Echinodorus cordifolius ‘Marble Queen’: A Stunning Variegated Sword Plant for Freshwater Aquariums
Description:
Echinodorus cordifolius ‘Marble Queen’ is a beautiful variegated variety of the classic Heartleaf Sword Plant, prized for its unique marbled leaves that feature striking green and creamy white patterns. This eye-catching plant adds a splash of brightness and texture to midground or background areas in freshwater aquariums, making it an excellent choice for aquascapers seeking contrast and natural elegance.
Like its parent species, Echinodorus cordifolius ‘Marble Queen’ produces broad, heart-shaped leaves that can grow up to 18 inches tall, providing excellent coverage and shelter for fish and invertebrates. The marbled coloration is enhanced under moderate to high lighting and nutrient-rich substrate, with leaf patterns becoming more vivid with good care.
This plant is hardy and adaptable, thriving in a wide range of water conditions. It grows quickly when supplied with root tabs or an enriched substrate and can benefit from CO₂ supplementation for even more vigorous growth. Flower stalks may appear above the water’s surface, occasionally producing baby plants for propagation.
