Canton Aquatics Ludwigia Repens Dark Red — Bare Root Stem Plant
Best for creating a dramatic vertical backdrop, Ludwigia Repens Dark Red displays deep red to burgundy foliage under medium to high light. The plant is easy to grow, tolerating a wide temperature range and does not require CO2 injection, though supplementing CO2 will enhance color and growth. It typically reaches 12-20 inches tall, making it an excellent background specimen and a fast-growing filler for bare spots.
Who it’s best for: Beginners seeking a striking red background and aquarists who want a low-maintenance stem plant with strong color under typical home-tank lighting.
Why selected: This variety combines vibrant color with a broad light tolerance and a rapid growth rate, helping to quickly fill vertical space and reduce leggy stems.
Caution: Color intensifies with strong lighting and nutrients; under low light, red tones can fade or become less vivid.
Notes: Medium light is sufficient; CO2 is optional but beneficial for color depth and bushier growth.

Buying Guide: Red Stem Plants For Aquariums
What should I consider when buying red stem plants?
- Lighting: Red hues typically intensify under medium to high light. If your tank has low light, you may still enjoy color but expect less saturation.
- Height and placement: Use tall stems like Ludwigia Repens for backgrounds and shorter varieties for foreground accents to create depth.
- Growth rate: Fast-growing stems help fill space quickly but may require regular trimming to maintain shape and color.
- CO2 and nutrients: CO2 is optional for many red stems but can significantly improve color depth and growth when added. Balanced nutrients support vibrant foliage.
- Tank mates: Consider compatibility with your fish and invertebrates since some plants may require time to establish before high-energy tank residents populate the area.
- Water parameters: Most red stems favor typical tropical freshwater ranges; verify any species-specific temperature or pH preferences before planting.
