🌱 What is Ludwigia?
Ludwigia is a genus of fast-growing aquatic plants that occur in both emersed and submerged forms. The plants originate from North and South America and thrive in tropical aquariums. Depending on the species and the conditions, the leaves can range in color from light green to bright red.
🌿 Popular Ludwigia Varieties
| Kind | Colour | Height | Difficulty level |
|---|---|---|---|
| Ludwigia Repens Mini Super Red | Intense red, compact | 10–20 cm | Average |
| Ludwigia Repens Diamond Red | Deep red with shine | 20–40 cm | Average |

💧 Care & Growth
- Light: Moderate to strong (for color development)
- Temperature: 20–28°C
- pH: 6.0–7.5
- CO₂: Recommended for strong color and compact growth
- Nutrition: Root tablets + liquid fertilizer (iron-rich)
With sufficient light and CO₂, Ludwigia develops intense colors. Without these conditions, the plant may remain green or grow elongated.
✂️ Pruning & Propagation
Ludwigia is easy to prune and propagate:
- Prune the top above a leaf node to encourage new side branches
- Replant the cut tops in the soil
- Regular pruning prevents the plant from becoming too long and bare at the bottom
🎨 Aquascaping Applications
Ludwigia adds color and structure to the center and background of the aquarium. Its upright growth makes it ideal for Dutch-style aquariums and as an accent in nature-style layouts.
- Position: Mid to background
- Combine with: Green plants such as Hygrophila, Limnophila and Java fern
- Contrast: Against Anubias or mosses for visual depth
