LUDWIGIA ARCUATA – Fine-Leaved Red Stem Plant for High-Light Aquariums
Ludwigia arcuata is a fine-leaved aquatic stem plant admired for its narrow foliage and vibrant coloration, which ranges from copper-brown to vivid red depending on light intensity. Native to the wetland areas of North America, this species brings a refined vertical element to the middle ground of planted aquariums, offering structure, color and a natural aesthetic appeal. Its delicate form and environmental responsiveness make it a favorite among experienced aquascapers.
In emersed form, the stems remain green, but when submerged, the plant develops warmer hues, making it ideal for nature-style layouts and Dutch aquariums. It grows rapidly under strong lighting and responds well to CO₂ supplementation. Ludwigia arcuata propagates easily through head cuttings and side shoots, and trimming the lower third of its stems encourages dense branching and healthy new growth.
