The best frogbit plants, compared.
Top pick: Aquarium Fan 3 large Amazon frogbit Best value: AquaPlants American frogbit, 3 plants – Lowest shelf price for a named species sold as a stated count of three plants, about £7.09. Updated October 2026.
Frogbit on amazon.co.uk is a free-floating plant, and the twelve listings are live plants. Eleven titles are frogbit, laevigatum where the Latin name is printed, and one is American frogbit, spongia. You judge a listing by the species on the title, whether it is a tissue-culture cup or a counted bunch, whether the water surface stays calm, and whether anyone in the UK has reviewed it. A title that says pond does not make a tropical floater safe to leave outside through a British winter. Species, cup and pack size are set out in the [frogbit buying guide](/hub/garden-ponds/frogbit/sub/frogbit-buying-guide). You are choosing a live plant, not a pump, a liner or a fertiliser. One listing is American frogbit, spongia, with a bullet that leaves can reach 20 cm wide. The native plant is not in these twelve rows. A genus-only title, or a title with no scientific name, does not tell you which is in the bag. Bunch titles claim 3, 5, 6 or 10 plants, but the unit-count field is 1.0. One reviewer received four plants against a title that says three. A title count is not plants that arrived.

Personal buying guide
Question 1 of 2
Where will the plant sit?
This Aquarium Fan listing is three loose Limnobium laevigatum plants at £12.99, marked indoor and partial sun. The star line is 4.4 out of 5 from five reviews, and three of those texts are saved. One buyer saw new leaves after an unpromising arrival, one was impressed with the quality, and one said the plants spread in a wildlife pond and arrived packaged. Fish in a barrel nibbled the leaves, and one order contained four plants against a title count of three. The height field says 15 cm while a bullet says the plants are 1–5 cm tall with leaves 5–15 cm wide. Temperature and CO2 are not stated. Five reviews are a thin sample, and the pond use is one wildlife pond, not an answered listing question.
Pros
Cons
Best for: You want three loose Amazon frogbit plants for a quiet indoor surface and you can accept a thin set of reviews.
Less suitable: You want a large review sample, or one height figure you can plan a tank around.
Specifications
Common questions
Does the listing say the plant adds oxygen?
The page asks whether it can oxygenate the water and does not answer.
Which size should you read?
The bullet says 1–5 cm tall and leaves 5–15 cm wide. A separate height field says 15 cm.
What do the saved reviews say?
The star line is 4.4 from 5. Three UK texts mention new leaves after a poor arrival, use in a wildlife pond, and fish that nibbled a piece.
The Tropica 1-2-GROW cup, part 063 TC, is one tissue-culture pot of Limnobium laevigatum at £10.00, listed as indoor with partial shade. Across 97 amazon.co.uk reviews the line is 3.9 out of 5, and that is the only large sample in this set, which is why it is the top pick. Buyers who received living plantlets describe a weak start that then rooted and spread, cover that bettas used, and in one case less algae. The same reviews keep returning to yellow leaves with no roots, melt after about a week, brown or mouldy gel, and plants that were mostly dead once they went into a pond. Snails turn up in reviews even though the bullets call the culture snail free, and a moving water surface is linked to die-off. The cup can hold fewer plantlets than the photograph, and roots break when you separate them. Temperature, CO2, and the outdoor-pond question are unanswered, so the listing you can check is an indoor aquarium plant.
Pros
Cons
Best for: You want a named Amazon frogbit culture for a still indoor tank and you can wait out a weak first week.
Less suitable: You need a plant already described by buyers in a pond, or a cup that arrives full and snail-free every time.
Specifications
Common questions
Is this listing marked for an outdoor pond?
The page asks whether it can be used in outdoor ponds and does not answer. The indoor/outdoor field says Indoor.
What light does the listing state?
Partial shade. A separate question about special lighting is unanswered.
What do the amazon.co.uk reviews cover?
The listing line is 3.9 out of 5 from 97 reviews. Saved texts mention fast growth after a poor start, and also yellow leaves, melt, snails and dead plants.
AquaPlants lists three Limnobium spongia plants at £7.09, the lowest price in this set, with indoor and partial shade on the page. The title uses the common name American frogbit, and a bullet says the leaves can reach 20 cm wide and that the plant is not very suitable for small aquariums. The listing has no customer-review line, so there is no star rating and no arrival report to quote. Questions about an outdoor pond, special lighting, and ease of care are on the page and left unanswered. The manufacturer line is Aquarium Fan and the country of origin is Latvia, which does not tell you how the plants travel. At £7.09 for a stated three plants it is the best value on shelf price, and that is a price fact, not a growing result.
Pros
Cons
Best for: You want the lowest price for a named three-plant listing and your tank can take wide leaves.
Less suitable: You want amazon.co.uk reviews before you buy, or you keep a small aquarium.
Specifications
Common questions
Will the listing suit a small aquarium?
The bullet says leaves can grow up to 20 cm wide and that the plant is not very suitable for small aquariums.
Is outdoor use answered?
The page asks about outdoor ponds. The indoor/outdoor field says Indoor. No answer is printed.
Is there a star rating?
No customer-review line is on the listing, so there is no star rating to quote.
Live Seeds asks £7.35 for a title count of three Amazon frogbit plants and names the genus Limnobium without a species epithet. The care line is 18–30 °C, moderate to high light, and no CO2, with flow kept gentle and off the leaf tops. The unit-count field says 1.0, so the three plants sit in the title rather than in the piece count. There is no customer-review line, no colour, no height, and no country of origin. The bullets promise a floating cover for fish and shrimp and rapid growth, which is the seller's wording, not a buyer report. You cannot tell from this page whether the plants are Limnobium laevigatum or another Limnobium.
Pros
Cons
Best for: You want a low three-plant title and you already know which Limnobium you are growing.
Less suitable: You need a species epithet or any amazon.co.uk review of this ASIN.

