The hornwort is a cosmopolitan plant that can be found in many bodies of water around the world. We found the free-floating stem plant in huge populations in a tributary of the Rio Miranda on the edge of the Pantanal in South America. The growth rate of the stems is enormous, so they have to be constantly pruned. Ceratophyllum is considered a "miracle weapon" against algae growth. The explanation is quite simple: the plant is a strong nutrient consumer and removes the algae's food source. The use of hornwort is recommended for every new aquarium.

Excellent quality, but should be shipped without slugs.

The quality and proportions of the plant are very good, while the negative is that it was contaminated with snails.

Salvinia auriculata (Salvinia auriculata)
Salvinia auriculataSalvinia Auriculata (Brazilian salvinia) is a floating plant native to South America. It grows moderately quickly so that its population can be controlled. Easy to grow. Absorbs nitrogen to combat algae. Propagates by spreading.Difficulty of cultivation: easy to mediumLight requirement: medium to highCO₂ requirement: lowHeight of the adult plant: 0.5 cmGrowth: moderate to fastTemperature: 22 - 24°CPlacement in the aquarium: SurfaceOrigin: South and Central AmericaCup diameter 6 cmSalvinia Auriculata (Brazilian Salvinia) is a floating ornamental plant. It is native to the calm, still waters of South and Central America. It can be found from Paraguay to Cuba. It owes its popularity above all to its original appearance. Its small oval leaves with a diameter of 10 mm cm are arranged opposite each other on an elongated leaf stalk. These leaves are covered with fine hairs that trap air bubbles, allowing them to float. Depending on the light intensity, they are wavy or flat. Salvinia forms a third type of underwater leaves on which the spores are deposited.Like all floating plants, Salvinia is recommended for shady waters . Its great appetite for nitrogen and phosphorus compounds makes this plant a good ally in the fight against algae. Salvinia has low light and nutrient requirements. It grows well in both moderate and strong light. As a floating plant, it does not require a substrate but draws all the necessary nutrients directly from the water. During the vegetation period, it reproduces by spreading, whereby the growth rate is moderate. This makes it easy to control its growth and remove excess plants. It grows to a length of 3-6 cm and likes warm, humid air, so it is advisable to use a glass or cover when growing it.It should be placed in such a way that no condensation falls on the plants. It adapts very quickly to the new parameters. However, it should be borne in mind that it will die if there is too little light. It thrives best in soft to medium-hard water at 22-24°C. The in vitro culture of plants is carried out in tissue culture laboratories. Thanks to the sterile production conditions, the cuttings are free from snails, algae or pathogens.Planting:The plant must be removed from the cup and thoroughly rinsed of the gel under running water. This is best done by placing the plant in a container of lukewarm water. Most of the gel will then fall off by itself. Place the plant on the surface of the water.

Hydrocotyle verticillata - Whorled pennywort, American. Water pennywort
Hydrocotyle verticillata (mushroom plant, American pennywort) max. growth height - 20 cm Country of origin  North and South America Suitability Aquascaping, community aquarium Type   family Apiaceae Genus Hydrocotyle Propagation Side shoots Growth rate medium pH 5 - 8 Water hardness 0 - 15 °dh Notes   This water pennywort is very decorative due to its umbrella-like leaves and is suitable for the foreground to midground. Unlike H. leucocephala and H. tripartita, it grows rather slowly; the water temperature should not be too high. We found magnificent stands in shallow water in the Rio Sucuri, Brazil. The water temperature was 23 °C; the water was crystal clear with a high CO2 concentration. Hydrocotyle verticillata looks very natural in the middle of a Hemianthus carpet, with small ‘umbrellas’ protruding from it.

