Echinodorus argentinensis is a large Amazon sword plant with broad green leaves that rise from a central crown into a full, upright rosette. It is a big plant that wants room to spread, so it works best as a background feature or a standalone centrepiece in a larger tank.Give it space and a nutritious substrate and it grows steadily, sending up fresh leaves that can reach the water surface. Keep it looking its best by trimming away older outer leaves so the newer growth can come through. It is an easygoing plant that settles into most tank conditions and is happy under moderate lighting.Care at a glance Placement: Background or centrepiece Lighting: Medium CO2: Low, not required Growth rate: Moderate Difficulty: Beginner Colour: Green All our plants are harvested fresh and algae free.
