TCulture Ludwigia Arcuata (TC Cup)
Common Name: Needle Leaf Ludwigia
Needle leaf ludwigia 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.
Needle leaf 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.
Notes:

Ludwigia can be very fragile. Be sure to handle this aquarium plant with care.
Do not make drastic changes to the aquarium. Unstable parameters will result in melt and rotting of the aquarium plant.

Remove the cotton surrounding the roots and plant into a quality substrate. For instructions on how to properly prep aquarium plants, click here.

CO2 injection and quality aquarium soil will yield better growth.
Please research appropriately to ensure your plant thrives.

Ludwigia Arcuata in Singapore Planted Tanks

Ludwigia arcuata, the needle-leaf ludwigia, is a fine-textured red stem prized for the delicate, narrow foliage that sets it apart from broader-leaved Ludwigia species. Used as a midground accent or massed for a softer background, it brings warm orange-to-red tones that contrast beautifully against green carpets and mosses. The tissue-culture cup is the cleaner choice for a new scape, arriving free of snails and algae, while the potted form gives you more established mass straight away.

Colour intensity follows light and nutrients here, not luck. Brighter LED output, steady CO2 and lean nitrate push it red; under modest light it stays a pleasant lime-green. Our 27-29C ambient sits comfortably within its range, though warmth speeds growth, so expect to trim and replant tops regularly to keep a dense, bushy shape rather than thin straggly stems reaching for the surface.
