The best barrel pond planting is a small mix matched to the container’s depth, sunlight, and local climate—not a crowded list of species. Start with a submerged plant and one or two potted marginal plants; add a compact water lily only if the barrel is deep and sunny enough. Floating plants are optional. Keep some water surface open and thin vigorous growth before it takes over.
Choose plants by the job they do
Different growth forms occupy different parts of a barrel pond. Combining a few can provide underwater cover, surface shade, and foliage above the water without filling the whole container.
Submerged plants: hornwort or tapegrass
Hornwort grows underwater and can float freely; tapegrass is rooted in the bottom. Both provide underwater cover and habitat, and their leaves release oxygen during photosynthesis. Either may multiply, so check growth regularly and thin it when needed. These functions are described by UF/IFAS Extension.
Rooted floating-leaf plants: water lilies
Water lilies root below the surface and send leaves and flowers to float on top. They need sun to bloom well, so they are a better fit for a sufficiently deep, sunny barrel than a shallow or shaded one. Look for a compact or dwarf type suited to container scale, and confirm its mature size and regional suitability with a local extension service or aquatic-plant specialist; no single cultivar is suitable for every barrel.

- LIVE PLANTS: Package includes 5 fresh water hyacinth plants (equevalent to 8 oz) with vibrant green leaves and buoyant bulbs for immediate pond use
- NATURAL FILTRATION: These floating plants help maintain water quality by absorbing excess nutrients and providing shade for pond fish
- EASY CARE: No soil needed - simply place these hardy aquatic plants on the water surface and watch them thrive and multiply
- POND COVERAGE: Each plant spreads 6-12 inches wide, perfect for decorating water gardens, koi ponds, and aquatic features
- GROWTH HABITS: Produces glossy, round leaves up to 6 inches wide with thick, spongy stems that naturally float on water surfaces
Marginal plants: foliage at the water’s edge
Marginals root in shallow water or saturated soil and grow above the surface. Examples in UF/IFAS guidance include lemon bacopa, lizard’s tail, duck potato (also called arrowhead), pickerelweed, rushes, sedges, cardinal flower, and blue flag iris. They vary in preferred depth, mature size, hardiness, and regional ecological status, so choose for your conditions rather than treating the list as interchangeable.
Floating plants: optional, and best kept in check
Floating plants can shade water and take up nutrients, but some spread quickly. Illinois Extension lists water lettuce and water hyacinth as examples; their suitability and legal status vary by location. Check local invasive-species and native-plant guidance before buying or releasing any aquatic plant, and remove excess growth so floating foliage does not cover the entire surface.

Match the planting to your barrel’s conditions
Before choosing plants, check the conditions they will actually get. Colorado State University Extension’s barrel-pond guidance recommends a flat site with six or more hours of sun per day. That is Colorado-oriented advice, not a universal requirement for every plant or climate; use the light needs of the species you select.
- Depth: Measure usable water depth and note whether a plant needs submerged roots, shallow water, or room for floating leaves. Supports can raise a pot to the right level.
- Sun: Match exposure to the species’ needs. Lilies in particular need sun to bloom well.
- Size and spread: Check mature dimensions and growth rate against the barrel’s limited surface and water volume.
- Winter conditions: Confirm whether the plant is hardy where you live and how it should be overwintered in a small container.
- Local ecology: Verify that a plant is appropriate and permitted in your area, especially before introducing fast-growing or non-native floaters.
Colorado State suggests two to three potted plants plus some floaters as a practical container arrangement. Treat that as a starting point, not a fixed quota: barrel size and plant growth vary, and a restrained planting is easier to manage.

Plant in separate pots and set each one at the right level
- Prepare the barrel. Colorado State University Extension recommends lining a half barrel with plastic to prevent substances in the wood from entering the water. Set it on a flat, stable location before filling.
- Pot plants individually. Separate pots or aquatic baskets let you position, remove, and thin plants without disturbing the rest of the planting.
- Choose a heavy planting medium. Illinois Extension warns that ordinary potting soil may float and cloud the water. For shoreline plants, use heavy clay; cover the soil with gravel if needed to hold it in place. Fully cover any fertilizer tablet with soil.
- Adjust planting depth. Place pots on bricks, stones, or inverted clay pots where necessary to bring each plant to its preferred water level. Solid supports displace water, so account for that if fish are present.
- Leave room to grow. Begin with a few plants and keep open water visible. Add or divide plants only as the barrel’s conditions and available space allow.
Avoid overfertilizing: excess nutrients can accelerate floating-plant growth. Top up water as it evaporates.
What plants can—and cannot—do for algae
Submerged and floating plants take up nutrients; floating leaves also shade the water. Together, those effects can help limit algae, but plants cannot guarantee an algae-free pond. In a 2015 article last updated in 2021, UF/IFAS Extension author Donna Legare writes of algae: “It cannot be totally eliminated, but can be controlled through creating a balanced ecosystem.”
Rank #4
- IMPORTANT: DO NOT ORDER IF ITS TOO HOT!! Please note that during times of extreme weather, live plants will suffer due to extreme temperatures. During winter, do not order live plants when temperatures are expected to go below 20F at the lowest point during the day. During summer, avoid ordering plants when temperatures are above 100F. Additionally, these plants will get damaged if your region experiences strong cold winds.

UF/IFAS gives 60–80% aquatic-plant surface coverage as general pond guidance. That is not a measured barrel-pond rule. In a small container, use it only as broad context: keep some surface open, observe how the water responds, and thin plants if they crowd the barrel.
If algae appears
Illinois Extension recommends reducing light and nutrient inputs; plants and shade can help. Check whether fertilizer tablets in plant pots are fully covered, since exposed fertilizer can add nutrients to the water. Colorado State Extension also recommends removing the plants, emptying the container, and refilling it if algae develops. That is one possible reset, not the only response.

Prevent mosquito problems and plan for winter
When larvae appear
A neglected container can become a mosquito breeding site. Illinois Extension identifies Bti mosquito dunks as an option; follow the product label and local guidance if you use a larvicide. Overflowing the barrel may flush some larvae, but it is not guaranteed to remove them all: larvae can swim toward the bottom.
When temperatures fall
Small containers may not protect plants through winter, particularly in cold climates. Colorado State Extension advises bringing tropical plants indoors before frost. Keep hardy plants cool without letting them freeze or dry out. The right approach depends on the plant and local winter conditions, so check regional guidance for the species you grow.
