Ludwigia sp. ‘Dark’ – The Moody Red of Aquascaping 🌑🌿

Ludwigia sp. ‘Dark’ is a striking stem plant known for its rich burgundy-to-brown leaves that bring a mysterious, dramatic tone to planted aquariums. Unlike brighter reds such as Ludwigia palustris ‘Super Red’, this variety leans into deeper shades—making it perfect for aquascapers who want subtle contrast and a more natural, earthy aesthetic.

Fast-growing under the right conditions, Ludwigia ‘Dark’ can be trimmed and replanted to form dense bushes or left to climb toward the water’s surface. Its color intensifies with strong light, CO₂, and iron-rich fertilization, but even in low-tech tanks it provides elegant dark-green foliage with hints of red.
