grow in a tight mass.

Ceratophyllum

A useful plant in shaded situations, it is usually found free floating or lightly anchored to the pond bottom. In colder months, the plant will blacken during dormancy.

Egeria Densa

A fast-growing plant which absorbs lots of nutrients from the pond. It also helps reduce blue-green algae growth. Also suitable for deeper ponds.

Eleocharis Acicularis

A plant with rush-like leaves and flowers produced on spikelets. A relatively dense plant offering shelter for small life and fish. Suited to part shade and full shade.

Elodea Canadensis

An excellent oxygenator, however it should not be released due to its invasive nature. Not suited to small ponds due to its spread.

Fontinalis

Forms a congested mass with long, branched stems with moss-like foliage. An excellent plant in ponds with running water.

Hippuris Vulgaris

A plant which is useful for removing build-up of methane from the floor of the pond. Suited to a site with full sun or part shade. Native of the British Isles.

Hottonia Palustris

A relatively hardy plant. Produces violet flowers which have yellow throats. Prefers ponds which are clear.

Hydrocotyle Nova Zealandiae

A fast-growing oxygentating plant. Has rounded leaves which emerge from the water and grows into floating mats. Should not be allowed to spread into the wild.

Hydrocotyle Sibthorpiodes

A good-looking perennial which forms carpets on the surface of four leaf clover-like foliage. Site in part shade or full sun.

Lilaeopsis Brasilensis

Forms a lawn-like carpet at the bottom of the pond, though the foliage can appear above the surface in shallow ponds. Suited to full or part sun.

Ludwigia Glandulosa

A submerged plant which is an excellent oxygenator. Its foliage usually pokes just above the surface. Best suited to ponds or streams.

Marsilea Quadrifolia

Although this plant has the appearance of a clover, it is actually an underwater Fern. The leaves rise to the surface and create a decorative pattern. Native to the British Isles.

Myriophyllum Crispatum

Produces long stems with feather-like leaves and small red flowers. Also able to scramble on to the surrounds of the pond and provides a diverse habitat.

Myriophyllum Spicatum

This plant remains under the water. The red foliage variants can cope with deeper water, up to as much as four metres. Native to the British Isles.

Potamogeton Crispus

A perennial with submerged stems and leathery, floating leaves. Its flowers are small and white.

Potamogeton ‘Malaianus’

An excellent oxygenator found in many natural water bodies. Must be kept under control as it spreads readily.

Potamogeton Octandrus

Produces narrow, eliptical leaves which are bright green. Also produces short, spiked fruit branches. Keep under control in a small pond.

Potamogeton Perfoliatus

Features semi-translucent leaves which are emerald green. Spreads fairly readily so should be kept under control. Site in full sun or part shade.

Proserpinaca Palustris

A very good plant for Tadpoles which use it as a food source. Found more commonly in still or slow moving water. Place in full sun or part shade.

Ranunculus Aquatilis

Baring kidney-shaped leaves which either float or are submerged. Has an attractive white and yellow flower which is held above the water surface. Excellent for pollinators.

Sagittaria Graminea

A small plant with narrow lance-like leaves and small white flowers. Good for bees. Best suited to small ponds or water features.

Sagittaria Filiformis

A submerged perennial, the leaves are long and ribbon-like. Ideal for a location which received full sun or part shade.

Scirpus Cernuus

Resembles a fibre optic light with long spiked leaves with a tiny flower atop. Suited to either status of an oxygenator or marginal.

Vallisneria Americana

A good plant for any wildlife inhabiting the pond. Best placed in a site which received full sun or part sun.

Vallisneria Spiralis

Produces long stems with feather-like leaves and small red flowers. A good plant to diversify the wildlife in the pond. Also scrambles around the edge of the pond.
