What a UK Plant Passport is
A plant passport is an official label that accompanies plants for planting as they move through the supply chain in Great Britain. It confirms that the plant has been produced and checked to meet plant health requirements, and it records enough information to trace the plant back to the business that issued the passport and the batch it came from. If a regulated pest or disease is found, inspectors use passport records to find where the rest of the batch went.
Plant passports are issued by professional operators: businesses that are registered with the plant health authority and authorised to issue passports for the plants they handle. In England and Wales that authority is the Animal and Plant Health Agency (APHA); in Scotland, registration and authorisation are handled by the Scottish Government's plant health inspectors. Authorised operators are inspected and must keep records, carry out checks on their plants and report suspected notifiable pests.
Growtropic is registered with APHA as a professional operator, and every plant we sell, from a tissue culture cup to a collector specimen, leaves the nursery with a UK Plant Passport.
Who needs to issue one: the distance-sales rule
In Great Britain, a plant passport is required when a professional operator moves plants for planting to another professional operator. Houseplants count as plants for planting: any living plant, including rooted plants, unrooted cuttings intended for growing on and tissue culture plantlets, is covered.
Sales directly to the public are usually exempt when the buyer collects in person, for instance in a garden centre. The important exception is distance selling. When a professional operator supplies plants for planting to a final user by distance contract, online, by phone or mail order, a plant passport is required. That covers most online plant shops and any business selling plants through a marketplace or social media for delivery.
This is why the presence or absence of a passport on a plant you bought online says something about the seller. A business shipping plants regularly without passports is either unregistered or ignoring the rules, and neither inspires confidence in how its plants were checked.
Operators who issue or receive passports must also keep records of them, generally for at least three years, so that a batch can be traced long after sale. A passport is therefore only as good as the records behind it, and a seller who can answer a question about where a batch came from is one whose records exist.
Reading the label: Parts A, B, C and D
A GB plant passport is a distinct label, often printed alongside the price or care label, headed with the words Plant Passport. Passports issued in Great Britain no longer carry the EU flag. It contains four elements, each marked by its letter.
- A: Botanical name. The scientific name of the plant, usually genus and species, for example Monstera deliciosa or Anthurium clarinervium. Where relevant, a cultivar may be given too. This tells inspectors which pests the plant could host.
- B: Registration number of the professional operator. The UK registration number of the business that issued the passport. This is the plant's link to a named, inspected business.
- C: Traceability code. A code identifying the specific batch, lot or consignment the plant belongs to, often a batch number, week code or barcode. It lets the operator trace the plant through its own records: where it came from, when it arrived and where the rest of the batch went.
- D: Country of origin. The country in which the plant was produced, given as a two-letter code, such as GB for plants grown in Great Britain, NL for the Netherlands or TH for Thailand.
Some plants subject to extra controls carry a protected-zone passport, marked with ZP and a code for the pest concerned. These apply to specific hosts of specific pests and are rarely seen on tropical houseplants.
Why quarantine and inspection matter
Tropical houseplants are traded globally, and they can carry pests and diseases that would be costly to UK horticulture or agriculture if they established here. Several are notifiable, meaning a suspected finding must be reported to the plant health authority. Thrips palmi, the melon thrips, and the tobacco whitefly Bemisia tabaci both attack a wide range of protected crops. The burrowing nematode Radopholus similis infests the roots of several tropical ornamentals, including Anthurium and other aroids. Xylella fastidiosa, a bacterium spread by sap-feeding insects, has hosts that include coffee plants sold as houseplants, and it is one of the most closely watched plant pathogens in Europe.
Common pests matter too, at the scale of a collection. A single plant carrying thrips or mealybug can infest a shelf within weeks. At the nursery every incoming batch goes into an isolated quarantine bay, is inspected leaf by leaf and in the root zone, and is held there under biological control until it is clean, before it joins the main glasshouse. Our approach to biological pest control continues on the benches, and you can read more about the nursery on our about page.
Imports since 2021 and personal purchases from abroad
Since 1 January 2021, plants for planting imported into Great Britain from the EU have needed a phytosanitary certificate issued by the exporting country, along with advance notification and, for many consignments, documentary, identity and physical checks. Plants from the rest of the world have long faced the same requirements, and some species are prohibited outright.
The rules apply to individuals as well as businesses. Ordering plants or cuttings from a seller abroad for delivery to a UK address, or bringing them home in luggage, generally requires a phytosanitary certificate. Plants arriving without one can be seized and destroyed. Many overseas sellers offering cheap rare cuttings through social media do not arrange certificates, and buyers who order from them take on that risk as well as the biosecurity one. Northern Ireland follows separate arrangements; this guide covers Great Britain.
How to spot uninspected or illegal imports
Warning signs when buying rare plants online:
- No plant passport on a plant supplied by a business for delivery, or a seller who does not know what one is.
- Unrooted cuttings posted from overseas in padded envelopes, sometimes described as ships from Thailand or Indonesia, with no mention of a phytosanitary certificate.
- No business name, address or registration details on the website or listing.
- Rare variegated plants offered at a fraction of the typical UK price, with vague answers about where they were grown.
- Plants arriving with live pests, eggs on leaf undersides or roots wrapped in unidentified soil.
If you have bought a plant you suspect carries a notifiable pest, keep it isolated and contact APHA's plant health service in England and Wales or the Scottish Government's plant health team in Scotland. Do not compost or bin infested material until you have taken advice.
What the passport means for you as a buyer
Keep the label, at least for the first months. If a pest problem emerges, the traceability code lets the seller identify the batch and check other plants from it. If you start selling plants yourself as a business, including regular online sales, you are likely to need to register as a professional operator and may need authorisation to issue passports; check with APHA before you start. Once a new plant has arrived, keep it apart from your collection for two to four weeks, and repot after the guarantee period into a fresh, clean substrate such as the Monstera & Philodendron Mix if it needs it.
Step-by-step protocol
- Find the passportLook for the label headed Plant Passport on the pot, stake or packing slip when the plant arrives.
- Check Part AConfirm the botanical name matches the plant you ordered.
- Note Part BRecord the registration number of the professional operator who issued the passport.
- Keep Part CPhotograph or keep the traceability code so the batch can be identified if a problem appears.
- Read Part DNote the country of origin given as a two-letter code, such as GB or NL.
- Inspect the plantCheck leaf undersides, new growth and the substrate surface with a hand lens for pests or eggs.
- Quarantine for two to four weeksKeep the plant apart from your collection and inspect weekly before it joins the others.
- Report anything unusualContact the seller with photos, and the plant health authority if you suspect a notifiable pest.
Symptoms vs root causes
| Symptom | Root cause | Action |
|---|---|---|
| No plant passport on a plant bought online from a business | Seller unregistered or not following distance-sales rules | Ask the seller for their operator registration and quarantine the plant carefully. |
| Passport shows a country of origin outside GB | Plant produced abroad and imported under certification | Nothing wrong in itself; inspect and quarantine as with any new plant. |
| Cuttings arrive from overseas with no paperwork | Likely imported without a phytosanitary certificate | Isolate the plant, inspect closely and seek advice if pests are present. |
| Unusual insects or deformed growth on a new plant | Possible pest carried in, potentially notifiable | Isolate, photograph, contact the seller and the plant health authority. |
