 Appearance

This plant is known for its graceful and colorful appearance.

• Leaves: It has narrow, delicate leaves that grow on upright stems. Under water, the leaves are long and narrow, a contrast to the round leaves of the marsh variety from which it gets its name ("round-leaved") .

• Coloration: The leaves can range from light green and pink to intense reddish-orange or red-violet. The most vibrant reds are achieved under optimal growing conditions .

• Growth Habit: It grows vertically but will produce many side shoots, especially with regular trimming, creating a compact and bushy appearance. It can also exhibit an elegant, overhanging growth pattern as it reaches the water surface .

 Care Requirements

While considered beginner-friendly, providing the right conditions will help this plant truly thrive and show its best colors .

 Planting and Propagation

• Planting: For best results, plant individual stems with some space between them. This allows light to reach the lower leaves and encourages bushier, horizontal growth .

• Propagation: This plant is very easy to propagate. Simply cut a healthy stem and replant the cutting into the substrate. It will quickly develop roots and grow into a new plant .

• Maintenance: Regular trimming is essential. Cut the tops of stems to encourage lateral shoots, which makes the plant bushier and more compact. This also prevents the lower leaves from being shaded .

 Aquascaping Uses

• Placement: Ideal for the midground to background .

• Contrast: Its fine texture and vibrant red color create a stunning contrast when placed next to plants with broader, green leaves .

• Grouping: It looks best when planted in a large group to form a dense, colorful bush .

 Potential Challenges

• Nutrient Deficiency: Pale or yellowing new leaves can indicate an iron deficiency . Stunted growth may mean a lack of other nutrients .

• Melting: Newly introduced plants may "melt" (lose their leaves) as they acclimate to a new tank. This is normal; simply remove the affected leaves and allow time for new growth .

• Algae: Because it requires high light, an imbalance of CO₂ or nutrients can lead to algae growth. Maintaining a balance is key .
