Expanded Light Requirements:
For Ludwigia glandulosa, achieving vibrant colouration and healthy growth requires high-lighting conditions. The plant thrives under a PAR (Photosynthetically Active Radiation) value of 50-70, considered high light intensity in the aquarium hobby. This light level encourages the red and purple hues for which Ludwigia glandulosa is celebrated.
The ideal Kelvin range for the lighting should be between 5000 and 7000. This spectrum supports photosynthesis efficiently while enhancing the natural colours of the plant. Lights closer to 5000 Kelvin will emphasize the green hues in plants, while those closer to 7000 Kelvin enhance reds and purples, making them preferable for Ludwigia glandulosa.
LUX, or the measure of light intensity as perceived by the human eye, should be 30-50 LUX for Ludwigia glandulosa. However, it’s important to note that LUX is not as relevant to plant growth as PAR, which explicitly measures the wavelengths used by plants for photosynthesis.

Origins And Habitat
Ludwigia glandulosa is native to the southeast United States and can be found in wetland areas and roadside ditches throughout most southern states. It thrives in warm temperatures and requires ample light to survive. The perennial plant can grow to a maximum height of about 40 cm. Ludwigia glandulosa benefits from the presence of phosphates and nitrates in the water. It is a threatened species in Indiana and endangered in Maryland, requiring special precautions to protect it from invasive species and human activities.
Morphological Characteristics
Ludwigia glandulosa is a beautiful perennial herb/forb plant that can add a touch of vibrant colour to any aquascape. It grows up to a foot and six inches in height, making it an excellent choice for small and large aquariums. The plant features oval, pointed leaves that grow in opposite pairs along the stem. With adequate lighting, these leaves can display a stunning range of colours, from green and gold to orange and red.
Ludwigia glandulosa is a versatile plant that can be grown submerged or emersed, depending on your desired aesthetic. It can create an eye-catching focal point with its unique foliage when placed in an aquarium. The plant prefers a slightly acidic to neutral pH level, ranging from 6 to 7.5, to thrive and flourish.
Propagation of Ludwigia glandulosa can be easily accomplished by taking cuttings from the main stem. These cuttings can then be replanted in the substrate, enabling new plants to grow and expand your aquascape.
Placement And Lighting
Ludwigia glandulosa is a versatile aquatic plant that can be used as both a mid-ground and background plant in aquariums. Planting in bunches of 10-12 stems creates a visually appealing focal point in the aquascape.
High lighting and nutrient levels are essential to achieve the vibrant and desirable red colours of Ludwigia glandulosa. The plant requires intense light to maintain its vibrant red hue. Additionally, supplementing the aquarium water with iron can enhance the red tones of the plant, making it even more visually striking.
CO2 injection is highly recommended for optimal growth and colouration of Ludwigia glandulosa. A steady supply of CO2 encourages healthy and robust growth, leading to more luscious foliage and brighter colours. CO2 supplementation can be achieved using various systems, such as pressurized CO2 setups or do-it-yourself (DIY) CO2 fermentation.
Ludwigia glandulosa can be grown either fully submerged or partially emerged. When fully submerged, the plant thrives underwater, with its vibrant red colours against green foliage. On the other hand, partially emersed Ludwigia glandulosa can produce delicate yellow flowers, adding an extra touch of beauty to the aquarium.
What Are Good Tank Mates?
Ludwigia glandulosa can thrive alongside various fish species and aquatic plants in your aquascape. When selecting tank mates for Ludwigia glandulosa, it is essential to consider their compatibility and impact on the plant’s well-being. Choosing suitable tank mates allows you to create a harmonious and visually appealing aquarium environment.
Good Tank Mates
The following fish species are known to be good tank mates for Ludwigia glandulosa:
- Tetras

These small and peaceful fish species share similar water parameters and can coexist peacefully with Ludwigia glandulosa. Their active swimming patterns and vibrant colours can provide a pleasing contrast to the plant’s rich red hues, enhancing the overall visual appeal of your aquascape.
Fish Species To Avoid
While many fish species can coexist with Ludwigia glandulosa, there are a few to avoid due to their potential to uproot or damage the plant. It is best to steer clear of the following fish species:
- Cichlids
- Large bottom-dwelling fish
Cichlids are known for their digging behaviour, which can uproot the delicate roots of Ludwigia glandulosa. Large bottom-dwelling fish, such as plecos, may unintentionally damage the plant while searching for food. Additionally, aggressive fish or those prone to fin-nipping should be avoided to prevent any harm to the plant’s foliage.
To maintain the health and beauty of Ludwigia glandulosa in your aquascape, it is essential to consider these compatible and incompatible fish species when planning your aquarium community.
Feeding (Fertilization)
Ludwigia glandulosa, like many other aquatic plants, requires regular fertilization to ensure healthy growth and vibrant colouration. By providing the plant with the necessary nutrients, you can help it thrive in your aquarium. A balanced plant fertilizer that contains essential elements such as nitrogen, phosphorus, and potassium is recommended for Ludwigia glandulosa. These nutrients are crucial for its overall health and vitality.
Regarding the frequency of fertilization, it depends on your specific fertiliser. As a general guideline, feeding Ludwigia glandulosa once or twice weekly is usually sufficient. However, it is essential to follow the instructions provided by the fertilizer manufacturer and adjust the dosage according to the size of your aquarium. Over-fertilizing can lead to algae problems and other imbalances within the tank, so finding the right balance is crucial.
In addition to regular fertilization, performing regular water changes can help maintain optimal nutrient levels for Ludwigia glandulosa. Water changes help remove accumulated waste or excess nutrients that may harm the plant’s health. Aim for consistent and balanced nutrient levels to support the growth and colouration of Ludwigia glandulosa in your aquarium.
