🌿 Proserpinaca Palustris 'Cuba' (Mermaid Weed) – Vibrant Serrated Aquarium Stem Plant

Proserpinaca palustris 'Cuba', commonly known as Mermaid Weed, is a unique and highly decorative aquarium stem plant admired for its dramatic leaf transformation and vibrant coloration. Under moderate conditions, the plant develops bright green leaves, while stronger lighting and CO₂ encourage the formation of finely serrated foliage with stunning copper, orange, and reddish tones.

This distinctive species creates beautiful vertical accents in aquascapes and offers striking texture compared to traditional smooth-leaf stem plants. Its delicate, needle-like leaves and dramatic color shifts make it a favorite choice for aquascapers seeking both contrast and visual depth in planted aquariums.

Grown in sterile laboratory conditions, this Vitro Culture® 4-inch bag provides clean, pest-free plant material ready to be divided into multiple healthy plantlets for planting in your aquarium.
