Ludwigia Arcuata - Don Not Use, Needle Leaf
Ludwigia arcuata (Needle Leaf)
Ludwigia arcuata is a rare narrow-leaved North American red plant producing exceptionally fine, needle-like leaves on arching stems that develop warm red hues under strong light and CO₂. As an advanced plant requiring both CO₂ and strong light to thrive, it provides a type of fine-textured red color quite unlike the broader-leaved Ludwigia species when conditions are properly met. Can grow both emersed and submerged, adding paludarium utility to its aquarium applications.
Care tip: Ludwigia arcuata (Needle Leaf) grows best in moderate lighting with CO₂ required. Maintain temperatures of 72–82°F and pH 5.5–7.5. Regular liquid fertilization supports healthy growth and best coloration.
Growing to 12 to 20 inches under aquarium conditions, arcuata requires high-light, CO₂-enriched conditions for healthy, colorful growth. The needle-like leaves are most finely expressed in well-maintained plants with stable water chemistry. Regular trimming maintains compact growth and the fine-textured, arching stem habit that distinguishes arcuata from other narrow-leaved Ludwigia forms.
As an advanced plant, Ludwigia arcuata requires CO₂ injection and is listed as requiring both strong light and CO₂ in its care requirements. Temperatures between 72 and 82°F and a wide pH range of 5.5 to 7.5 provide flexible water chemistry conditions. Consistent fertilization supports the needle leaf production and the red coloration under strong light.
In the aquascape, Ludwigia arcuata creates fine-textured red background coverage whose arching, needle-leaved stems create a delicate, graceful quality different from the more upright needle-leaved forms. It is most effective in high-tech aquascapes where the narrow red leaves can be properly developed and maintained.
Ludwigia arcuata is an advanced narrow-leaved red plant for high-tech aquarists seeking fine-textured warm color from a botanically authentic North American species.
