General Description
The Pogostemon sp. "E 401" is a plant species within the genus Pogostemon, belonging to the Lamiaceae family. It is commonly known as "star rotala, coarse" and originates from Asia. Often sold as an emersed plant, it reaches its full beauty when submerged in an aquarium. The submersed sprouts can grow up to 20 cm in diameter, with leaves measuring 2-5 mm wide in whorls of 6-11 per stem node.
Aquarium Suitability
Considered a wonderful addition to planted tanks, Pogostemon sp. "E 401" is a medium-difficulty plant suitable for aquariums with high light levels and well-fertilized substrates. It serves as an excellent indicator of nutrient levels in the water, with deficiencies leading to color fading and stunted growth. The plant thrives in a CO2-rich environment and can be propagated easily through cuttings, forming bushy groups that create a striking contrast against other aquatic plants.
Demands and Hardiness
In aquarium setups, this plant requires a temperature range of 24-28°C and tolerates fluctuations between 15-32°C. It thrives in high light conditions and prefers carbon dioxide levels ranging from 20-40mg/l. Nutrient-wise, Pogostemon sp. "E 401" requires nitrate levels between 10-50mg/l, phosphate concentrations of 0.1-3mg/l, and potassium levels of 5-30mg/l. It shows medium growth rates and is unsuitable for outdoor use in colder climates.
Aquascaping & Usage
Ideal for background and midground placement, Pogostemon sp. "E 401" adds depth and color to aquarium layouts. Its elegant appearance and bushy growth make it a popular choice for aquascaping projects, especially when aiming for a lush and vibrant aquatic environment.
Propagation
Propagation of Pogostemon sp. "E 401" is straightforward and can be achieved through cuttings. When cut, lateral shoots form from the base left in the tank, allowing for the creation of dense, visually appealing groups of plants.
Habitat and Distribution
While the exact habitat of Pogostemon sp. "E 401" in the wild is not specified, it is known to originate from Asia and is likely found in freshwater environments typical of the region. This species is cultivated and distributed by the Dennerle company under the name "Eusteralis species E 401," among other possible names.
