Ludwigia glandulosa - Immersed Potted Plant

Ludwigia glandulosa, commonly known as the "Red Star Ludwigia," is a stunning and vibrant aquatic plant that hails from the Onagraceae family. It is cherished for its striking crimson or reddish leaves, which bring intense color and elegance to freshwater aquariums. This plant is favored by aquarists for its aesthetic appeal and its ability to create visually captivating aquatic landscapes.

Physical Characteristics:

1. Leaf Structure: The leaves of Ludwigia glandulosa are lance-shaped, often displaying colours ranging from deep green to rich red or even shades of purple. The intensity of the red coloration can vary based on lighting and water conditions.

2. Growth Form: This plant can exhibit both submerged and emersed growth forms. Submerged growth in aquariums leads to the development of long, graceful stems with closely set leaves, creating a bushy and eye-catching appearance.

3. Root System: Ludwigia glandulosa develops a network of fine roots that anchor it in the substrate, while also absorbing nutrients and stabilizing the plant.

Aquarium Requirements:

1. Lighting: High to very high lighting is recommended for Ludwigia glandulosa to encourage and maintain its vibrant red coloration. Insufficient light can result in greener leaves.

2. Substrate: A nutrient-rich substrate is beneficial for this plant, as it absorbs nutrients through its roots. A substrate supplemented with root tabs can further support its growth.

3. CO2 Injection: The addition of carbon dioxide (CO2) is beneficial for promoting healthy growth and vibrant coloration, especially in high-tech aquarium setups. However, it can be cultivated without CO2 injection in lower-tech tanks.

4. Water Parameters: Maintain water conditions within a pH range of 6.0 to 7.5 and a water hardness level of soft to moderately hard. The temperature should ideally be between 20 to 28°C.

Propagation: Propagation of Ludwigia glandulosa is achieved through cuttings. When the plant grows taller or becomes too dense, you can trim the tops and replant them in the substrate to encourage new growth.

Maintenance: Regular pruning is necessary to keep Ludwigia glandulosa in the desired shape and to maintain its aesthetic appeal. Removing older or discoloured leaves is important to encourage the growth of new, vibrant ones.

Aquascaping Use: Ludwigia glandulosa is a popular choice for midground and background placements in aquascaping layouts. Its striking red or purple coloration adds a captivating contrast to green plants and creates a focal point in the aquarium.

Challenges: Maintaining the intense red coloration in Ludwigia glandulosa can be challenging, especially in lower lighting conditions. Adequate lighting and nutrient supplementation are key to preserving the plant's vibrant appearance.

Ludwigia glandulosa is a breath-taking addition to freshwater aquariums, known for its stunning coloration and visual impact. Its elegant appearance and unique growth habit make it a valuable asset for aquascaping projects. By providing the appropriate care and conditions, aquarists can enjoy the enduring beauty and captivating aesthetics that Ludwigia glandulosa brings to their aquatic displays.
