Ludwigia Palustris (Ludwigia palustris)

Ludwigia palustris is a compact, small-leaved red stem that colors up at lower light than almost any other red plant — solid medium light produces rusty red tops even without CO2. Its modest height makes it one of the few reds that fits comfortably in the midground of a small tank.

Frequently asked questions

How is Ludwigia palustris different from Ludwigia repens?

Palustris is smaller in every dimension — shorter stems, smaller leaves — and generally reddens more readily at moderate light. Repens grows taller and faster, making it the better pure background plant, while palustris suits midground bushes and nano tanks.

Can Ludwigia palustris turn red without CO2 injection?

Yes — it is one of the most reliable low-tech reds. Give it unshaded medium-to-strong light and keep nitrates on the leaner side, and the upper halves of the stems develop a genuine red rather than the olive blush most species manage without gas.
