Ludwigia inclinata is a striking and versatile aquatic plant popular among aquarists, particularly in planted tanks and aquascaping. It is well known for its vibrant coloration and unique growth patterns, making it a centerpiece in many aquariums.
Overview
- Scientific Name: Ludwigia inclinata
- Common Names: Ludwigia Inclinata, Willow-Leaved Ludwigia
- Family: Onagraceae
- Origin: Central and South America, particularly in regions with slow-moving rivers and lakes.
Appearance
- Coloration: Ludwigia inclinata is renowned for its intense coloration, which can range from green to deep red or orange, depending on the variety, lighting, and nutrient levels. The leaves are typically narrow, elongated, and slightly twisted, giving the plant a unique appearance.
- Size: This plant can grow quite tall, reaching up to 30-50 cm (12-20 inches) in height, depending on the conditions. The stems are usually thin and may require regular trimming to prevent them from becoming too tall.
Varieties
- Ludwigia inclinata var. verticillata: This variety is particularly popular for its intense red coloration, especially under high light and CO2-enriched conditions.
- Ludwigia inclinata 'Cuba': Known for its more orange-yellow hues and twisted leaf appearance, making it distinct from other varieties.
Habitat and Tank Requirements
- Tank Size: Ludwigia inclinata can be grown in tanks of various sizes, though larger tanks are preferable due to the plant's height and spreading nature.

Water Parameters:
- Temperature: 22-28°C (72-82°F)
- pH: 6.0-7.5
- Hardness: Soft to moderately hard water (2-12 dGH)
- Lighting: High lighting is essential for this plant to develop its vibrant colors. Under low light, the plant may grow leggy, and the colors will be less intense.
- CO2: Supplemental CO2 is highly recommended to encourage healthy growth and maintain the vibrant coloration. Without CO2, the plant may still grow but will not reach its full potential in terms of size and color.
Growth and Maintenance
- Growth Rate: Ludwigia inclinata has a moderate to fast growth rate, especially under high light and CO2 conditions. It tends to grow vertically, so regular trimming is necessary to maintain its shape and encourage bushier growth.
- Propagation: This plant is easy to propagate through cuttings. Simply cut the top portion of a healthy stem and replant it in the substrate. The parent plant will often sprout new side shoots, promoting a bushier appearance.
- Maintenance: Regular trimming is required to keep the plant manageable and encourage fuller growth. The plant can become leggy if not maintained properly, so cutting and replanting the tops is recommended.
