Lagenandra meeboldii 'Silver Queen' is a striking aquatic plant known for its silvery-green leaves and unique appearance. This plant, when cultivated through tissue culture, offers a pest-free, disease-free, and algae-free option for aquarists looking to add a touch of elegance to their aquascapes. Here’s a detailed overview:

Description

• Appearance: Lagenandra meeboldii 'Silver Queen' is characterized by its broad, lanceolate leaves that are a silvery-green color, sometimes with a hint of purple on the undersides. The leaves have a slightly wavy edge and a smooth texture, making them stand out in the aquarium. The plant's overall appearance is similar to that of Cryptocoryne species, but it is distinguished by its larger size and the unique coloration of its leaves.
• Size: 'Silver Queen' can grow to a height of 20-40 cm (8-16 inches) with a spread of about 15-30 cm (6-12 inches), making it suitable for midground or background placement in medium to large aquariums.

Habitat

• Native Range: Lagenandra species are native to India and Sri Lanka, where they typically grow in shaded, slow-moving waters, similar to the natural habitats of Cryptocoryne species.
• Natural Habitat: In the wild, these plants are found in humid, tropical environments, often growing partially submerged along the edges of rivers and streams.

Care and Maintenance in Aquariums

• Tank Size: Due to its potential size, Lagenandra meeboldii 'Silver Queen' is best suited for medium to large aquariums, where it can be placed in the midground or background.
• Water Parameters: This plant thrives in tropical aquariums with temperatures ranging from 22-28°C (72-82°F) and a pH level between 6.0 and 7.5. It prefers soft to moderately hard water but is quite adaptable to various water conditions.
• Substrate: A nutrient-rich substrate is essential for Lagenandra meeboldii 'Silver Queen' to develop strong roots and maintain its vibrant coloration. Aquasoils or substrates designed for planted aquariums work best.
• Tank Setup: This plant prefers moderate to low light conditions, similar to its natural, shaded habitat. High light can cause the leaves to fade in color or encourage algae growth. CO2 supplementation is not strictly necessary but can enhance the plant’s growth and vitality, especially in a high-tech setup. Regular dosing with liquid fertilizers, particularly those rich in iron, will help maintain the plant’s striking coloration.