Common questions
What temperature does the care line state?
The shared Live Seeds care line states 18–30 °C. There is no separate test on this listing.
Does the listing say CO2 is required?
The care line says CO2 is not required because the plant absorbs CO2 from the air.
How many plants are stated?
The title states 3. The unit-count field says 1.0 count. There is no customer-review line on the listing.
This Live Seeds pack is £7.40 and the title says three Amazon frogbit plants with no CO2 required. The care block states 18–30 °C, moderate to high light, still or gentle flow, and CO2 taken from the air. No scientific name appears, and the unit-count field is 1.0 against a title count of three. The listing has no star line and no review text. Rapid growth and a green surface layer are bullet claims, not measured results. At five pence more than the other three-plant Live Seeds listing, the difference on the page is the no-CO2 wording in the title, not a separate specification.
Pros
Cons
Best for: You want a three-plant Amazon frogbit title that already says no CO2.
Less suitable: You need the species epithet or a buyer report of what arrived.

Live Seeds lists five Amazon frogbit plants at £9.20 and puts Limnobium on the title without a species epithet. Care is the shared block: 18–30 °C, moderate to high light, no CO2, and gentle flow. The piece-count field is 1.0, so five plants are a title claim. No customer reviews are stored for this ASIN. The bullets are the same floating-cover and rapid-growth lines used on this seller's other counts. Five plants at £9.20 works out at £1.84 each only if that title count arrives, which this page does not show.
Pros
Cons
Best for: You want a five-plant title with the genus on the page.
Less suitable: You want Limnobium laevigatum named, or reviews of this ASIN.

Live Seeds asks £14.80 for a title count of ten Amazon frogbit plants and names Limnobium without a species epithet. The care line is 18–30 °C, moderate to high light, no CO2, and flow kept off the leaves. The unit-count field is 1.0, and there is no customer-review line. The page asks, and does not answer, whether the plants suit cold water, how fast they grow, and whether fish can eat them. A best-seller rank is stored, 56,741 in Pet Supplies and 270 in Live Aquarium Plants, which is a catalogue position, not a growing trial. Ten plants at the highest Live Seeds price in this set still do not identify the species.
Pros
Cons
Best for: You want ten plants and the genus on the title, and you do not need those three questions answered.
Less suitable: You are buying for cold water, or you want reviews of this ASIN.

