Echinodorus arjuna

Echinodorus arjuna is a bold and eye-catching Amazonian sword plant, celebrated for its green to reddish-brown leaves that turn redder in high light conditions, the interesting thing about this plant is that all the leaves can be slightly different colours based on age. Native to South America, it forms upright, lance-shaped foliage that adds striking colour and structure to midground or background areas.
Its vibrant, warm-toned leaves create a focal point in any aquascape, making it a versatile choice for nature-style, jungle-style, or biotope aquariums.

How to Use in the Aquarium

This plant is perfect for midground to background placement, where its dramatic red foliage can contrast with green carpets or stems.It works well in combination with other Amazonian plants like Echinodorus species, Cryptocoryne, and Helanthium, or alongside dark hardscape materials such as driftwood and rocks.
Plant a few specimens together to form a lush, bold grouping that naturally draws the eye.

Maintenance

Echinodorus arjuna is hardy and moderately easy to maintain, but performs best under moderate to high light to maintain its red tones.

• CO₂: Optional, but encourages faster growth and more vivid coloration

• Substrate: Nutrient-rich substrate recommended for strong root development, root tab regularly

• Occasional trimming of older leaves will encourage fresh growth and preserve its compact, structured form.

Emersed Growth

This variety thrives emersed as well, retaining its warm red tones above water. It can produce thicker, stronger leaves and even small white flowers in paludariums or shallow tropical setups. Its dramatic color and upright form make it an attractive focal plant both in aquariums and emersed displays.
