General Description
The Ludwigia repens, commonly known as Creeping primrose-willow, is a classical aquarium plant that is native to the southern regions of the United States, Central America, and the Caribbean. In its natural habitat, it thrives on the edges of various waterbodies such as ditches, rivers, lakes, and ponds, often forming dense trailing populations with shoot tips extending over the water surface. This species displays high variability and easily hybridizes with other Ludwigia species, posing challenges for scientific identification of local forms.
Aquarium Suitability
Ludwigia repens is a highly popular aquarium plant worldwide due to its ease of care and vibrant appearance. It is readily available commercially and from other aquarists, making it easily accessible for aquarists of all levels. With a fast growth rate and minimal demands, it is suitable for a wide range of aquarium setups.
Demands and Hardiness
Ludwigia repens is an easy-to-care-for plant that thrives under relatively low light conditions, requiring only 0.4 watts per liter and no CO2 fertilization. To enhance its reddish coloration, providing sufficient light (0.5 watts per liter or above) and maintaining optimal nutrient levels, such as low levels of NO3 and high phosphate content, is recommended. Propagation is simple through cuttings, where lateral or top shoots can be replanted in the substrate.
Aquascaping & Usage
Versatile in aquascaping, Ludwigia repens can be used to set red accents in the middle or background of the aquarium. It can also serve as a foreground plant in larger setups, provided it is regularly trimmed to maintain its desired appearance. Its trailing growth habit adds dynamic visual interest to aquascape designs.
Propagation
Propagation of Ludwigia repens is straightforward, involving the cutting and replanting of lateral or top shoots in the substrate. New growth emerges quickly, forming lateral shoots that contribute to the plant's lush appearance. Regular pruning helps control its growth and shape within the aquarium environment.
Habitat and Distribution
In its natural habitat, Ludwigia repens can be found in the southern United States, Central America, and the Caribbean. It typically thrives on the margins of water bodies, where it forms dense populations and extends its shoot tips over the water surface. The species' adaptability to various aquatic environments contributes to its widespread distribution in both the wild and aquarium trade.
