General Description
Pogostemon stellatus, commonly known as Water star, is a striking aquatic plant originating from swamps in East and Southeast Asia, as well as in northern Australia. It belongs to the family Lamiaceae and is categorized under the order Lamiales. This fast-growing plant is characterized by densely-growing whorls with striking colors that can reach a width of 6-14 cm.
Aquarium Suitability
This plant is well-suited for aquariums and is a popular choice due to its stunning appearance. However, it is considered difficult to cultivate, requiring high light levels, a constant CO2 supply, and specific nutrient levels in the water column to thrive. It is essential to monitor nitrate, phosphate, and micronutrient levels to ensure successful cultivation.
Demands and Hardiness
Pogostemon stellatus has high demands when it comes to light and fertilization. Insufficient light can result in leaf loss lower down on the stem, while a lack of micronutrients may cause the leaves to turn yellow or even white in extreme cases. Maintaining stable nitrate (5-20 mg/l) and phosphate (0.2-2 mg/l) levels is crucial, as rapid changes in growing conditions can lead to issues such as crippled habit development in the plant.
Aquascaping & Usage
In aquariums, Pogostemon stellatus can be used as a background or midground plant, adding an optical highlight to the tank when its care requirements are met. Its attractive foliage and vibrant colors create a beautiful contrast against other broad-leaved green stem plants, enhancing the overall aesthetic of the aquarium.
Propagation
Propagation of Pogostemon stellatus can be achieved through cuttings. The plant develops lots of lateral shoots that can be trimmed and replanted to propagate new growth. Trimmed shoots can either replace the original plant or be used in other areas of the aquarium for propagation purposes.
Habitat and Distribution
In its natural habitat, Pogostemon stellatus is found in swamps across East and Southeast Asia, as well as northern Australia. The plant thrives in swampy environments and is commonly encountered in diverse variants due to its extensive distribution range.
