Ludwigia ovalis 'Pink'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Its brilliant pink coloring makes it an exceptional midground focal point in a planted aquarium. Like the standard form, it naturally grows at an angle, making it perfect for sweeping across the mid-level of the aquascape. Surrounding it with dark green or very light green plants will make its pink foliage pop.

Botanical form

Stem

It retains the defining alternate leaf arrangement and oval leaf shape of L. ovalis. However, under optimal conditions, the foliage of the 'Pink' variant turns a stunning, uniform shade of pink to light red. The stems remain relatively delicate but are robust enough to form a self-supporting bush.

Growth

Medium

This variant grows at a moderate pace, allowing aquascapers to easily maintain its shape without constant trimming. When provided with high light and CO2, its growth accelerates, but it rarely becomes invasive. This steady growth habit makes it a joy to work with in meticulously planned layouts.

Substrate

Medium

Thrives in a moderately enriched substrate that provides the necessary nutrients to bring out its distinctive pink hues. An aqua soil or fertilized gravel bed of about 2 inches deep is ideal for allowing the roots to anchor and feed effectively. Regular substrate nourishment ensures the plant maintains its robust stem structure and vibrant coloration.

Column fertilization

Recommended

Liquid dosing is crucial for this plant; iron and micronutrients must be consistently available in the water column. Deficiencies will quickly cause the new leaves to pale, losing their signature pink color and reverting to yellow or green. Adequate potassium ensures the leaves remain free of pinholes.

Root fertilization

None

A nutrient-rich aquasoil provides an excellent foundation for this plant. While it draws nutrients through its leaves, strong root fertilization promotes thicker, healthier stems and larger leaves. Adding root tabs near established clusters can provide an extra boost of color and vitality.

Trimming

Occasional

Trim the stems strategically to promote horizontal branching and create a dense, colorful thicket. Cutting just above a healthy leaf node encourages the stem to produce two or more new shoots. The vibrant pink tops should always be replanted to maintain the group's best appearance.

Propagation

Cuttings

Propagation is simple and effective through stem cuttings. Carefully snip the tops of the stems and gently plant them into the substrate. The cuttings will root quickly, provided there is adequate light reaching the substrate level.

Sensitivity

Moderate

It is somewhat more sensitive to shading and low light than the standard Ludwigia ovalis. If placed in a shaded area, it will rapidly lose its pink coloration and may begin to shed its lower leaves. Sudden swings in water parameters can cause the delicate new growth to become stunted.

Layout role

Midground, accent, Background

The 'Pink' variant is primarily used to introduce a soft, yet striking, splash of color into the midground. Its unique creeping habit allows it to blend seamlessly into hardscape or transition zones. It is a favorite among aquascapers for adding a touch of elegance and warmth without overpowering the design.
