Hygrophila lacustris
Hygrophila lacustris
Hygrophila lacustris is a North American native stem plant producing bright, narrow lance-shaped leaves on upright stems that create lush, bright green background coverage in planted aquariums. Its North American origin makes it an authentic choice for biotope setups representing the rivers and wetlands of eastern North America, and its reliable growth and adaptable nature make it a practical background plant for a wide range of planted tank styles.
Care tip: Hygrophila lacustris grows best in moderate to high lighting with CO₂ optional. Maintain temperatures of 68–82°F and pH 6.0–7.5. Regular liquid fertilization supports healthy growth and best coloration.
Growing to 6 to 12 inches, lacustris is a compact and tidy background to midground plant that responds well to trimming. Its bright, narrow leaves create a lighter, more delicate background texture than the broader-leaved Hygrophila corymbosa forms. The bright green coloration is clean and vivid, providing a natural fresh-green backdrop that suits any aquascape style.
This easy plant grows in moderate to high lighting with CO₂ optional. The temperature range of 68 to 82°F reflects its North American origin and genuine tolerance for cooler conditions. A pH of 6.0 to 7.5 provides comfortable growing conditions. Regular liquid fertilization maintains the bright green color and supports steady, healthy growth.
In the aquascape, Hygrophila lacustris provides bright, narrow-leaved background coverage that suits nature-style and biotope compositions. The lighter, more delicate leaf form contrasts naturally with broader-leaved plants and creates useful variation within the background zone. In North American biotope setups it is an authentically appropriate species alongside native fish.
Hygrophila lacustris is a reliable, attractive, and botanically interesting North American background plant for aquarists who appreciate regional authenticity and practical ease of care. Its bright narrow leaves and adaptable nature make it a versatile and underappreciated background species.