Limnobium laevigatum In-Vitro - a dainty floating plant Limnobium laevigatum is a dainty floating plant for open aquariums and for the garden pond or water trough. However, this South American plant is not hardy and therefore, needs to be overwintered in a warm place. In the right conditions, the plants spread quickly and, bit by bit, develop into a dense carpet of plants. Very long root beards can form in places, providing good protection for young fish in the aquarium

Dwarf water lily - Nymphaea pygmaea rubra
Dwarf water lily Nymphaea pygmaea ‘Rubra’ red (18cm)The dwarf water lily Nymphaea pygmaea ‘Rubra’ brings an elegant splash of colour to the water’s surface with its red flowers. Thanks to its compact form, it is particularly suitable for smaller garden ponds as well as mini ponds and bowls. Ideal if you want a water lily that doesn’t take up too much space.Dwarf-form water lily – suitable for small water areasFlower colour: redGrowth: compact, for a controlled leaf areaArea of application: Garden pond, mini pond, tub/bowlTechnical dataBotanical name: Nymphaea pygmaea ‘Rubra’English name: Dwarf water lilyFlower colour: redPlanting depth: -10 to -40cmFlowering period: June to September Pot size: approx. 18 cmWith the dwarf water lily Nymphaea pygmaea ‘Rubra’ you bring the typical water lily atmosphere into the garden – even if your pond is rather small or you want to plant in a mini pond or tub. Dwarf water lilies are designed to unfold a harmonious effect in a limited space: Floating leaves on the surface and an attractive blossom, without the water area being quickly completely covered. The ‘Rubra’ variety creates an elegant, easily visible splash of colour with its red flowers.Especially with smaller garden ponds, balanced planting is crucial. Water lilies that grow too vigorously can quickly dominate the surface and “close” the water effect. In comparison, a dwarf water lily remains more compact and is therefore a good choice if you want a calm, well-kept look and nevertheless do not want to do without the classic water lily eye-catcher. ‘Rubra’ is particularly effective when positioned so that you have a good view of the flowers from your seat or terrace – as the red shades clearly stand out against the water and greenery.For establishing, stable placement is important, ideally in a planting basket or a suitable container. This way the rhizome lies undisturbed, and you can adjust the position if necessary. If you are looking for a compact water lily with a strong colour, Nymphaea pygmaea ‘Rubra’ is a fitting choice for a natural yet controlled pond design.Note: We make every effort to ensure that our plants arrive healthy and undamaged. Despite the greatest care, it may occur that plants are slightly damaged during postal delivery or by other unforeseen events. This includes both brown leaves and bent branches. We accept no liability for this. Do not plant in open waters such as lakes or biotopes. Zoo-Roco tip: Put dwarf water lilies in a planting basket so you can easily adjust their position. If the plant is still small at first, start out higher (shallower) and lower them later – this often encourages quicker growth and flowering.

As the garden comes back to life after winter, it provides a radiant focal point by the water with its yellow flowers from March to May (III–V). Especially at the pond edge, this is particularly valuable: many marginal plants only really start to grow strongly later on – the marsh marigold, on the other hand, brings early colour and appears natural and harmonious.With a growth height of approx. 30 to 40 cm the plant is ideal for the foreground to midground. It fits beautifully on pond margins, in damp border beds or areas that are permanently fresh to wet. The recommended planting depth of 0 to –15 cm makes it perfect for the bank and shallow water edge zone: directly in moist soil at the edge or standing slightly in water. Caltha palustris looks particularly attractive when set in small groups – this creates a calm, natural area that visually softens the pond edge.Delivery in a 9-cm pot makes planting easier. If you want a very clear pond margin or want to keep the position flexible, a planting basket is a practical solution: this keeps the marsh marigold stable in the desired place and allows it to be easily moved if necessary.Thanks to winter hardiness zone 1–2, Caltha palustris is suitable for permanently designed pond installations in many regions and is an uncomplicated choice for easy-care, natural pond edge planting.Note on shipping: We make every effort to ensure that our plants arrive healthy and undamaged.

We do not accept any liability for this. Do not plant in open waters such as lakes or biotopes. Zoo-Roco tip: Plant the marsh marigold where you often walk past in spring – it’s a perfect starting point for the pond season. If your water level fluctuates greatly in spring, place the plant in the planting basket at 0 to –15 cm so it stays stable and takes root reliably.

