Posted by Max Gandara on on 28th Dec 2023

Eriocaulon Polaris, known as the Arctic Star, is a captivating aquatic plant that graces aquariums with its unique appearance and delicate charm. As a member of the Eriocaulaceae family, this species is native to regions in Asia, including India and Southeast Asia. Its distinctive rosette shape and exquisite details make it a sought-after choice among aquascapers looking to add a touch of elegance to their underwater landscapes.


Eriocaulon Polaris is recognized for its compact rosette form, consisting of intricate leaves arranged in a spiral pattern. The plant boasts slender, linear leaves with a distinctive silver-green coloration, creating a visually striking contrast against the backdrop of the aquarium. As it matures, a central stem emerges, producing small white or yellow flowers that add an extra layer of sophistication.

In its natural habitat, Eriocaulon Polaris is found in marshy areas, submerged in shallow water or on wet substrates. These habitats are typically characterized by acidic to neutral water conditions and moderate lighting. The plant's adaptation to such environments makes it well-suited for aquariums where it can thrive under similar conditions.

Cultivating Eriocaulon Polaris requires attention to specific parameters. This plant thrives in soft, acidic to neutral water with a pH ranging from 5.5 to 7.5. Moderate to high lighting conditions are ideal, and CO2 supplementation can enhance growth and coloration. A nutrient-rich substrate and a balanced fertilization routine contribute to the overall health and vibrancy of the Arctic Star.

Eriocaulon Polaris is revered for its aesthetic contributions to aquascaping. Its compact form and distinctive color make it an excellent choice for creating focal points or adding intricate detail to midground or background areas. When strategically placed among rocks or driftwood, Eriocaulon Polaris elevates the visual appeal of the aquarium, resembling a celestial star in the aquatic cosmos.

Propagation of Eriocaulon Polaris involves the division of its rosettes. As the plant matures, it produces side shoots or offsets that can be carefully separated and replanted. Regular pruning and removal of old or decaying leaves help maintain the plant's vitality and encourage new growth. Consistent monitoring of water parameters and routine maintenance contribute to its overall well-being.

Eriocaulon Polaris is considered a bit demanding in terms of care. It may experience melt or growth inhibition when introduced to a new environment. Providing stable water conditions, appropriate lighting, and gradual acclimatization can help minimize stress. Additionally, maintaining good water circulation ensures nutrient distribution and prevents stagnation.

Eriocaulon Polaris, the Arctic Star, stands as a testament to the artistry and diversity present in the world of aquatic plants. Its intricate form and captivating coloration make it a cherished addition to aquascapes, where it adds a touch of celestial beauty. As aquascaping continues to evolve as an art form, Eriocaulon Polaris remains a shining star, contributing to the creation of enchanting underwater realms that captivate the imagination of aquarists worldwide.
