Why have water plants for ponds?

Pond plants utilise nutrients in the water for their growth. this means they take some of the load off the pond filter. Excess nutrients in your pond can lead to poor fish health and problems such as algae growth, which can turn your water cloudy or green.

Plants also provide cover for your fish from the harsh sun and birds such as kookaburras and cranes. Shade from the sun also lessens the chance of your pond having algal blooms.

On top of all of this, they make for an interesting environment for your fish, giving them a home that is ever-changing to explore and find food within.

Aquatic water plants for fish ponds

Selecting Aquatic plants for your fish pond

When selecting fish pond plants, keep in mind the depth of your pond, the amount of sun it is receiving and the types of fish you have.  All of this will affect the type of aquatic plant you choose. All plants that come out of the water, such as reeds, papyrus, irises and marginal plants require shallow water of around 20cm in depth (they just want to have their feet wet!).  If your pond is deeper than this, then you may need to prop up your plants on some bricks or rocks.

Water lilies like water to be at least 35cm deep and need lots of sun in the summer to flower well. Lotus also like plenty of sun and ideally to stay contained to the water in their pot. That way when they are fertilised all of the nutrients is kept close to the roots.

All our water plants come potted, and usually, you just plonk them into the water when you get them home.  We package all of our water plants in a tough plastic bag or waterproof box, so they won’t leak in your car.

Our expert staff are always on hand to help talk you through the process of choosing what plant will perform the best for your specific pond. We are more than happy to do this in store (closed mondays). If not please feel free to give us a call or send through an email and we can make some recommendations for you that way 🙂

We also stock a range of aquarium plants for the indoor fish tank.

Watergardening tips

Of course, every pond plant will have slightly different requirements – but there are some general rules that, when followed, will ensure your healthy plants!

It is important to select the correct aquatic plant for the amount of sunlight you receive. Most pond plants love full to partial sun, for those with shady water we recommend trying out arum lilies, king tut papyrus and umbrella grass. (please have a look at our pond plants for sale section on this page for a better idea on which plants have high light requirements)

If you want to get the most out of your water plants, we have one industry secret… fertiliser! We reccomend fertiliser for most flowering plants, particulalry water lilies and lotus but really you can use it for any plant you want to see some extra growth out of. It is very important to note however, that you CANT use your standard garden fertiliser for water plants, particulary if you have fish. These fertlisers can cause algal blooms and add harmful chemicals to the water. You should be using a specialised water plant fertiliser like the ones you will find HERE

How to repot your pond plants

How to repot waterplants

All you need is some overgrown water plants, water plant soil, some spare pots and some newspaper

1)  Line the pot with a bit of newspaper that will block the holes of the pot.
2) Separate an individual water plant that has grown out of its pot.  Try to cut the plant so that it retains much of its new growth roots.  Cut-away any old leaves.
3)  Place the root ball of the plant into the pot (if there is no root ball, then just dangle the roots into the pot, holding the water plant at the eventual level that you wish to have the plant sitting.
4)  Pack the soil into the pot so that it will support the plant at the right level, around 20mm below the top rim of the pot.
6)  Fill in the remaining 20mm with gravel (this will prevent your naughty fish from digging into the water plant soil!).
7)  Place the water plant into the conditions that particular species likes (sunny?  shady? correct water depth etc).

Water Lilies for Sale

Nymphea species

Everyone LOVES waterlilies! So we have lots of water lilys for sale!  Their classic flowers are big, beautiful and evoke Japanese water garden ambience. We love them because when one bloom opens, another is usually pushing its way up to keep the display going for a large part of the year. You can’t get much better than these in your pond.  We recommend getting a mixture of both temperate and tropical water lilies so that the flowering is more evenly spread out over the spring, summer and autumn seasons.  Temperate (sometimes referred to as “hardy” water lilies) are more likely to keep some leaf cover over winter as well.



  • Best in full sun. Will cope with limited semi-shade but… less sunshine means less blooms.
  • Floating leaves spread up to 1.5m in diameter.
  • Can be grown in small ponds but needs to be fully submerged in up to 60cm water depth.
  • Low maintenance, remove dead leaves and flower heads as required.
  • Provides shade for fish during summer months and some camouflage for fish to help prevent bird attack.


    Warning! Koi like to nibble around the root zone of water lilies so we recommend a layer of gravel on top of the pot to discourage fish from digging.

Temperate lilies vs Tropical lilies

temperate lily

TEMPERATE (Hardy water lilies)

Hardy water lilies are the toughest water lilies often from temperate climates with cold winters. They range in colour from white to yellow, pink and red and include gorgeous two-colour peach/orange/yellow varieties. They have rounder leaves, their flowers tend to sit closer to the water and they usually flower earlier than tropical lilies.

  • These water lilies keep their leaves throughout winter.

TROPICAL WATER LILIES

Even though Tropical Water Lilies come from warmer more tropical regions, the varieties we sell do well in temperate NSW conditions. Tropicals tend to have taller flowers, pointier leaves, and continue to flower until late in the season. Their flowers range in colour from whites and pinks to purples, mauves and blues.

  • These water lilies die back completely in winter but re-shoot in early spring.
