The best Hibiscus plants, compared.
Top pick: Generic yellow Hibiscus syriacus – Highest score in this set because the title names Hibiscus syriacus. The rosa attribute, the seed review and the missing form keep it well short of a trial. Best value: STUJYJK 1 hibiscus rhizome, variant F – The lower price for duplicate STUJYJK bullets, at £8.99, without the dried-wood reviews on the £4.15 row. Updated October 2026.
Quality starts with a species name and a form you can plant, then sun and drainage, then price. That order is the [hibiscus plant buying guide](/hub/ornamental-plants/hibiscus-plant/sub/hibiscus-plant-buying-guide). RHS rates H. syriacus H5 (hardy in most of the UK through a severe winter, about -15°C to -10°C) and H. moscheutos H4 (about -10°C to -5°C). Chinese hibiscus is tender: bright and humid, minimum nights about 7–10°C, and it must come indoors before the temperature falls below 12°C. The plant-type attribute says rosa, and one of three reviews says the parcel is seeds. A hibiscus plant in the UK is one of three different plants. Hibiscus syriacus, rose of, is a deciduous shrub, often 2.5 to 4 metres, flowering from late summer to mid-autumn. Says give rose of until July before you decide it has died. The RHS pruning group is 1, little or no pruning. A harder tidy appears in once the shrub is established, so those two instructions are not the same cut.

Personal buying guide
Question 1 of 2
Where will it spend the winter?
This generic listing is the only title in the set that says yellow Hibiscus syriacus, rose of Sharon, and the price is £14.50. The amazon.co.uk line is 3.5 stars from three reviews: one says the goods were exactly as described, and another says the parcel arrives as seeds and calls it a con. The plant-type attribute says rosa, the colour attribute says multicolour, and the bloom attribute says winter, which is not the late-summer season of rose of Sharon. Form supplied is not stated. Hardiness is only “semi-resistant winter”, not an RHS rating. It leads this table because a species appears on the title, and that lead is thin once you read the attribute and the seed review.
Pros
Cons
Best for: A shopper who will check the parcel against the title and return it if seeds arrive.
Less suitable: Anyone who needs a potted named cultivar, or who treats the winter-bloom line as a flowering calendar.
Specifications
Common questions
Does the listing name a species?
The title says yellow Hibiscus syriacus, rose of Sharon. The attribute plant type says rosa. No cultivar is named.
What do the reviews say arrived?
One review says exactly as described. Another says the package arrives as seeds and calls it a con. The star line is 3.5 from 3.
When does the listing say it blooms?
The attribute says winter. Sun and soil type are asked and not answered. Moisture is moderate watering.
The PQEWFV offer is one hibiscus rhizome at £4.15, and the amazon.co.uk line is 2.3 stars from 6 reviews. Reviewers describe a dried piece of wood in cellophane, rhizomes that were very dry, and no growth. One buyer planted the pieces and said they would update if anything appeared. The title calls it a hardy perennial that needs little or no watering, while a temperature line on the same listing says 21–29°C. Bullets also mix rhizome, bulb, and seed, and neither species nor cultivar is named. At this price you are buying a crown the reviews already call matchstick-sized and lifeless.
Pros
Cons
Best for: A buyer who already accepts a cheap unnamed crown and will return goods that arrive dead.
Less suitable: Anyone who wants a named shrub, a reliable first winter outdoors, or a plant that arrives in leaf.
Specifications
Common questions
What arrives in the parcel?
The listing says one hibiscus rhizome. A bullet also calls them bulbs, and another bullet says hibiscus seeds. The species is not named.
What do the UK reviews say?
The star line is 2.3 from 6. The review texts describe a dried piece of wood, very dry rhizomes, and no growth.
Does the listing state hours of sun?
No. Sun is not in the attributes. The title says hardy perennial and no watering required.
