General Description
Ludwigia palustris is a highly variable species commonly known as Marsh seedbox, widely distributed in boggy habitats globally. Initially not native to Australasia, it has been introduced to the region. This plant exhibits a versatile growth pattern, thriving in both submerged and emerged states in shallow ponds and slow-flowing waters. It has been popularly utilized in the aquarium hobby under various names such as "Red Ludwigia" or "L. mullertii," although true L. palustris is sometimes mislabeled.
Aquarium Suitability
This plant is considered suitable for aquariums, as it is compatible with various water conditions and relatively easy to care for. It requires ample light for optimal growth but can survive in moderate lighting as well. While additional macronutrients like NO3 and PO4 can benefit its growth, they are not mandatory. CO2 injection and micronutrient fertilization are optional, but they contribute to the plant's vibrancy.
Demands and Hardiness
According to the provided information (see table), L. palustris prefers medium to high lighting levels, temperatures between 22-26°C, and a pH range of 5-8. It shows flexibility in temperature tolerance, thriving in environments from 4-28°C. The plant can adapt well to different water conditions and substrates, making it a robust choice for aquariums.
Aquascaping & Usage
In aquascaping, L. palustris serves as a vibrant accent plant, particularly the reddish variety, adding a pop of color to the midground or background of the tank. Its fast growth rate and colorful foliage make it an attractive choice for creating visually appealing aquatic landscapes. Combining it with plants of contrasting textures and shades enhances its aesthetic appeal.
Propagation
Propagation of L. palustris involves straightforward methods common to stem plants; lateral or top shoots can be cut and replanted in the substrate to encourage new growth. Removing the top shoot prompts the remaining stem to produce lateral shoots when left in the aquarium, facilitating the plant's propagation and expansion within the tank.
Habitat and Distribution
Natural habitat: Ludwigia palustris is found in a range of wetland habitats globally, with a propensity for shallow ponds and slow-flowing waters. It is highly adaptable to diverse environments and is even cultivated in garden ponds or containers. The plant's distinctive flower structure, featuring four green calyx tips and four yellow stamina without petals, aids in its identification.
