Echinodorus 'Marble Queen'

🌿 Echinodorus 'Marble Queen'

Echinodorus 'Marble Queen', commonly known as Marble Queen Radican Sword, is a striking sword plant selection famous for its bold, creamy-white and pale yellow marbling splashed across broad emerald-green leaves. Its dramatic variegated foliage makes it an eye-catching centerpiece plant for both medium and large aquariums.

🌱 Growth & Appearance

This species produces broad, heart-shaped to ovate leaves that sprout outward from a central crown base. The leaves display distinct creamy-white variegated splotches and marbling, giving each leaf a unique mosaic pattern.

It grows at a steady pace, developing a large, sturdy rosette. Under submerged conditions, it stays somewhat more compact, though under high light or shallow water, it may send up tall emergent leaves that lift above the waterline.

💡 Lighting & CO₂

Echinodorus 'Marble Queen' requires moderate to high lighting to maintain crisp, vibrant variegation. Under weak illumination, the creamy-white marbling can fade, causing newly emerging leaves to turn a solid, uniform green.

CO₂ injection is optional, making it a reliable variegated plant for low-tech setups. However, as a heavy root feeder, it requires a nutrient-rich substrate and benefits significantly from regular root tab supplementation rich in iron and key micro-nutrients.

🪴 Planting & Maintenance

Plant the root base into a deep, nutrient-dense substrate, making sure the growing crown remains slightly above the soil line to prevent rotting. Position it in a permanent spot, as its extensive root network dislikes frequent transplantation.

To keep the plant compact and fully submerged, prune away tall petioles reaching for the surface near the base of the crown. Propagation is straightforward via adventitious plantlets that form along flower stalks on mature, healthy specimens.

🌿 Best Use

Echinodorus 'Marble Queen' makes a magnificent midground to background centerpiece plant for nature aquascapes, community aquariums, and large display tanks.

Its bright variegated leaves create exceptional visual contrast against dark hardscapes, fine-leaved background stems, and uniform green carpets.
