Rotala ‘Pearl’ is a beautiful compact stem plant distinguished by its exceptionally small, delicate leaves and dense growth habit. Unlike many taller Rotala varieties commonly used as background plants, ‘Pearl’ can be maintained considerably lower, making it particularly valuable for detailed foreground and midground planting.

Under good lighting, stable CO₂ and balanced nutrition, the plant develops dense clusters of tiny leaves with attractive green to warm pink and reddish tones. Its extremely fine texture gives an aquascape a sense of scale and detail, making it especially useful in smaller aquariums and highly detailed Nature Aquarium layouts.

With regular trimming, Rotala ‘Pearl’ can be shaped into a compact, rounded bush, creating a beautifully refined transition between carpeting plants and taller stem plants.

Key Features:

• Exceptionally Fine Foliage: The tiny leaves give Rotala ‘Pearl’ a delicate appearance and create exceptional detail within an aquascape.

• Compact Growth Habit: Compared with many other Rotala varieties, ‘Pearl’ can be maintained relatively low and dense, making it particularly useful in the foreground and midground.

• Beautiful Colour Potential: Depending on growing conditions, foliage can range from fresh green to warmer pink and reddish tones.

• Excellent for Detailed Aquascapes: Its miniature appearance helps create a greater sense of scale, making it particularly attractive in nano tanks and intricate aquascaping layouts.

• Responds Well to Trimming: Regular pruning encourages branching and allows the plant to form a dense, compact bush.

Care Requirements:

• Lighting: Medium to high lighting is recommended. Strong lighting encourages tighter internodes, denser growth and improved colouration.

• CO₂: CO₂ supplementation is highly recommended to maintain healthy, compact growth. Stable CO₂ is particularly beneficial when growing this plant under stronger lighting.

• Water Parameters: Rotala ‘Pearl’ performs well at temperatures of approximately 22–28°C and generally prefers slightly acidic to neutral water.

• Nutrition: Consistent macro- and micronutrient availability is important. Balanced fertilisation supports healthy new growth and attractive colour development.

• Trimming: Regular trimming encourages side shoots and helps maintain the characteristic dense, compact appearance. Healthy trimmed tops can be replanted to expand or rejuvenate the group.

Planting Tips:

• Separate individual stems and plant them carefully into the substrate with a small amount of space between each stem.

• Plant several stems together to establish a dense group while still allowing sufficient light and water circulation around the lower foliage.

• Use Rotala ‘Pearl’ in the foreground or midground where its miniature leaf structure can be appreciated.

• Regular trimming is particularly important if you want to maintain a low, rounded bush rather than allowing the stems to grow vertically.

• Replant healthy trimmed tops to thicken the group and replace older stems when necessary.

• Its very fine foliage works particularly well alongside carpeting plants, small-leaved Bucephalandra, rocks and detailed wood arrangements.

• For the most compact growth and strongest colouration, provide good-quality lighting, stable CO₂ and consistent balanced fertilisation.

With its tiny leaves, compact growth and refined texture, Rotala ‘Pearl’ is an excellent choice for aquascapers looking for something more delicate than a conventional stem plant. Its ability to form finely textured, compact groups makes it particularly valuable for detailed aquascapes where scale, texture and precise plant placement are important.