STUJYJK variant F is one hibiscus rhizome at £8.99, first listed on 14 August 2026, and the saved listing has no star line. The title says one rhizome, while the bullets call it a hibiscus bulbs mix for planting in the UK and mention some cold resistance. The dimensions on the listing are 25.4 × 5.08 × 6.86 cm, which describes the parcel, not a mature shrub. The same style of bullets appears on variant E at £12.07, and that higher price still does not name a cultivar. Species and hours of sun are both missing. In this set it is the cheaper of two near-duplicate singles, which is a price fact, not evidence the crown will grow.
Pros
Cons
Best for: A shopper choosing between the two STUJYJK singles and refusing to pay £12.07 for the same wording.
Less suitable: A gardener who needs Hibiscus syriacus by name, or a flat that needs a houseplant.
Specifications
Common questions
How many plants are in the pack?
The title says 1 rhizome. The plant-form line says a hibiscus bulbs mix for planting now in the UK.
Does it name the species?
No. There is no cultivar name. The variant code on the title is F.
What size is on the listing?
Product dimensions are 25.4 x 5.08 x 6.86 cm. That is the parcel size on the listing, not a mature height.
CXVGFHYG lists one hibiscus bulb at £7.79, with a first-available date of 2 June 2026 and no star line in the saved listing. The title says the plant is for the UK and also calls it a potted-plants-rhizome, so the form is not one object. One bullet says it is shade-tolerant and another says it thrives in full sun. There is no species, no cultivar, and no pot size, which leaves the indoor and garden claims as sentences rather than a plant you can site. Garden rank on the listing is 157,113. You pay more than the £4.15 rhizome for the same missing name, without the review warning that cheaper row already has.
Pros
Cons
Best for: Someone comparing unnamed single bulbs who can wait until reviews exist.
Less suitable: A patio that needs a known hardiness, or a shopper filtering by star rating.
Specifications
Common questions
Is this a potted plant?
The title says potted-plants-rhizome and 1 bulb. No pot size is stated.
What sun does the listing claim?
One bullet says it is shade-tolerant. Another says it thrives in full sun. Both lines are on the same listing.
Is there a review score?
The saved listing has no star line, so the rating is not available.
ZFGJGHK colour code A is one bulb at £9.90, sold as a hardy herbaceous perennial that is sun-loving, with a long autumn bloom and a fragrance claim on the title. The saved listing has no star line. The number-of-items attribute says 999, which does not match a title that says one bulb. Species is not named, so the herbaceous claim cannot be checked against Hibiscus moscheutos. Questions on the listing ask for planting depth, timing, and soil, and the bullets do not give those figures. Indoor beds, borders, and balcony pots are all offered, with no pot size. You pay more than the £8.99 rhizome for a habit word and a quantity field that does not add up.
Pros
Cons
Best for: A sunny border where you want a herbaceous hibiscus and will confirm the species before dispatch.
Less suitable: Anyone reading 999 as a bulk pack, or a windowsill that needs Chinese hibiscus.
Specifications
Common questions
What form is supplied?
The title says 1 bulb. The number-of-items attribute says 999, which does not match the title.
Does the listing answer planting depth?
No. The questions ask depth, timing, and soil. The bullets do not give those figures.
Where does the seller say it can grow?
Bullets say indoor and outdoor, including beds, borders, and balcony pots. The species is not named.
STUJYJK variant E is one rhizome at £12.07, and the bullets match the bulbs-mix wording on variant F at £8.99. The saved listing has no star line, no species, and no sun figure. A question on the listing asks whether it is hardy in every UK region, and the bullets only say some cold resistance. The dimensions repeat the other single, 25.4 × 5.08 × 6.86 cm, and the first-available date is 14 August 2026. The higher price does not add a cultivar, a review, or a second rhizome. If variant F is still on sale, this row is the same offer with a larger number beside it.
Pros
Cons
Best for: Only if the £8.99 variant is unavailable and you still accept an unnamed crown.
Less suitable: Anyone who can buy variant F, or who wants a named shrub in a pot.