Around ponds, plants are required that are not only attractive during short blooming periods but structure the border zone throughout the whole season. This is exactly where ‘Picta’ comes into its own: The light, colourful-looking foliage brings freshness to the bank zone and forms a beautiful contrast to darker green plants, stones or the water surface.With a height of approx. 60 to 80 cm, ribbon grass is suitable for the middle to background area of pond edge planting. It “frames” the bank line without completely taking away the view into the water, and brings a calm, tidy effect. Phalaris ‘Picta’ appears particularly harmonious when planted in small groups or placed as a recurring element along a pond edge. This creates a natural rhythm that embeds the pond harmoniously.The recommended planting depth of 0 to –15 cm makes the plant ideal for the damp bank zone and very shallow areas. Plant it directly in damp marginal soil or place it in the shallow-water border area – depending on the pond layout. Delivered in a 9-cm pot, ribbon grass can easily be integrated into planting plans, especially if you want to plant several specimens for an even edge effect. For a particularly neat pond edge, a plant basket can be useful to ensure the plant stays stable and so you can simply adjust its position as required.With winter hardiness zone 1, Phalaris ‘Picta’ is suitable for perennial pond installations and is a good choice if you want to combine structure with a bright foliage effect at your garden pond.Note on shipping: We make every effort to ensure that our plants arrive healthy and undamaged. Despite the utmost care, it is possible that plants may be slightly damaged by postal delivery or other unforeseen events. This includes brown leaves as well as bent stems. No liability is accepted for this. Do not plant in open waters such as lakes or biotopes. Zoo-Roco tip: Use Phalaris ‘Picta’ to visually brighten dark corners at the pond edge – for example, next to stones or in front of evergreen plants. If you wish to keep a clear shape, plant the ribbon grass in a plant basket (0 to –15 cm) and cut it back to ground level in spring so that it sends up fresh shoots again.

Especially around ponds, the start of the season is crucial: While many marginal plants are still developing in spring, this primrose already brings colour from March to May (III–V). This makes the pond edge look well-tended and lively early on – ideal if you want your garden pond to be a focal point right from the start of the season.The plant remains pleasantly compact at around 20 to 30 cm in height. This makes it excellent for the foreground of pondside planting, for damp border beds or as a colourful accent between stones and stepping stones. ‘Alba’ looks particularly harmonious when you plant several in small groups: This creates a calm, natural effect and emphasises the shoreline without visually enclosing the water’s surface.The recommended planting depth of 0 to –15 cm gives you flexibility in placement. In practice, the Japanese primrose is ideal in damp bank soil or very shallow marginal areas where the soil remains consistently fresh. The 9 cm pot is perfect if you want to plant several specimens to achieve a visible effect quickly. With fluctuating water levels, a small planting basket can be useful to keep the plant stable and the site tidy.Thanks to Zone 1, Primula japonica ‘Alba’ is winter-hardy and is therefore well suited to perennial pond edge designs. A fitting choice if you want to make your pond edge attractive not only in summer but as early as spring.Note on shipping: We make every effort to ensure our plants arrive healthy and undamaged. Despite the greatest care, it can happen that plants suffer slight damage during postal delivery or other unforeseen events. This includes brown leaves as well as bent or broken stems. We accept no liability for this. Do not plant in open waters such as lakes or biotopes. Zoo-Roco tip: Plant ‘Alba’ where you often pass by in spring – it is ideal for enlivening the pond edge early. If your marginal area becomes temporarily drier in the summer, place the primrose slightly more sheltered in damp soil (rather than deeper into the water) so that it remains evenly supplied.

