🌿 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.

Our Vitro Culture® plants are laboratory-grown in sterile conditions, offering several important benefits for aquarium hobbyists:

• Snail-free and pest-free plant material

WHAT WE CAN'T GUARANTEE

Even though our plants are very clean, but we can't guarantee they will be 100% pest-free because we cannot be responsible for your aquarium. Please use it at your own risk. We recommended all customers rinse the plants with clean water and quarantine them before use.

However, plants in tissue culture will be 100% free from pests, algae and never have been contacting with any aquarium.

1. Due to the nature of the product. We don't guarantee our plants will be pests free. ( snails, algae, hitchhikers )
2. We don't guarantee our plants will be free of pesticides. We use homemade, organic pesticides in our greenhouse to control pests. We do not use pesticides that contain copper. Copper is toxic to invertebrates such as aquatic snails, crabs, shrimps, etc
3. We don't guarantee your aquarium success or are responsible for your aquarium inhabitant including but not limited to fish, shrimp, snail, turtle, etc. So please quarantine all plants when use!
4. Unless specific, we don't guarantee aquatic plants will be grow emerged or submerge.

Please review your state's regulations on restricted plants, as we are committed to not shipping plants that are restricted in your area. Do not release any plants into the wild or waterways, as this can harm local ecosystems by introducing invasive species.
