Ludwigia inclinata 'Dark Orange'

Ludwigia inclinata ‘Dark Orange’ — Intense Warm Colour for the High-Tech Aquascape

Ludwigia inclinata ‘Dark Orange’ is a stunning cultivar of one of the most spectacular stem plants in the planted aquarium hobby, selected for its exceptionally rich, deep orange colouration that develops under high light and optimal nutrient conditions. With its narrow, lance-shaped leaves arranged in whorls along tall, upright stems, this variety brings a blazing column of warm, fiery colour to the midground and background of any high-tech aquascape — one of the most visually impactful red-orange stem plants available.

Deep, Blazing Orange — Unlike Any Other Ludwigia

Ludwigia inclinata is already celebrated for its extraordinary colour range across its various forms, and the ‘Dark Orange’ cultivar represents one of the most intense and saturated expressions of warm orange achievable in a submerged stem plant. Under strong light, CO₂ injection, and consistent macro and micronutrient dosing, the upper leaves develop a deep, burnished orange that glows under aquarium lighting — creating a dramatic focal point that anchors the warmth and colour palette of the entire aquascape.

Care Profile

• Scientific Name: Ludwigia inclinata ‘Dark Orange’
• Origin: Cultivar; species native to South America
• Type: Stem plant (whorled)
• Growth Rate: Moderate to fast under optimal conditions
• Height: 20–50+ cm
• Placement: Midground to background; most effective planted in groups of 3–5 stems
• Light: High — intense light is essential for deep orange colouration; insufficient light results in pale orange or greenish growth
• CO₂: Strongly recommended — CO₂ injection is critical for achieving and maintaining peak colour intensity and growth rate
• Fertilisation: Regular macro and micronutrient dosing required; iron and potassium supplementation particularly beneficial for colour development
• Water Temperature: 22–28°C
• pH: 5.5–7.0 (soft, slightly acidic water produces the best colour)
• Propagation: Stem cuttings — trim tops and replant; side shoots will develop from lower nodes
• Note: A demanding species that performs best in high-tech setups with CO₂, strong light, and consistent fertilisation. Not recommended for low-tech aquariums.

Aquascape Compatibility

Ludwigia inclinata ‘Dark Orange’ is a striking choice for Nature Aquarium and Dutch-style aquascapes where bold, warm colour is a design priority. It pairs beautifully with green stem plants — Rotala rotundifolia, Limnophila, and Eleocharis — as well as red species such as Rotala macrandra and Alternanthera reineckii for a rich, multi-tonal warm colour palette. Its whorled leaf arrangement also provides a distinctive textural contrast to fine-leaved or broad-leaved neighbours.

Blazing, intense, and unmistakably dramatic — Ludwigia inclinata ‘Dark Orange’ is the fiery focal point that sets the colour standard in the high-tech planted aquarium.
