Rotala sp. Araguaia Red Cross

Plant Profile

Rotala sp. 'Araguaia Red Cross' (commonly known as Rotala Red Cross) is a rare, newly introduced aquatic stem plant native to the tropical waterways of Vietnam. Highly sought after by plant collectors and high-tech aquascapers, this exquisite species is characterized by its thin, spiky leaves radiating from supple, ascending stems. Under high-tech conditions, it displays a breathtaking color gradient, shifting from soft green at the lower stem to warm yellow and vibrant golden-orange toward the upper tips.

Key Features & Benefits

• Thin, spiky foliage displays an eye-catching gradient from soft green to warm yellow and fiery orange tips.
• Rare collector stem species that creates a striking visual centerpiece against broad-leaved green plants.
• Ascending stem habit easily branches into dense, colorful bushes when properly pruned.

Care & Planting Instructions

• Remove lead weight and remove cotton wrap (or foam) surrounding the base, then strip the lower inch of foliage so bare stems anchor cleanly into soil without rotting. *Rotala has fragile leaves, so handle stems with care during preparation.
  
• Use fine-tip pinsettes to push individual stems 1 to 2 inches into substrate, spacing them slightly apart so light reaches lower growth.
  
• Provide high-intensity lighting and pressurized CO2 injection; consistent fertilization with a specialized liquid macro and micro formula yields robust growth and deep orange-red leaf tips. See our guide to growing red aquarium plants.
• Maintain soft, slightly acidic water conditions and stable parameters to prevent stem melting or leaf shedding.
• To propagate, trim healthy stem tops or side shoots with sharp straight scissors and replant them directly into the substrate. Read our trimming & propagation guide for details.

Frequently Asked Questions

1. Why are the lower leaves falling off my stem plants?

Lower leaf loss (leggy stems) usually occurs when lighting cannot reach the bottom of the plant due to overcrowding or shading from larger plants. Spacing individual stems slightly apart during initial planting and maintaining strong light penetration will keep lower leaves healthy.

2. How do I get the most vibrant orange and red colors on Rotala Red Cross?

Achieving vivid orange and red leaf tips requires high-intensity lighting, pressurized CO2, a nutrient-dense aquasoil, and balanced liquid fertilization supplying iron and essential trace elements.

3. Can Rotala sp. Araguaia Red Cross be grown emersed?

Yes, Rotala Red Cross can be grown in emersed conditions in high-humidity setups like terrariums or paludariums, though its leaves will transition to a green, compact terrestrial form until submerged again.
