Pogostemon stellatus - Plant

Pogostemon stellatus, also known as Eusteralis stellata, has slender leaves arranged in dense, star-shaped whorls around upright stems. Its leaves range from light green to orange, pink and reddish purple, depending on growing conditions. Mature stems can reach 20–60 cm, with crowns around 10 cm across, making it an impressive midground or background plant for larger aquariums.

Compared with the easy green ‘Octopus’ plant, Pogostemon quadrifolius, P. stellatus is more demanding and offers stronger orange, pink and purple colouration. Its fine foliage contrasts well with broad-leaved Hygrophila and Ludwigia. Plants grown above water may arrive compact and green before developing their characteristic underwater foliage.

Provide strong lighting, injected CO₂ and consistent fertilisation for reliable growth. Supply a complete range of nutrients, including trace elements, and favour soft to moderately hard water. Pale leaves can indicate a nutrient shortage, while abrupt changes in CO₂ or feeding can disrupt growth. Allow room around each crown, trim established stems to encourage branching, and thin crowded growth so light reaches the lower leaves. Growth may occasionally pause even under otherwise suitable conditions.

Plant individual stems into the substrate with adequate spacing to allow light penetration and water circulation. Provide strong lighting, stable CO₂ injection, and comprehensive fertilisation for the best colouration and compact growth.

Trim regularly to encourage side shoots and denser bush formation. Replant healthy tops after trimming to maintain fullness and expand plant groups. Ensure good flow throughout the aquarium to prevent debris accumulation within the fine foliage.
