Mexico Crops & Crossing Flowers Into the US: CBP Rules

Yes, you can cross flowers from Mexico to the US — most cut flowers, including roses, carnations, and lilies, clear CBP inspection without incident. What you cannot cross are specific species tied to known pest and disease risks (chrysanthemums at passenger ports, orange jasmine foliage, and anything with soil attached), and every stem, declared or not, gets inspected. Mexico’s own agricultural base — tomatoes, avocados, berries, and the cut-flower trade covered below — is also the reason this checkpoint exists: the same trade volume that makes Mexican produce and flowers a fixture of US supply chains is what CBP has to screen at scale, every day, at every port of entry.

This article covers both halves of that picture: what Mexico actually grows and exports northward, and the exact rules — declaration, prohibited species, soil, fillers, permits — that determine whether your flowers, or a commercial shipment of them, make it across.

Crops of Mexico: What Actually Grows There and Ships North

Mexico is one of the United States’ largest agricultural trading partners, and the relationship runs through a narrow set of crop categories rather than general farm output. Mexican agricultural exports to the United States totaled $37 billion in 2024, according to Banco de México figures cited in the U.S. Department of Commerce’s trade barriers report on Mexico. That figure spans fresh produce (tomatoes, avocados, peppers, berries), and — the category this page focuses on — cut flowers and nursery stock.

On the flower side specifically, US horticultural imports from Mexico grew at a compound annual growth rate of 8% between 2000 and 2021, and volume roughly doubled between 2011 and 2021 following the implementation of the Food Safety Modernization Act (FSMA), per USDA Economic Research Service’s 14-year review of the trade. That growth is structural, not seasonal: it reflects Mexico’s proximity to the US market, USMCA’s zero-tariff treatment of qualifying goods (current status per the Office of the U.S. Trade Representative), and steady investment in greenhouse and shade-house production for export.

Total US imports of cut flowers, plants, and nursery stock from all countries reached $3.3 billion in 2022, per USDA ERS. Mexico is a meaningful supplier within that total, though — and this matters if you’re trying to size the Mexico-specific share — USDA’s public chart data reports absolute stem counts by country rather than Mexico’s dollar value or percentage share of the total. The closest verifiable comparison is stem volume for roses specifically, covered in the chart below.

For readers who came here searching “crops of Mexico” or “crops in Mexico” expecting a full agricultural inventory: Mexico’s major export crops to the US beyond flowers include avocados, tomatoes, peppers, cucumbers, and berries — each governed by its own USDA/APHIS phytosanitary protocol, separate from the flower rules below. If your interest is specifically in produce rather than flowers, the CBP guide on bringing agricultural products into the United States covers fruit and vegetable rules in the same framework used for flowers.

Can You Cross Flowers From Mexico to the US? The Short Answer

Crossing at a land port of entry (San Diego/Tijuana, El Paso/Juárez, Laredo, and similar crossings) or arriving by air with flowers works the same way for personal travelers: declare the flowers to the CBP officer, expect a physical inspection, and expect the flowers to be released unless they belong to a restricted species or arrive with soil attached. There is no blanket ban on crossing flowers from Mexico — the confusion online largely comes from conflating “restricted” (a short, specific list) with “prohibited generally” (not the case for the vast majority of cut flowers).

• Personal travelers: A bouquet of roses, carnations, or lilies for personal use is legal to cross after declaration and inspection.
• Commercial importers: Every commercial flower shipment from Mexico is inspected by CBP agriculture specialists — there is no sampling threshold below 100%.
• Restricted species: A small number of species (chrysanthemums at passenger ports, murraya/orange jasmine as filler) are turned away regardless of quantity, because of documented pest and disease vectors detailed in Rule 2 below.

CBP agriculture specialists nationwide intercept an average of 231 agricultural pests per day and seize roughly 3,287 prohibited items daily — plants, meat, and animal byproducts combined — according to CBP’s own newsroom release on interception statistics. Cumulatively, CBP reports having inspected 1.1 billion flower stems to date as of its most recent published release. Those numbers are the reason for the rules below, not just decoration.

