Hydrocotyle Verticillata: A Unique, Low-Growing Aquatic Plant

Latin Name: Hydrocotyle verticillata
Place of Origin: North and South America

Hydrocotyle verticillata is a distinctive aquatic plant prized for its unique appearance and ease of care. Known for its round, umbrella-like leaves, this plant brings a whimsical, natural feel to any aquarium. It’s often used as a foreground or carpeting plant due to its low-growing nature. Native to North and South America, Hydrocotyle verticillata thrives in shallow water and wetlands, making it adaptable to a variety of aquarium conditions.

Appearance

The standout feature of Hydrocotyle verticillata is its round, flat leaves, which are attached to long, slender stems. The leaves resemble tiny lily pads, creating a striking visual contrast with other aquarium plants. The plant grows horizontally, sending out runners to form a carpet across the substrate. Its low-growing habit (up to 10 cm tall) makes it ideal for aquascapes where ground cover is desired.

Aquarium Care and Requirements

Lighting:
Hydrocotyle verticillata prefers moderate to high lighting to maintain its compact, low-growing form. In lower light conditions, the plant may grow taller and become leggy, losing its desirable carpeting effect.

Substrate and Nutrients:
A nutrient-rich substrate is beneficial for Hydrocotyle verticillata, as it absorbs nutrients primarily through its roots. Regular fertilization with root tabs or liquid fertilizers will support healthy growth. The plant is not overly demanding but thrives best with a steady nutrient supply.

Water Parameters:

• Temperature: 68-82°F (20-28°C)
• pH: 6.0-7.5
• Hardness: Soft to moderately hard water (2-12 dGH)

CO2 Injection:
While Hydrocotyle verticillata can grow without CO2, providing CO2 injection will enhance its growth rate and help maintain its compact form. CO2 is particularly useful in high-light setups, ensuring the plant receives the necessary carbon to grow densely and healthily.

Pruning and Propagation:
This plant spreads by sending out runners that form new plants, making propagation simple. To encourage denser growth, regular pruning of older or taller leaves may be needed. Cut back any overly long stems to maintain a neat, even carpet. New plants will grow from the runners, which can be separated and replanted if desired.

Benefits to the Aquarium

Hydrocotyle verticillata not only adds visual interest with its round, lily pad-like leaves, but it also provides great coverage for small fish and invertebrates. Its sprawling growth creates a natural shelter for fry and shrimp, offering them protection from larger tank inhabitants. The plant also helps to improve water quality by absorbing excess nutrients, thus playing a role in algae prevention.

Conclusion

With its unique leaf shape and low-growing habit, Hydrocotyle verticillata is a fantastic choice for aquascapers looking to add a touch of whimsy to their tank. Whether used as a foreground plant or for carpeting, it offers an attractive, natural look. With proper lighting, nutrients, and occasional pruning, Hydrocotyle verticillata will thrive and spread, enhancing the beauty and health of any aquarium.