Specifications
Common questions
How does this differ from the other STUJYJK rhizome?
The title code is E and the price is £12.07. The bullets match the bulbs-mix wording on the £8.99 variant F listing.
Is it hardy in every UK region?
The listing question asks that. The bullets only say some cold resistance. No region and no hours of sun are stated.
Is there a review score?
The saved listing has no star line.
ZFGJGHK colour code B repeats the herbaceous, sun-loving bullets of colour code A and lists one bulb at £13.39. The saved listing has no star line. The items attribute again says 999. A question about pets and children is not answered, and the species is missing, so a pet note that belongs to Hibiscus syriacus cannot be copied onto this parcel. Planting depth is asked and not given. Colour code B is a variant letter, not a cultivar such as ‘Woodbridge’. The extra £3.49 over colour code A does not buy a name, a review, or a stated pot size.
Pros
Cons
Best for: A buyer who specifically wants colour code B and has the species confirmed in writing.
Less suitable: Pet owners guessing from the word hibiscus, and anyone who can take the £9.90 listing.
Specifications
Common questions
Is it the same offer as the other ZFGJGHK bulb?
The bullets match the colour-code A listing. This title uses colour code B and the price is £13.39 rather than £9.90.
Does the listing say it is safe for pets?
A question asks about pets and children. The bullets do not answer it, and the species is not named.
How deep should it be planted?
The listing asks that question and does not give a depth.
STUJYJK variant I is two hibiscus rhizomes at £18.07, about £9 each, with the same bulbs-mix bullets as the single-rhizome rows. The unit-count attribute says 1, so the listing does not agree with its own title. The saved listing has no star line, no species, no sun figure, and no mature height. Garden rank is 124,091. You pay the highest price in this set for two unnamed crowns and a quantity field that may mean one. A pair only helps if the parcel actually contains two living crowns, which these reviews do not show because there is no star line.
Pros
Cons
Best for: Someone who wants two crowns and has checked that the seller will send two.
Less suitable: A single specimen for a pot, or a buyer who trusts the unit-count attribute over the title.
Specifications
Common questions
How many rhizomes are in the title?
The title says 2 rhizomes. The unit-count attribute says 1.
How tall do they grow?
The listing asks that and does not answer it. Sun is also not stated.
Is the species named?
No. Variant code I. The bullets match the other STUJYJK mixes.
Eight amazon.co.uk hibiscus listings were scored for this set only, not as a laboratory trial and not as a UK-wide ranking. Every row starts at 40. Points then move for a species on the title, a consistent form, a quantity that matches the title, the star line and review text, price against duplicate bullets, and hardiness or sun wording. The weights below scale those adjustments to 100. One top pick and one best value. Named nursery shrubs are outside the table.
Species on the title
25%The largest naming adjustment is +15 when the title names a species, and -5 when another field names a different plant. The £14.50 title says Hibiscus syriacus and the plant-type attribute says rosa, so both parts apply. Hardy, UK, or a flower photo is not a species.
Star line and review text
28%A star line of 3.0 or higher adds 8. Under 3.0 subtracts 12. No star line subtracts 8. Reviews that describe dried wood, no growth, or seeds instead of the titled plant subtract a further 10. Six rows in this file have no star line. A count of three or six reviews is not a trial.
Form supplied
10%One consistent form, and no seed claim, adds 8. Mixed rhizome and bulb wording, with no seed claim, adds 2. Seed also claimed, or form not stated, adds 0. A rhizome or bulb is a crown. It is not a potted shrub you can see in leaf.
Quantity match
13%The quantity attribute adds 5 when it matches the title. It subtracts 5, with no match points, when it contradicts the title, including an items field of 999 or a unit count of 1 against two rhizomes. The title quantity is what the score treats as the offer.
Price against duplicates
12%An unnamed single priced above £12 subtracts 6. An unnamed offer under £9 with no dried-wood reviews adds 6. The same style of bullets already cheaper in this set subtracts 3. That is why variant F at £8.99 is the best value against variant E at £12.07, not because a crown was grown on.