Which Flowers Can You Cross From Mexico to the US

This is the practical list for the “what flowers can I cross” and “what flowers can cross the border” questions. Based on CBP’s published prohibited/restricted items guidance and the species-specific risks documented in its enforcement communications:

• Generally allowed after inspection: roses, carnations, lilies, marigolds, gladiolus, orchids, sunflowers, and most standard cut-flower species sold commercially.
• Restricted at passenger ports: chrysanthemums, because of their association with Chrysanthemum White Rust, a fungal disease with no established US foothold that CBP is actively keeping out.
• Restricted as filler/greenery: murraya (orange jasmine), because it is a known host of the Asian citrus psyllid, the insect vector for citrus greening disease (huanglongbing), which has already devastated citrus production in Florida and is a standing threat to California and Texas groves.
• Never allowed regardless of species: any flower, cutting, or plant with soil visibly attached to the roots.
• Requires a permit before travel: anything intended for planting/propagation rather than display — cuttings, bulbs, seeds, rooted plants — even of an otherwise-allowed species.

For the full current list rather than a snapshot, CBP’s Prohibited and Restricted Items page is the authoritative, continuously updated source — species get added or removed as pest situations change, so this article’s list should be treated as a starting point for the categories, not a substitute for checking before you travel.

Can I Cross Roses From Mexico to the US?

Yes. Roses are not on any CBP restricted list and are the single most common cut flower crossing the southern border by volume, alongside supply from South America. USDA ERS data for January 2023 shows roughly 1 million rose stems imported from Mexico that month, compared to 177 million stems from Colombia and 137 million from Ecuador in the same period — Mexico is a real but minor source of US roses relative to the two South American giants that dominate the Valentine’s Day and Mother’s Day trade. Every rose shipment, regardless of country of origin, is still inspected on arrival: CBP checks for aphids, spider mites, thrips, and fungal leaf disease before release, exactly as it would for any other allowed species.

Practically, this means a personal traveler crossing with a rose bouquet from Tijuana or Ciudad Juárez faces the same declaration-and-inspection process as any other allowed flower — there’s no rose-specific paperwork. A commercial importer bringing in rose shipments at volume, by contrast, is working within the broader Colombia/Ecuador-dominated import market and should expect CBP scrutiny calibrated to that larger trade, not a Mexico-specific process.

Importing Flowers to the US: The Commercial Pipeline

Commercial flower importers face a different — and heavier — compliance load than personal travelers. Every shipment is inspected, not sampled, and USDA/APHIS phytosanitary certification requirements sit on top of the CBP border inspection described throughout this article. Three factors specific to commercial import are worth naming clearly:

• USMCA tariff treatment: Flower imports from Mexico that qualify under USMCA rules of origin currently enter at a 0% tariff, per the Office of the U.S. Trade Representative’s trade agreement terms. This is a standing policy as of this review, not a permanent guarantee — USTR.gov’s trade agreement tracker is the place to confirm current tariff status and rule-of-origin certification requirements before relying on it for a shipment plan, since tariff suspensions or modifications can be announced at any time.
• Volume context: Mexico’s horticultural export volume to the US has grown at an 8% compound annual rate from 2000-2021 and doubled from 2011-2021, per USDA ERS — a commercial importer entering this trade is joining a growing, not shrinking, supply chain.
• What’s not publicly published: USDA does not publish a Mexico-specific dollar value for flower imports (only the $3.3 billion all-country total), nor a public breakdown of what share of Mexican flower shipments require phytosanitary treatment versus inspection-only clearance, nor a count of APHIS-certified Mexican flower exporters. Importers who need these figures for underwriting or sourcing decisions should request them directly from USDA APHIS or from a licensed customs broker with Mexico flower experience — they are not in any public USDA or CBP release as of this review.

7 CBP Rules for Crossing Flowers and Plants From Mexico

The rules below apply to both personal travelers and commercial importers, scaled to volume. Each one reflects an actual, documented CBP enforcement priority — not a hypothetical risk.

1. Always Declare Flowers and Plants at Customs

Every plant, flower, and agricultural product must be declared to CBP officers on arrival — this is the single non-negotiable rule underlying everything else. Declaration routes the item to the correct inspection lane; failure to declare converts a routine inspection into a potential civil or criminal penalty, plus seizure of the material regardless of whether it would have passed inspection anyway. Declaring an allowed flower costs you nothing but a few minutes; not declaring a restricted one costs you the shipment and a fine.

2. Know Which Flowers and Plants are Prohibited or Restricted

The restricted list is short and specific, not broad:

• Chrysanthemum: restricted at passenger ports when brought from Mexico, due to its role as a carrier of Chrysanthemum White Rust, a fungal disease that damages US flower production if it establishes.
• Murraya (Orange Jasmine): a common bouquet filler that hosts the Asian citrus psyllid, the insect vector for citrus greening disease — a direct threat to US citrus growers in Florida, California, and Texas.
• Plants for growing, not display: cuttings, bulbs, and rooted plants require permits obtained before travel, regardless of species.

