Peplis diandra

Peplis diandra (syn. Didiplis diandra) is closely related to the genus Didiplis and is native to shallow wetlands and temporary pools of Europe. In the aquarium it forms low-growing creeping stems bearing pairs of small, rounded green leaves, creating a fine-textured foreground or midground accent. It requires the high light and CO2 conditions common in high-tech competition setups but is otherwise uncomplicated in its nutritional demands. Its rarity in the trade adds collector appeal for aquascapers who seek genuine variety in their plant palette.

Light: High; 65–90 PAR for compact, dense growth. CO2: Required; 25–35 ppm for healthy leaf production and spread. Water: pH 6.0–7.5, soft to moderately hard. Planting: Plant stem clusters 2–3 cm apart in the foreground; allow to spread naturally. Growth: Moderate; trim periodically to maintain neat height and prevent leggy stems.
