Also known as Mermaid Weed — An Unusual Beauty with Serrated Foliage
Proserpinaca palustris, commonly referred to as Mermaid Weed, is a visually striking stem plant celebrated for its finely serrated, almost feathery leaves that shimmer in hues ranging from bright green to deep copper-red depending on lighting and nutrient conditions. This North American native is a favorite among aquascapers looking to add texture, contrast, and a wild, natural touch to planted tanks.
Unique Leaf Shape: Delicate, saw-tooth foliage resembling aquatic ferns or lace adds eye-catching texture to aquascapes.
Color Variability: Green under moderate lighting; turns bronze to deep red under intense light and CO₂.
Midground to Background Use: Excellent for adding vertical interest and soft movement in flowing water.
Native Species: Grows naturally in marshes and slow-moving waters across the U.S., making it an eco-conscious choice.
Lighting: Medium to high; stronger lighting enhances red tones and leaf serration.
CO₂: Highly recommended for best growth and coloration, though not strictly required.
Water Parameters:
pH: 6.0–7.5
Temperature: 68–82°F (20–28°C)

♻️ Be a Responsible Aquatic Plants Owner
Please do not release Proserpinaca palustris or any aquarium plants into natural waterways. They can disrupt native ecosystems. Dispose of trimmings responsibly.
Return Policy: All sales are final
24 Hours Live Arrival Guarantee* - In a rare case of live stocks dead on arrival, we must be notified within 24 hours by the same day of delivery. Please take clear photos of the damaged product and send it to us within 24 hours. Live Arrival Guarantee will be void after 24 hours of delivery. All replacements are considered final and we will not replace the replacement.
Please be aware that our Live Arrival Guarantee is subject to certain conditions. Specifically, the guarantee will not be applicable in cases where the package is marked as 'invalid address', 'undeliverable' or is 'returned to sender.' This includes situations such as a vacant delivery address, a missing apartment number, or any other issues that prevent the postal service from delivering your package.
It is crucial to provide accurate and complete shipping information to ensure the successful delivery of your order and the applicability of the Live Arrival Guarantee.
Please keep in mind that Live Arrival Guarantee only guarantees that live stocks will be alive upon arrival. We cannot guarantee that you will continue to have success with them. Many factors, including the aquarium environment, water quality, nutrient, temperature, lighting, filter, and CO2 system, can contribute to the failure to grow live plants and live animals.
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.
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.