Salvinia auriculata (Salvinia auriculata)
Salvinia auriculataSalvinia Auriculata (Brazilian salvinia) is a floating plant native to South America. It grows moderately quickly so that its population can be controlled. Easy to grow. Absorbs nitrogen to combat algae. Propagates by spreading.Difficulty of cultivation: easy to mediumLight requirement: medium to highCO₂ requirement: lowHeight of the adult plant: 0.5 cmGrowth: moderate to fastTemperature: 22 - 24°CPlacement in the aquarium: SurfaceOrigin: South and Central AmericaCup diameter 6 cmSalvinia Auriculata (Brazilian Salvinia) is a floating ornamental plant. It is native to the calm, still waters of South and Central America. It can be found from Paraguay to Cuba. It owes its popularity above all to its original appearance. Its small oval leaves with a diameter of 10 mm cm are arranged opposite each other on an elongated leaf stalk. These leaves are covered with fine hairs that trap air bubbles, allowing them to float. Depending on the light intensity, they are wavy or flat. Salvinia forms a third type of underwater leaves on which the spores are deposited.Like all floating plants, Salvinia is recommended for shady waters . Its great appetite for nitrogen and phosphorus compounds makes this plant a good ally in the fight against algae. Salvinia has low light and nutrient requirements. It grows well in both moderate and strong light. As a floating plant, it does not require a substrate but draws all the necessary nutrients directly from the water. During the vegetation period, it reproduces by spreading, whereby the growth rate is moderate. This makes it easy to control its growth and remove excess plants. It grows to a length of 3-6 cm and likes warm, humid air, so it is advisable to use a glass or cover when growing it.It should be placed in such a way that no condensation falls on the plants. It adapts very quickly to the new parameters. However, it should be borne in mind that it will die if there is too little light. It thrives best in soft to medium-hard water at 22-24°C. The in vitro culture of plants is carried out in tissue culture laboratories. Thanks to the sterile production conditions, the cuttings are free from snails, algae or pathogens.Planting:The plant must be removed from the cup and thoroughly rinsed of the gel under running water. This is best done by placing the plant in a container of lukewarm water. Most of the gel will then fall off by itself. Place the plant on the surface of the water.

Lysimachia Nummularia
Lysimachia Nummularia Lysimachia Nummularia is a second level aquarium plant that does well in emersed (above water) form. Easy to grow and tolerant of requirements.Difficult to grow: moderately demandingLight requirements: mediumCO₂ requirements: mediumOutgrown plant height: up to 60 cmGrowth: fastTemperature: 15-26 °Placement in aquarium: Second levelOrigin: EuropeCup diameter: 6 cmLysimachia Nummularia (Sedentary Lysimachia), is an aquatic plant that spreads easily on the bottom when it inhabits the banks of ponds and pools. It has a weakly branched structure. The roots grow in clumps or singly near the round, heart-shaped leaves. If well cared for and not pruned, it can bloom above the surface of the aquarium with yellow flowers.It grows quickly if you provide it with a loamy, sandy substrate along with good light and provide it with enough CO₂ gas fertilizer. Low temperatures don't bother her, but at higher temperatures her growth accelerates considerably, so she can be difficult to control. It prefers soft and slightly acidic water in the aquarium. It feels comfortable at a pH of 6-8. In order to have distinctive, heart-shaped leaves with an intense green color, it requires lots of nitrogen. A nitrogen deficiency will cause the plant to restrict its growth and not climb as much. It is therefore advisable to fertilize it regularly with nitrogenous products and to plant it in aquariums with lots of fish. The hedgehog tree generally grows vertically, without forming too many branches.It grows well in an aquarium with tropical fish, but also in cold biotopes of European waters or on the banks of ponds. Propagation is very simple: just cut the top shoot of the plant and plant it in the substrate, where it will take root. You will achieve the best decorative effect if you plant the plant in small groups of 15-20 specimens. If the shoots are not cut off when it reaches the water table, the plant will continue to grow into an emerse form. Its green-yellow color stands out well against other plants in the aquarium. Lysimachia does well in a hydroponic filter, from which it grows out and forms a green waterfall of leaves that flows into the aquarium. It can also be used in humid terrariums, paludariums or gardens. In a well-lit and regularly sprayed "garden in a jar", it also pleases our eyes with its delicate appearance and rich green color.Planting: The plant must be removed from the cup and thoroughly rinsed from the gel under running water. This is best done by placing the plant in a container of lukewarm water. Most of the gel will then fall off by itself. Divide the contents of the cup into 3-4 cm lumps and then place them in the substrate..

Unlike H. leucocephala and H. tripartita, it grows rather slowly; the water temperature should not be too high. We found magnificent stands in shallow water in the Rio Sucuri, Brazil. The water temperature was 23 °C; the water was crystal clear with a high CO2 concentration. Hydrocotyle verticillata looks very natural in the middle of a Hemianthus carpet, with small ‘umbrellas’ protruding from it.
