Argentine Sword
Argentine Sword
Argentine Sword is a South American sword plant producing noticeably broader leaves than the classic Amazon Sword — creating a fuller, more visually substantial background rosette with more visual mass per individual leaf. The broader leaf form provides more natural shelter for fish and creates a bolder, more dominant background presence that suits larger aquariums where a genuinely impressive plant is wanted.
Care tip: Argentine Sword is a root feeder that benefits greatly from a nutrient-rich substrate or regular root tabs. Maintain temperatures of 72–82°F and pH 6.5–7.5. CO₂ is not required for this variety.
Growing to 16 to 20 inches, Argentine Sword is a natural background plant for medium and larger aquariums. The broader-than-average leaves create significant visual mass and natural shelter in the background zone. Root tabs or a nutrient-rich substrate support the best growth — the broad leaf form is most impressively developed in plants with consistent root zone nutrition.
This easy plant requires no CO₂ supplementation and grows under medium lighting. Temperatures between 72 and 82°F and a pH of 6.5 to 7.5 provide comfortable conditions. Its adaptable, easy-growing nature is shared with other Amazon Sword relatives, making it a reliable and forgiving background plant suitable for aquariums at every level of technical sophistication.
In the aquascape, Argentine Sword provides bold, broad-leaved background structure with more visual mass per individual leaf than narrower Amazon Sword variants. The wider leaves create stronger visual presence and more substantial shelter. In larger aquariums it is a natural and impressive centerpiece — its broad leaf form creates a fuller, more visually dominant background presence than the slender-leaved sword varieties.
Argentine Sword is a reliable, bold, and naturally beautiful broad-leaved sword for aquarists who want the classic Amazon Sword character with added visual mass and leaf breadth. Its broader leaves and easy care make it a naturally impressive and practically dependable background plant for medium and larger planted aquariums.
