Pogostemon stellatus

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Best utilized as a background focal point due to its striking colors and size. It should be planted in groups with adequate space between stems for light penetration. It draws the eye immediately and should be placed strategically.

Botanical form

Stem

A magnificent stem plant with fine, pointed leaves arranged in whorls. Under ideal conditions, the leaves exhibit vibrant shades of pink, purple, and orange. The stems can grow quite thick and tall.

Growth

Fast

The growth rate is fast under high light and heavy CO2 injection. It requires frequent trimming to prevent it from taking over the tank. If conditions are suboptimal, it will stunt and stop growing entirely.

Substrate

High

Pogostemon stellatus is notoriously demanding and requires a mineral-rich aqua soil to maintain its stunning crown coloration and prevent lower leaf loss. Its strong, invasive root system deeply penetrates the substrate to extract heavy quantities of macronutrients, making bottom fertilization indispensable. A substrate bed of 5 to 6 centimeters is recommended to physically support its thick stems and accommodate its widespread root structure.

Column fertilization

Recommended

Heavy water column fertilization is absolutely essential. It requires high doses of nitrogen, phosphorus, potassium, and trace elements. Daily dosing of iron is often necessary to achieve the best colors.

Root fertilization

Recommended

It requires a very rich substrate to thrive. Aqua soil supplemented with root tabs is highly recommended. A strong root system is necessary to support its rapid growth and high nutrient uptake.

Trimming

Regular

Trimming can be tricky, as the remaining bottom portion sometimes struggles to sprout new shoots. It is often best to uproot, discard the bottom, and replant the colorful tops. If topping, leave a significant portion of healthy stem behind.

Propagation

Cuttings

Propagated by stem cuttings, though care must be taken to use healthy shoots. Plant the cuttings deeply into a rich substrate. Ensure they receive immediate high light and CO2.

Sensitivity

Moderate

Notoriously sensitive to changes in water parameters, leading to 'stunting' where the growth tip stops developing. It demands intense lighting and high, stable CO2 levels. Extremely susceptible to shading.

Layout role

Midground, Background

A premier background or midground focal point plant. Its vivid colors provide a spectacular contrast to green plants. Very popular in Dutch style aquariums for creating strong color streets.
