Proserpinaca Palustris (Mermaid Weed)

Emersed Growth: Fresh-cut Plants

Price
$9.99

Want a leaf shape nothing else has? Mermaid Weed grows finely saw-toothed, almost lace-like foliage that shifts from bright green to deep copper-red under strong light. The serration is the draw — no other stem plant in the catalogue has that texture.

What You’ll Receive

  • Fresh-Cut Plants: Approximately 6 loose, freshly cut stems — unrooted and ready to plant directly into your substrate.
  • Bunched Plants: Approximately 6 unrooted, fresh-cut stems bundled together with foam and secured with a weight for easy placement.
  • Potted Plants: Approximately 6 unrooted, fresh-cut stems nestled in rockwool and housed in a net pot — ideal for stable planting and easy transfer.

Plant Profile

  • Common name — Mermaid Weed
  • Scientific nameProserpinaca palustris
  • Origin — North America, in marshes and slow-moving water
  • Placement — Midground to background
  • Mature height — 6–14 in
  • Growth rate — Medium

Care

  • Difficulty — Intermediate
  • Light — Medium to high. Intensity drives both the red and the leaf serration
  • CO₂ — Recommended, not required
  • Water — 65–78°F · pH 6.0–7.0. Prefers the cooler end, soft to moderately hard
  • Substrate — Required. Root and water column feeder
  • Growth habit — Amphibious. Suits paludariums and ripariums
  • Propagation — Stem cuttings

Grower’s Notes

  • Light changes the leaf shape, not just the colour. Under strong light the serration becomes pronounced and the plant reddens; under moderate light the leaves come in smoother and green. You are choosing the texture through your lighting.
  • It prefers cooler water than most. At 65–78°F it sits below the usual range, so it is a poor choice for a warm discus tank and does noticeably better in a room-temperature setup.
  • Trim and replant the tops. Each cut branches the stem, and replanted cuttings root readily.
  • It contrasts strongly with smooth-leaved plants — Anubias and Cryptocoryne are its natural companions.

  • Some aquatic plants are restricted in certain U.S. states — check before ordering, and never release aquarium plants into natural waterways.

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.

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.

Your cooperation in protecting the environment is appreciated. For continuously updated information, refer to the USDA State Noxious Weed list here.

Thank you for your responsible commitment to environmental preservation.

Customers praised this aquatic plant for arriving healthy with "excellent quality" and minimal melt. Shoppers noted plants adapt quickly to aquariums, "perked right up" after planting, and root fast with new growth. Some mentioned the "interesting shaped leaves" remain green initially, with red hues developing later. A few noted higher pricing but felt "quality beat the price."

  • Great addition to my planted aquarium. It had almost no melt and perked right up.
  • Came healthy and in the right amount.
  • They look great after planting. Very happy with this purchase!

Great addition to my planted aquarium. It had almost no melt and perked right up as soon as I got them intothe tank.

Interesting shaped leaves

I like the shape of these, and they seem to be taking root quickly. They've adjusted to my aquarium very well, and they've been sprouting new leaves. No signs of the red hue, all green so far, but maybe it'll show up as they mature.
