01

Overview

Few stems are as adaptable to different aquascaping styles. Repeated trimming creates dense bushes, while strong stable conditions can encourage warmer coloration.

02

Aquascaping use

Plant a large group and shape the top line deliberately. Its fine leaves add depth behind coarse rosettes or stone.

03

Planting

Insert individual stems with small gaps. Replant healthy tops after trimming and periodically remove congested old bases.

Substrate note

Flexible; nutrient substrate improves rooting

04

Light & CO₂

It survives moderate conditions, but compact growth and color need stronger light plus stable carbon. Light alone does not guarantee red foliage.

Light requirementMediumIntensity categories are comparative, not precise PAR targets.
Supplemental CO₂BeneficialAll aquatic plants use CO₂; this describes whether injection is needed.

05

Substrate & fertilization

Dose complete water-column nutrients consistently. Avoid chasing color through severe nitrogen limitation, which can weaken growth.

Feeding behavior: Water-column feeder. Nutrient demand: moderate.

06

Growth, trimming & propagation

Top regularly and allow side shoots to form. Alternate trimming zones so the entire group does not look freshly cut at once.

Propagation method

Topping and replanting

Common problems

  • !Shaded bases lose lower leaves
  • !Unstable CO₂ distorts new tips
  • !Frequent topping is needed to hold a clean shape
