Ludwigia Sedoides is also known as “Mosaic Plant”, “Mosaic Flower”, or “False Loosestrife” which is an aquatic plant species belonging to the Onagraceae family. The natural habitat of this plant is South and Central America. It is common in Brazil and Venezuela. Rivers with weak currents and swampy soils are natural habitats of this plant. It is a plant that is generally suitable for ponds and preferred there. So, it is challenging to grow this plant in an aquarium. It has also behaved invasively in some areas.

Ludwigia Sedoides can grow to a diameter of 10-15 cm. Its leaves can have many different colors, such as green, red, yellow, gold and pink. These leaves are diamond-shaped and, when gathered together, form a mosaic image. For this reason, it is also called the Mosaic Plant. The leaves and flowers of this plant are on the water surface and, the roots are in the water. It has distinctive yellow and golden flowers that bloom between June and August.


The most significant point to be considered in growing this plant is light. Unlike most aquarium plants, it has a high light requirement. Sometimes even high-intensity lighting may be insufficient. It should receive direct and long-term sunlight. Ludwigia Sedoides grows well in waters with a pH range of 6-8. It cannot tolerate water with a pH level above 8. The best to cultivate Ludwigia Sedoides in waters between 21-24 degrees. On the other hand, it can tolerate water temperature up to 34 degrees Celcius, according to some sources. It is suitable for growing in waters with a carbonate hardness of 2-15. The addition of carbon dioxide is not necessary for the growth. But it also needs intensive fertilization and macro-micro nutrients for growing.

Ludwigia Sedoides is fragile and sudden changes in water parameters can damage or even kill the plant. Since it lives in slow-flowing or stable waters in its natural environment, the aquarium or pond conditions should be adjusted accordingly. Creating a strong current is a factor that can damage the plant. Flowering occurs if the optimum conditions are provided for the plant.

Ludwigia Sedoides is so easy to propagate. A root with a rosette should be identified. Then this part is cut and separated from the main part. The cut part begins to grow spontaneously.


In summary, it is not common to grow this plant in aquariums. The biggest reason for this is the intense light requirement. For this reason, it is more preferred in ponds than aquariums. When the light conditions are provided, it is not that difficult to meet other parameters. It can survive in parameters similar to other floating plants. If it is to be grown in an aquarium, some situations need attention. The most important of these is the size and density of its leaves, which can prevent light from reaching the bottom of the aquarium. On the other hand, because it can easily reproduce and sometimes behave invasively, it can cover the water surface in the aquarium. This can damage the bottom plants that live together in the aquarium and need light. When such situations are encountered, the problem can be solved by removing some portions out from the aquarium.
