Giant Duckweed

Floating Plants: Small Portion

Price
$7.99

Duckweed you can actually remove. Spirodela polyrhiza has fronds several times the size of common duckweed and much longer trailing roots — which means it nets out in sheets instead of scattering, while still delivering the fast nutrient export and surface shade floaters are bought for.

What You’ll Receive

A small portion (approximately 2” × 2”) of healthy Giant Duckweed containing 10+ plants.

Plants are carefully harvested and packed to ensure they arrive fresh and ready to add directly to your aquarium or pond.

Plant Profile

  • Common name — Giant Duckweed
  • Scientific nameSpirodela polyrhiza
  • Placement — Free-floating on the surface
  • Size — Fronds roughly 0.2–0.4 in across
  • Growth rate — Fast

Care

  • Difficulty — Beginner
  • Light — Low to medium
  • CO₂ — Not required. It takes CO₂ from the air
  • Water — 65–85°F · pH 6.5–7.5
  • Substrate — Not required
  • Growth habit — True aquatic, free-floating
  • Propagation — Natural division

Grower’s Notes

  • Size is the practical advantage over common duckweed. Lemna minor is nearly impossible to remove once established because every 2mm frond repopulates the tank. Spirodela is big enough to net out properly — the same benefits with a working undo button.
  • Long roots make better fry and shrimp cover than common duckweed's stubby ones.
  • Surface flow packs it into corners where it rots. Aim filter returns downward or add a floating ring.
  • Thin it at every water change or it seals the surface and starves plants below of light.
  • Common duckweed often travels with floating plants — check a new portion before adding it if you're keeping the tank Lemna-free.

Notes

  • Pictures are sample representations. Portion size and frond count vary naturally.
  • Never release aquarium plants into natural waterways.

What We Guarantee

24-Hour Live Arrival Guarantee — We guarantee that live plants and live aquatic animals will arrive alive. In the rare case of a Dead on Arrival (DOA), you must notify us within 24 hours of the delivery time recorded on the carrier's official tracking page. The guarantee is void after that 24-hour window, as condition can no longer be attributed to transit.

How to Submit a Claim

  1. Take at least 2 clear, well-lit photos of the affected items in their original, unopened, sealed packaging, plus a photo of the shipping label on the box.
  2. Email your photos and order number to hello@aquariumplantsfactory.com within 24 hours of delivery.
  3. Do not photograph plants or animals after they have been unpacked, planted, or introduced to your aquarium — once an item enters your aquarium's ecosystem, it is no longer covered.

Approved claims are resolved with a replacement, store credit, or refund at our discretion, under the terms of our Refund Policy. Each item is eligible for one replacement only — replacements are final and we cannot replace a replacement.

Conditions That Void the Guarantee

  • Incorrect or incomplete shipping address (vacant address, missing apartment number, or any issue that prevents delivery)
  • Packages marked "invalid address," "undeliverable," refused, or returned to sender
  • Packages left unclaimed, held at a carrier facility at the customer's request, or not retrieved promptly after delivery — live goods must be brought indoors and unpacked the day they arrive
  • Carrier delays, weather events, or delivery exceptions once the package has left our facility
  • Shipments to freight forwarders or package-forwarding services

Providing accurate, complete shipping information and monitoring your tracking are essential to keeping your guarantee valid.

Please note: the Live Arrival Guarantee covers arrival only. We cannot guarantee ongoing success — aquarium environment, water quality, nutrients, temperature, lighting, filtration, and CO2 all affect long-term results.

What We Can't Guarantee

  1. Pest-free plants (potted & bare-root): Although our plants are grown in our own clean greenhouse, we cannot guarantee they are 100% free of snails, algae, or other hitchhikers. We recommend rinsing and quarantining all plants before adding them to your aquarium. Tissue culture (in vitro) plants are the exception — they are grown in sterile lab conditions, are 100% free of pests, algae, and disease, and have never been in contact with any aquarium.
  2. Pesticide-free plants: We use homemade, organic pest control in our greenhouse and never use copper-based pesticides, which are toxic to invertebrates such as snails, crabs, and shrimp. However, we cannot guarantee plants are entirely pesticide-free — always rinse and quarantine before use in invertebrate tanks.
  3. Your aquarium's success: We are not responsible for your aquarium inhabitants, including fish, shrimp, snails, and turtles. Please quarantine all plants before use.
  4. Growth form: Unless specified, we do not guarantee plants will grow emersed or submersed in your particular setup.

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.

Beyond Expectations

The plants I ordered arrived late (due to USPS delays) but the plants themselves were just fine! I was worried that the water lettuce would have issues with condensation or else have roots that were dried out / totally not the case! I got more plants in each package than I expected and they all arrived healthy and undamaged. Thank you!

Plants are all doing really well.

I put the plants in a couple days ago and no signs yet of any melting or problems. I’m very satisfied and would use them again.

Small Portion = 3 plants

This is the first time that I've been less than satisfied with a shipment from Aquarium Plants Factory. The quality of the product was as good as past shipments but the quantity (only 3 plants in a plastic pkg the size of a large postage stamp) was insufficient to allow me to re-establish in my tank. Within 2 days my plecostomus had eaten all of them.
