This is a very rare and beautiful stem plant. With proper nutrient lighting, and CO2, it will develop a stunning red color with dense needle like leaves and a large crown as big as 10cm in diameter. This plant is found in Brazil.
Even though rarely used in Takashi Amano's Nature Aquaria or in Dutch-style tanks, this Ludwigia variety is highly suitable to create red accents in Tonina tanks.
If you have soft water in your tank, don't hesitate to include this beautiful red plant into your design.