Hardiness and sun wording
12%Hardiness stated as a plant habit, such as hardy herbaceous perennial, adds 4. Some cold resistance, or for the UK, does not. Sun claims that contradict each other on the same listing subtract 5. None of these lines is an RHS H5 or H4 rating.
Start with the species, then the form that will actually arrive, then sun and drainage, then price. The notes below follow that order for this amazon.co.uk set.
A hibiscus plant in the UK is one of three different plants. Hibiscus syriacus, rose of Sharon, is a deciduous shrub, often 2.5 to 4 metres, flowering from late summer to mid-autumn. It leafs late. BBC Gardeners' World says give rose of Sharon until July before you decide it has died. The RHS pruning group is 1, little or no pruning. A harder tidy appears in Gardeners' World once the shrub is established, so those two instructions are not the same cut. RHS rates H.
A picture and the words hardy or UK do not name Hibiscus syriacus, H. moscheutos or H. rosa-sinensis. Letter codes on these titles are not cultivars.
Chinese hibiscus must come indoors before the temperature falls below 12°C. A hardy line on an unnamed rhizome is not that plant, and it is not an RHS rating for every part of the UK.
H. syriacus leafs late. BBC Gardeners' World says wait until July before you decide it has died. Cutting a woody shrub to the ground is a different mistake, and wet clay in winter is the usual failure outdoors.
Species on the label is the first check. Without it you cannot choose a winter. Hardy, UK, and a flower photo are claims, not a name. In this set only one title says Hibiscus syriacus, and the plant-type attribute on that listing says rosa, so the name still disagrees with itself. Form supplied is the second check. A potted named cultivar is a shrub you can see. A rhizome or bulb is a crown that may suit herbaceous hibiscus and may arrive dry.
Outdoor hibiscus wants full sun, shelter, and moist but well-drained soil, ideally a south- or west-facing spot. Wet clay in winter is the usual failure. RHS hardiness is the outdoor test: H5 for H. syriacus, about -15°C to -10°C, and H4 for H. moscheutos, about -10°C to -5°C. Chinese hibiscus is tender and comes indoors before 12°C. A listing that says hardy herbaceous perennial is naming a habit.
Three typical situations, each with a recommendation from this comparison.
You want rose of Sharon, Hibiscus syriacus, and you should skip tropical pots and anonymous bulbs. The only title in this set that names Hibiscus syriacus is the generic listing at £14.50. The attribute says rosa, the form is not stated, and one review says seeds arrived. Check the parcel against the title.
This amazon.co.uk set is for someone who accepts a rhizome gamble. Reviews on the cheapest row describe dry wood, no growth, and one parcel called unidentified seed. STUJYJK variant F at £8.99 is the lower price for the duplicate bulbs-mix bullets, and that file has no dried-wood reviews. It still does not name a species.
Hibiscus moscheutos dies back to a woody crown and needs a warm summer and a winter mulch. ZFGJGHK colour code A says hardy herbaceous perennial and sun-loving, at £9.90. The species is not named, and the items attribute says 999. Confirm the species before you treat the habit word as rose mallow.
The highest score in this amazon.co.uk set is the generic listing at £14.50, because the title says yellow Hibiscus syriacus. That is the top pick here only. The attribute says rosa, one of three reviews says the parcel is seeds, and the form is not stated. The best value is STUJYJK variant F at £8.99: the lower price for duplicate bulbs-mix bullets, without the dried-wood reviews on the £4.15 row. Other rows have no award. A named shrub in a nursery pot is a different product and is not in this table.
Generic yellow Hibiscus syriacus
Highest score in this set because the title names Hibiscus syriacus. The rosa attribute, the seed review and the missing form keep it well short of a trial.
STUJYJK 1 hibiscus rhizome, variant F
The lower price for duplicate STUJYJK bullets, at £8.99, without the dried-wood reviews on the £4.15 row.
