Ludwigia Peruensis (Ludwigia glandulosa)

Ludwigia Peruensis, also commonly known as Ludwigia Glandulosa, is a beautiful freshwater aquarium stem plant prized for its vibrant red, burgundy, and purple coloration. Its narrow, pointed leaves and rich colors make it an excellent choice for adding contrast and visual interest to planted aquariums.

This stunning aquatic plant develops its best coloration under strong aquarium lighting and with proper nutrient supplementation. Ludwigia Peruensis is especially popular in aquascaping, where its deep red foliage creates a striking contrast against bright green plants.

Lighting & Growth

Ludwigia Peruensis thrives under medium to high lighting, with stronger lighting helping produce its signature deep red and purple coloration.

Under lower lighting conditions, the plant may develop greener leaves, slower growth, and less compact stems.

CO2 supplementation is highly recommended for stronger growth, healthier foliage, and more vibrant coloration.

Planting & Maintenance

Ludwigia Peruensis grows best when planted directly into aquarium substrate. A nutrient-rich substrate or root tabs, combined with a balanced liquid fertilizer, can help support healthy development.

When planting, space individual stems slightly apart to allow light and water circulation to reach the lower leaves.

Regular trimming encourages bushier growth and helps maintain the plant’s desired height and shape.

To propagate, simply cut a healthy stem and replant the cutting into the substrate.

Aquarium Placement & Compatibility

Ludwigia Peruensis is an excellent choice for the midground or background of medium to large planted aquariums.

Its rich red coloration pairs beautifully with green aquatic plants such as Anubias, Java Fern, Cryptocoryne, and other stem plants.

This plant is compatible with most peaceful freshwater community fish and shrimp. Avoid keeping it with fish that aggressively dig through substrate or consume live plants.

Important Information

Ludwigia Peruensis requires consistent lighting, nutrients, and stable water conditions to maintain its best appearance.

Because this species can be more demanding than many beginner aquarium plants, it is best suited for aquarists with some planted tank experience.

For the best results, provide strong lighting, balanced fertilization, and CO2 supplementation to encourage healthy growth and vibrant red coloration.