Live Seeds prices five Amazon frogbit plants at £9.50 and repeats no CO2 in the title. The care line agrees: CO2 is not required, the range is 18–30 °C, and light is moderate to high, with splash kept off the leaf tops. No species name and no review line are on the listing. The unit-count field reads 1.0. The two bullets, a floating cover for fish and shrimp and rapid growth, match the three-plant and ten-plant packs from the same seller. You pay £9.50 for a larger title count than the £7.40 three-pack, not for a different care specification.
Pros
Cons
Best for: You want five plants on the title and a no-CO2 care line.
Less suitable: You need a named species or a review of how many plants arrived.

The title sells five Amazon frogbit plants at £9.40 as cover for guppy fry and breeding tanks. Care is 18–30 °C, moderate to high light, no CO2, and flow kept off the leaves. The species epithet is absent, and the unit count is 1.0. There is no review line. The image URL matches the 10-plant pack B0GRSHH5SZ, so the photograph does not show this count on its own. Fry cover is a title phrase. Nothing stored from amazon.co.uk buyers describes fry using this plant.
Pros
Cons
Best for: You want a five-plant title aimed at a guppy breeding tank.
Less suitable: You need a photo that matches this count, or reviews that mention fry.

This Live Seeds title is six Amazon frogbit plants at £10.80 and calls them a pond and aquarium bio-filter. The care block is 18–30 °C, moderate to high light, no CO2, and gentle flow, with no species epithet. The unit count is 1.0, and there is no customer-review line and no best-seller rank. Pond and bio-filter appear in the title only. No stored review shows nutrient removal or how the plants behave in a UK pond, because the listing has no reviews. At £10.80 the six-plant title costs more than the Tropica cup, which does have 97 reviews, and it does not name the species.
Pros
Cons
Best for: You want a six-plant title and you will treat the pond wording as untested.
Less suitable: You need buyer reports from a pond, or a named species.

Live Seeds lists ten Amazon frogbit plants at £14.45 and puts no CO2 in the title. Care matches the other packs: 18–30 °C, moderate to high light, CO2 from the air, and gentle flow. The species is not named, the unit count is 1.0, and there is no review line. The image URL is the same as the five-plant listing B0GRSL4SM7, so the picture is not evidence of ten plants. Ten at £14.45 is about £1.45 each on the title arithmetic, which the piece-count field does not confirm. The bullets stay the shared floating-cover and rapid-growth lines.
Pros
Cons
Best for: You want a ten-plant title with the no-CO2 line and you will not treat the shared photo as the count.
Less suitable: You need a photo of this pack, a species name, or reviews.

The title is ten Amazon frogbit plants at £14.50, home grown, and described by the seller as suitable for nano tanks. Care is the shared 18–30 °C, moderate to high light, no CO2, and gentle flow, and the species epithet is missing. The unit count is 1.0 and the listing has no reviews. The nano-tank wording sits on the title only. This page gives no leaf width, so you cannot check that claim against a small tank. The seller's nano line is not a result from amazon.co.uk buyers.
Pros
Cons
Best for: You want a ten-plant title and you will judge the nano wording against your own tank.
Less suitable: You need a stated leaf size or reviews before you float it in a small tank.

