Echinodorus Aflame (Purple Knight Sword)

Echinodorus 'Aflame' is a sword plant that skips the green stage. New leaves emerge burgundy and darken toward purple as they harden, held in an upright rosette rather than the sprawling form most swords take. It gives a planted tank a red centerpiece without a single stem plant.

Grower's Notes

• Root tabs are what produce the color. Swords take nearly all their nutrition from the substrate. Water column dosing alone gives you a pale, slow Aflame; a fertilized root zone gives you the burgundy the plant is bought for.
• Never bury the crown. The growing point at the center of the rosette must sit at substrate level. Covered, it rots — the leaves go first and the plant does not come back.
• Emersed-grown stock resets after planting. The leaves it arrives with were formed out of water and will often melt away. Judge the plant on the leaves that follow, not the ones it came with.
• It propagates from flower stalks, not runners. A mature Aflame sends up an inflorescence that produces daughter plants along its length. Let each grow roots and two or three leaves before cutting it free.
• Old outer leaves are meant to be removed. Swords continuously shed their oldest leaves as new ones emerge from the center. Cutting yellowing outer leaves at the base keeps the rosette tidy and stops them fouling the water.

Notes

• Coloration may vary depending on lighting, nutrient availability, and tank conditions. For best results, provide enriched root tabs and CO₂. Avoid burying the crown of the plant to prevent rot.
• Never release aquarium plants into natural waterways.
