Common Names

Lagenandra ovata

Origin

Lagenandra ovata originates from Sri Lanka, where it thrives in the tropical wetlands, marshes, and riverbanks. In its natural habitat, it experiences both submerged and emerged conditions due to fluctuating water levels, making it highly adaptable for use in aquariums and paludariums.

Quick Overview

• Ideal For: Aquariums, paludariums
• Difficulty Level: Medium
• Lighting: Medium

Growing Conditions

Lagenandra ovata is a versatile plant that can grow both submerged and emerged. It performs well in aquariums when fully submerged but can also thrive in paludariums or humid environments where it grows emerged. This plant is known for its adaptability, tolerating a range of water parameters. It prefers slightly acidic to neutral pH levels of 6.5 to 7.2, with a water hardness range of 0 - 18 dGH. For optimal growth, plant it in fine gravel substrate, which supports its rhizome and root system. It requires medium lighting, which helps it maintain healthy growth without the risk of algae overgrowth that can occur with stronger light intensities.

Planting Area

Due to its potential size, reaching up to 90 cm (35.43 inches) in height, Lagenandra ovata is ideal for placement in the background of larger aquariums. Its tall, lush foliage creates an impressive backdrop, adding depth and texture to aquascapes. When grown in paludariums or semi-aquatic setups, it adds a striking vertical element to the landscape. Ensure there is enough space around the plant to allow for its full development.

Propagation

Lagenandra ovata reproduces through runners, producing young plantlets that develop roots over time. Once the plantlets have established their root system, they can be separated from the mother plant and replanted elsewhere in the tank. It can also be propagated by dividing the rhizome, ensuring that each divided section contains healthy roots and leaves. When planting the rhizome, ensure it is not completely buried in the substrate to prevent rot. Over time, the plant will anchor itself and continue to grow.

Difficulty

Lagenandra ovata is considered medium in terms of difficulty. It requires stable water conditions, moderate lighting, and regular maintenance to thrive. While it’s relatively hardy, maintaining clean water through regular water changes and ensuring the plant has enough space to grow will support its health. With the right care, this plant will grow steadily and become a focal point in the aquarium or paludarium.

Short Description

Lagenandra ovata is a striking plant known for its tall, lush foliage, making it an excellent background plant in aquariums. It closely resembles Cryptocorynes but grows significantly larger. Its ability to grow both submerged and emerged makes it a versatile choice for aquascapes and paludariums. With a moderate growth rate and medium light requirements, it’s well-suited for both beginner and experienced aquarists. Regular trimming and propagation through runners or rhizome division will help maintain the plant’s health and fullness over time.
