Can You Bring Flowers From Mexico to the US? Rules and Fines

You can bring flowers from Mexico to the US, and most common bouquets clear the border without trouble, but every stem has to be inspected by a CBP agriculture specialist and a few varieties are banned outright.¹ Roses and carnations are fine. Chrysanthemums are not. Anything with soil or roots is not. And whatever you’re carrying, you have to declare it, because failing to do so can cost you up to $1,000 and your Global Entry membership.

Which Flowers Are Allowed

There is no blanket ban on fresh flowers from Mexico. Roses, carnations, and many other fresh cut varieties can enter the country as long as a CBP agriculture specialist inspects them and finds no pests or disease.¹ Inspection is mandatory. You have to present the flowers to a specialist at the first port of entry, and if any part of a bouquet is infested or otherwise fails to meet entry requirements, the whole bouquet is refused.² A single infested filler stem sinks the whole arrangement.

Which Flowers Are Prohibited

Chrysanthemums from Mexico are prohibited at passenger ports of entry. They can carry Chrysanthemum White Rust, a fungal disease that would do serious damage to commercial flower growers in the US.¹ This trips up more travelers than any other rule, because chrysanthemums are sold everywhere in Mexico and they’re cheap.

Watch the greenery in a mixed bouquet, too. Murraya, sometimes called orange jasmine, is banned because it hosts the Asian citrus psyllid, the insect that spreads citrus greening disease. Any cut greenery used as filler may be prohibited if it poses a risk of carrying plant diseases, invasive insects, or parasitic nematodes.³

Soil is prohibited in any form. Potted plants, flowers with root balls, and arrangements sitting in dirt or any other growing medium cannot enter the country without a USDA permit or an approved soil treatment.⁴ If it has roots or dirt, leave it in Mexico.

Plants protected under the Endangered Species Act or CITES, which can include some orchids, cacti, and cycads sold as ornamentals, have their own permit requirements from the US Fish and Wildlife Service on top of anything APHIS requires.⁵

Dried and Artificial Are the Safe Choice

Dried, bleached, dyed, or chemically treated decorative plant materials are not classified as fresh cut flowers and generally pose far less biological risk.⁶ Artificial flowers made from fabric, plastic, or other synthetic materials are also fine. Both may still be looked at briefly to confirm they aren’t hiding fresh plant material or pests. If you want a bouquet you know will make it across, this is the category to shop in.

Bringing Live Plants or Seeds

Live plants meant for growing are a different situation from cut flowers, and the rules get stricter. Travelers may bring up to 12 bare-rooted plants (no soil, sand, or growing media at all) if the plants meet two conditions:

A phytosanitary certificate issued by Mexico’s National Plant Protection Organization confirms the plants are free of pests and disease.
The plants are not prohibited, not protected under the Endangered Species Act or CITES, and not subject to special restrictions like post-entry quarantine.

Anyone bringing 13 or more plants needs an import permit from APHIS and has to ship the plants directly to the nearest USDA Plant Inspection Station.²

Seeds run on their own rules. Small quantities of admissible herbaceous plant seeds can come in under a Small Lots of Seed permit (PPQ 587), which caps each packet at 50 seeds or 10 grams and each shipment at 50 packets. Seeds have to be free of pesticides, labeled with the scientific name and country of origin, and shipped to the APHIS Plant Inspection Station named on the permit. Seeds of federal noxious weeds, parasitic plants, and seeds coated in growing media are not eligible.⁷

Declaring Flowers at the Border

Every traveler entering the United States has to declare all agricultural products, flowers included, whether crossing at a land port, arriving by air, or coming by sea.⁸ Check “Yes” on the customs declaration form, or tell the officer directly. Declare everything, including items you think are allowed and items you’re not sure about.

Here’s the part most people don’t realize: as long as you declare, there is no penalty even if the inspector decides the flowers can’t come in.⁸ The flowers get confiscated and destroyed, and you walk away. Declaration protects you. The fines only come when you don’t declare and CBP finds the flowers anyway.

What You Pay If You Don’t Declare

Undeclared agricultural items trigger civil penalties under the Plant Protection Act. For a first-time, non-commercial violation by an individual, the maximum fine is $1,000, and in practice CBP commonly assesses $500 for a first offense. Repeat or more serious violations can run up to $50,000 per individual, and willful violations adjudicated together can reach $1,000,000.⁹ The undeclared items are confiscated and destroyed either way. Declared items that turn out to be prohibited can simply be abandoned at the port of entry with no penalty attached.¹⁰

Trusted Traveler Consequences

If you’re enrolled in Global Entry, SENTRI, or NEXUS, an undeclared bouquet can cost you far more than the fine. CBP records released through FOIA requests show that members who fail to declare prohibited agricultural items routinely have their trusted traveler membership revoked, often permanently, even on a first offense. The typical outcome is a $500 civil penalty and immediate revocation.¹¹

Losing Global Entry also means losing TSA PreCheck benefits unless you paid for PreCheck separately. You can appeal through the Trusted Traveler Programs website, but successful reinstatements after an agricultural violation are rare. A $15 bouquet you forgot to mention can cost you years of expedited crossings.

How to Check Before You Cross

Instead of guessing at the border, look up specific flowers and plants ahead of time. USDA runs the Agricultural Commodity Import Requirements (ACIR) database, which lets you search by commodity and country of origin to see whether an item is admissible.² The database is at acir.aphis.usda.gov. For questions about protected species or unusual plants, APHIS runs a Plant Import Information Line at 877-770-5990 and takes email at plantproducts.permits@usda.gov.

For most travelers, the practical rule is short. Stick to common cut flowers like roses and carnations. Skip the chrysanthemums. Nothing with roots or soil. Declare whatever you carry. Do those four things and the bouquet will almost certainly make it home with you.
