Ludwigia repens thrives in aquariums with moderate lighting, though higher light levels bring out its reddish hues, especially on the undersides of its leaves. While it can grow in low-tech setups, adding CO2 and liquid fertilizers will boost its growth and enhance its coloration.

Planting it in nutrient-rich substrate or using root tabs ensures robust root development and overall health.

This plant is an excellent choice for midground or background placement, creating vibrant contrasts with green plants or hardscape elements. Its vibrant color intensifies under ideal conditions, making it a stunning addition to aquascapes. Ludwigia repens can also grow emersed, making it suitable for paludariums or ripariums.