Twelve amazon.co.uk listings were scored from the stored pages and the UK review notes already saved. Shelf date 19 October 2026. There is no laboratory test. A line such as rapid growth, bio-filter, nano tanks or snail free is the listing claim, not a measured result. A missing review line is not scored as a star rating. A title count is not scored as plants that arrived. These listings are not scored as winter-hardy pond plants. The highest score is the top pick. The best value is the lowest shelf price for a named species sold as a stated count of plants, once the large-sample listing already holds the top score. The weights below sum to 100.
Amazon evidence
25%The star line on amazon.co.uk. No customer-review line scores 0. Five reviews, with three texts saved, stay well below a sample of 97. A 4.4 from five does not outrank a 3.9 from 97.
Listing fit
35%A named species scores above a genus-only title, and a stated count in the piece field scores above a count that exists only in the title. Points come off for a height field that disagrees with the size bullet, a shared image across two ASINs, a unit count of 1.0 against a multi-plant title, and a pond, bio-filter or nano claim that the bullets do not specify. Temperature and CO2 stated on the page score up.
Review outcome
25%Texts that match this product score up when they describe new leaves, a living arrival or spread. Melt, dead plants, snails despite a snail-free line, a moving surface linked to die-off, an under-filled cup, broken roots and fish damage score down. No review text scores 0. The same complaint is not counted twice.
Value
15%Shelf price in GBP against what the listing actually states. About £7.09 for three named plants is the lowest price in the set. About £10.00 buys the only large review sample, as one culture cup, so that price does not also take the value badge. Unreviewed title counts are not treated as plants that arrived.
Buy the species and the format before you buy the star line. Prices below are amazon.co.uk shelf prices on 19 October 2026. A pond word in a title is not a British winter trial. This is not a laboratory test.
Frogbit sold on these amazon.co.uk listings is a free-floating plant. You are choosing a live plant, not a pump, a liner or a fertiliser. Eleven titles use the name Amazon frogbit. Where a Latin name is printed, that name is Limnobium laevigatum. One listing is American frogbit, Limnobium spongia, with a bullet that leaves can reach 20 cm wide. European frogbit, Hydrocharis morsus-ranae, is the British native.
Amazon frogbit, American frogbit and European frogbit are not one plant. Nine titles here omit the species epithet. European frogbit is the native plant, and it is not in this table.
Indoor labels and an 18–30 °C care line are the listing facts. Bennetts calls Amazon frogbit not frost hardy. A pond word in the title does not change that.
A spray bar on the leaf tops is the melt UK reviews describe. A culture cup will not match a mature photograph. Do not tip trimmings down a drain or into a pond that joins a ditch.
Read the Latin name before the pack size. B07NY3TBSV and B084QF3XFQ print Limnobium laevigatum. B09D4TXY4V prints Limnobium spongia and says leaves can reach 20 cm wide, a poor fit for a small tank. Nine Live Seeds titles say Amazon frogbit or Limnobium without the species epithet. You cannot tell laevigatum from another Limnobium on those pages. The £10.00 Tropica line is a 1-2-GROW cup, part 063 TC, posted at 50 g. Rinse and float.
Leaf tops need to stay dry. Tropica and AquaPlants mark indoor use. Live Seeds state 18–30 °C, still water or gentle flow, and no splash on the leaves. Tropica's own page rates light and CO2 as low. Live Seeds say moderate to high light, and several titles say no CO2. Do not merge those into one figure. A splashing filter is the failure UK reviews describe. Bennetts and Plants for Ponds call Amazon frogbit not frost hardy. The RHS rates native frogbit H5, hardy through most of the UK.
Three typical situations, each with a recommendation from this comparison.
Indoor labels and the Tropica reviews match a still tank where leaf tops can stay dry. The Tropica 1-2-GROW cup is the top pick at about £10.00, Limnobium laevigatum, part 063 TC, with 3.9 from 97 reviews. Some plantlets rooted after a weak start. Melt, snails and a thin cup are in the same reviews.
A wildlife pond needs the native species, which is not in these twelve, or a summer plant you will lift before frost. Aquarium Fan is three Limnobium laevigatum at about £12.99. One of five reviews describes spread in a wildlife pond. The listing is still marked indoor, and Amazon frogbit is not frost hardy.
AquaPlants is three Limnobium spongia at about £7.09, the lowest shelf price for a named species sold as a stated count. A bullet says leaves can reach 20 cm wide and that the plant is not very suitable for small aquariums. There is no customer-review line, so the price is not an arrival report.
The top pick is the Tropica 1-2-GROW cup of Limnobium laevigatum at about £10.00. It names the species and amazon.co.uk shows 3.9 from 97 reviews, the only large sample here. Saved texts include plants that rooted and spread, and also melt, snails, a thin cup and deaths in a pond or in moving water. Best value is AquaPlants, three Limnobium spongia at about £7.09, because that is the lowest shelf price for a named species sold as a stated count, and the cup already holds the top score. Leaves are stated up to 20 cm wide, and there is no review line. Nine Live Seeds titles do not name the species epithet and have no reviews. None of these scores is a winter-hardiness test.
AquaPlants American frogbit, 3 plants
Lowest shelf price for a named species sold as a stated count of three plants, about £7.09.
