Echinodorus cordifolius ‘Marble Queen’, AKA Marble Queen Sword, is a large aquatic plant known for its marbled leaves. Its primary light-green color displays a mix of green and cream tones to add pops of contrast and texture to planted aquariums.

Like other Echinodorus, this plant will grow large over time, making it best for larger aquariums, ponds, or open-top setups where it has room to spread out and fully develop. As it matures, it can easily become a focal species or centerpiece plant.

Marble Queen is relatively easy to care for and adapts well to a range of aquarium conditions, making it an ideal introductory aquatic plant. It prefers nutritious substrate and benefits from regular root feeding due to its extensive root system.

It's worth it to note that Sword plants produce large leaves and can shade surrounding plants if left untrimmed. Overall, Echinodorus cordifolius ‘Marble Queen’ is a hardy, statement aquarium plant that adds vibrant foliage and natural coverage to larger planted aquariums.

About Our Live Aquatic Plants

Aquarium plants can vary in growth form and may require time to transition to your aquarium environment, whether grown submerged or emersed. This transition period is a natural part of establishing healthy, long-term growth in planted aquariums.

From carpeting plants in the foreground to stem plants and larger species used in the midground or background, each plant offers a unique contribution to a balanced and natural aquascape. As plants adapt, it is normal to see minor changes such as leaf melt, color shifts, or new growth patterns as they settle into their new conditions.

We carefully inspect and prepare all live aquatic plants prior to shipping. While we do our best to minimize hitchhikers, we cannot guarantee plants to be completely pest or snail-free unless tissue culture options are selected.

Because live plants are perishable, some signs of transit stress may occur, including leaf loss or cosmetic damage. These are typically temporary and when when healthy roots are present, most plants will recover with proper care.

About Our Tissue Culture Plants

Tissue culture aquarium plants are grown in sterile, laboratory conditions, ensuring they are free from pests, algae, and snails. These young plants are cultivated in nutrient-rich gel and are grown in emersed form before being introduced into the aquarium.

Tissue culture plants are best for aquascapers looking for clean, controlled plant material, especially for shrimp tanks or sensitive setups. Before planting, the gel media should be gently removed, and the plant can be divided into smaller portions for planting.

With proper care, tissue culture plants transition quickly and establish into healthy submerged growth.
