Dennerle - Heteranthera zosterifolia is available for pre-order – please confirm stock before ordering!
Introduction:
Heteranthera zosterifolia, commonly known as Stargrass, is a fast-growing and visually striking stem plant native to South America. Its name is derived from the way its bright green, narrow leaves radiate out from the stem, forming a star-like pattern. This plant brings a fresh, vibrant texture to aquascapes and is especially valued for its rapid growth and ability to fill in backgrounds with lush greenery. Its upright, bushy appearance also makes it ideal for creating contrast against more rigid or compact foreground species. A favorite among aquarists for both visual impact and oxygenation.
Care Requirements:
Water Parameters:
Temperature: 22–28°C
pH Range: 6.0–7.5
Hardness: Soft to moderately hard water (2–12°dGH)
Nutrient Requirements:
Heteranthera zosterifolia requires regular fertilization to support its vigorous growth. It benefits from a nutrient-rich substrate and water column dosing with micronutrients and nitrogen sources. CO₂ injection is highly recommended to maintain compact, vibrant growth, though it will still grow well without it under the right conditions.
Tank Setup:
Best suited for background or midground placement in medium to large aquariums, Stargrass grows tall and can be trimmed frequently to shape dense, bushy stands. Moderate to high lighting is essential for compact leaf development and to avoid legginess. It does best in fine gravel or aquasoil, and a steady water flow helps support healthy growth and leaf distribution.
Care Tips:
Regular trimming encourages branching and bushier growth. Replanting healthy tops promotes fullness while keeping the lower sections of the plant from thinning out. Ensure it is not overly shaded by other plants, as Stargrass needs light to thrive. Watch for signs of nutrient deficiencies (e.g., yellowing leaves) and adjust fertilization accordingly. Its rapid growth makes it effective at absorbing excess nutrients and combating algae.
Heteranthera zosterifolia is an excellent choice for aquarists looking to add vibrant greenery and soft texture to their aquascapes. With its star-shaped leaf arrangement and fast growth, it provides visual movement and fills out tanks beautifully, making it a favorite for both beginners and seasoned hobbyists.
