Marsh Ludwigia
Ludwigia palustris
Onagraceae
About
Marsh ludwigia is a widespread, adaptable stem plant that ranks among the hardiest of the red-tinted aquarium species. Under low to moderate light it grows leafy and green to olive, while stronger light paired with CO2 and iron pushes the oval leaves into deep red and bronze tones. Forgiving of a broad range of parameters, it is an excellent introduction to coloured stem plants for the midground or background.
Care
Plant stems in nutrient-rich substrate with moderate light; add CO2 and iron-rich ferts to bring out red colour. Trim regularly and replant the healthy tops to keep growth bushy.
Diet
Feeds from both the substrate and the water column; iron and trace-element dosing intensifies the red pigmentation while macros support steady growth.
