Common Name: Ludwigia Arcuata (Needle leaf ludwigia)
Family Name: Onagraceae
Origin: North America
Ludwigia Arcuata is a beautiful plant with delicate green and red leaves. This is an easy plant to keep that adds movement and dimension to the aquarium. Needle leaf plants have thin, pointed leaves that grow in opposite pairs along the whole length of the stem. The leaves can be green or red depending on the amount of iron available in the water. If pruned frequently, this plant will branch out and provide a bushy filler for the mid- or background of your tank.
Ludwigia Arcuata is a versatile plant, but to get the desirable bright red color, you must provide high lighting and nutrient levels. High iron content will bring out more red tones in the plant. CO2 injection is not required for the cultivation of this plant but can help it grow more robustly. The plant can be grown submersed or emersed.
When grown emersed, the leaves tend to be round like other types of Ludwigia and remain green. When grown under high light and submerged in an aquarium, the leaves turn thin and orange to red depending on nutrients. Dosing UNS Plant and iron supplements will bring out the deep red coloration.
Propagation can be achieved by taking cuttings from the main stem of the plant that are replanted into the substrate.