The CBP Agricultural Products Guide is the primary reference to check before travel, since species can be added to or removed from restricted status as pest situations evolve.

Summary Table: CBP Flower Import Restrictions from Mexico

Note the last column pattern across the table: allowed species are only ever seized if inspection finds an actual problem, while restricted species are seized on identification alone, regardless of condition. That distinction is the whole rulebook in one sentence.

3. Understand Soil Import Regulations

No soil attached to roots or included in packaging is permitted, for any species, allowed or restricted. Soil is a carrier for pests and disease agents invisible to a visual check — insect eggs, fungal spores, nematodes — which is exactly why CBP treats it as an automatic red flag rather than something to inspect and clear. Even plants intended for growing must arrive soil-free unless accompanied by pre-arranged USDA permits. Wash and wrap roots and stems before travel; violations result in disposal of the material and possible penalties on top of losing the flowers.

Every commercial flower shipment from Mexico is inspected by CBP — there is no sampling threshold, per CBP’s published interception program.

4. Be Aware of Pests and Invasive Species Threats

CBP agriculture specialists physically shake flowers and use magnifying tools to find insects or disease symptoms that aren’t visible at a glance. Nationwide, this process catches an average of 231 agricultural pests per day, and CBP has inspected 1.1 billion flower stems cumulatively as of its most recent published figures — both from CBP’s own newsroom release on the program. Suspicious material gets forwarded to USDA specialists for identification before a shipment is cleared or destroyed. This is the operational reality behind “why does this take so long at the border”: it’s a per-stem physical check, not a document review.

5. Bouquet Fillers and Greenery are Carefully Inspected

Fillers and greenery get the same scrutiny as the primary flowers, sometimes more, because they’re easy to overlook. Murraya (orange jasmine) is checked specifically for Asian citrus psyllid; if any component of a mixed bouquet is found infested, CBP can seize the entire arrangement rather than just the offending stem. Eucalyptus, ferns, and myrtle — common fillers — also draw inspection attention for the same reason: a bouquet is only as clean as its least-checked ingredient.

6. Inspections are Thorough and Technology-Driven

The inspection sequence runs: physical examination (shaking, checking stems and petals) → magnifying-tool inspection for small insects or disease signs → transfer of suspicious samples to USDA specialists for identification and digital imagery analysis → in rare high-risk cases, laboratory confirmation. This layered process is how CBP sustains the 231-pest-per-day interception rate cited above without physically destroying every shipment that passes through — most flowers clear the first two stages and move on.

7. Permits for Growing Plants: What’s Required?

Plants brought for growing — seeds, cuttings, saplings, bulbs — need USDA and CBP permits obtained before entry, not at the border. Requirements: permits secured prior to travel, plants soil-free or compliant with the soil rules above, and documentation tracing origin and pest-free status. Anything arriving without prior permits is halted, and typically destroyed or re-exported rather than held pending paperwork. If you’re planning to propagate rather than display, start the permit process weeks before travel, not at the crossing.

Assumptions: this reflects the general rules described in this article as of the review date above and does not replace an actual CBP officer’s determination, which accounts for real-time pest alerts and shipment-specific findings. It excludes commercial-volume phytosanitary certificate requirements — commercial importers should confirm current requirements with USDA APHIS or a customs broker.

Practical Tips for Crossing the Border with Flowers

• Check the current list before you travel: consult CBP’s Know Before You Go guide, since restricted species can change.
• Clean before you pack: remove all soil, snip unhealthy leaves, and inspect for visible insects.
• Declare everything: tell the CBP officer what you’re carrying — this is the single biggest factor in a smooth crossing.
• Don’t gamble on fillers: undeclared or unidentified greenery risks the whole bouquet being confiscated.
• Ask if unsure: CBP and USDA staff handle pre-clearance questions and publish current guidance online.

Conclusion

The rules covered here don’t change often, but the specifics — which species are restricted, current tariff treatment, published interception figures — do get updated by CBP and USDA on their own schedules. Treat this article as the framework: declare everything, keep roots soil-free, check the current restricted list before you travel, and get permits ahead of time for anything meant for growing rather than display. For the figures that move (tariffs, interception rates, source-country volumes), the CBP and USDA ERS links throughout this article are the sources to re-check rather than relying on a fixed number indefinitely.
