Everything you approve travels through one warehouse

South Florida is not simply near the flower trade; it is the trade's front door. U.S. Customs and Border Protection reports that Miami receives more than 91% of the cut flowers arriving from South America, with Los Angeles a distant second. In the weeks before Valentine's Day 2026, agricultural specialists at Miami International Airport were set to process roughly 990 million stems, arriving mostly from Colombia and Ecuador on hundreds of flights.

That concentration is an advantage — variety, volume, and short transit times you cannot get anywhere else in the country — and it is also a single point of exposure. Between the farm and your ceremony, a stem passes through farm allocation, air cargo, customs clearance, a wholesaler's cooler, and a designer's bench. Each link can alter the count, the grade, or the arrival date without altering anyone's good intentions.

Inspection is a real variable, not a formality. Cut flowers are a regulated commodity: 7 CFR Part 319, Subpart P governs their entry, and it is explicit that shipments failing the applicable conditions are refused entry. USDA's Animal and Plant Health Inspection Service maintains the commodity-by-commodity requirements behind that rule, and notes that requirements can change over time or when a pest or disease outbreak occurs in a source country. A pest interception on a Tuesday can quietly reshape what is available on a Thursday.

Why 2026 changed the math on origin

For more than a decade, Colombian flowers entered duty-free under the U.S.–Colombia Trade Promotion Agreement, and origin was a horticultural question rather than a pricing one. That ended. USDA's Foreign Agricultural Service describes Colombia's $2.4 billion cut-flower sector as supplying roughly 60% of the flowers sold in the United States, with nearly 80% of Colombian production aimed at the American market — and records the 10% duty imposed in April 2025 as the first U.S. tariff on Colombian flowers in over a decade.

Since then the legal basis has moved twice. The Supreme Court struck down the IEEPA tariffs in February 2026, and the administration replaced them within hours with a temporary 10% surcharge under Section 122 of the Trade Act of 1974 — an authority capped at 150 days, which set a hard expiry of July 24, 2026. On that same date, a new tranche took its place: the U.S. Trade Representative's Section 301 forced-labor action imposed additional duties of 10% or 12.5% on products of 60 investigated economies, subject to exemptions listed in Annexes I and II. Colombia sits in the 12.5% band; Ecuador sits in the 10% band, with country-specific carve-outs that trade reporting indicates cover roses and other fresh flowers. Separately, the U.S.–Ecuador Agreement on Reciprocal Trade, signed 13 March 2026, keys its tariff provisions to August 1, 2026 or the date of entry into force, whichever is later.

The practical takeaway is not a number. It is that two origins that were once interchangeable on price can now diverge — and that the divergence is subject to change on a schedule nobody controls.

Nothing here is legal, tax, or customs advice. Tariff classification and duty liability rest with the importer of record, and rates and exemptions change; confirm current treatment with a licensed customs broker, and have contract language reviewed by a Florida-licensed attorney.

How to write a palette as a range

A range is more specific than a list, not less. A list names five flowers and says nothing about why. A range describes the design so precisely that a competent designer can hit it with different material. Five parameters do most of the work:

• Hue band, not a hue. "Warm blush through soft terracotta, nothing with a blue undertone." Anchor it to something physical both sides can hold — a fabric swatch, a paint chip, or an RHS Colour Chart code — because "dusty rose" means four different things to four vendors.
• Value and saturation. Whether the arrangement reads pale and washed or deep and saturated matters more to a photograph than the species does.
• Form and rhythm. Spikes, discs, rounds, spray, and airy filler in stated proportions. This is what makes a substitution invisible: swap a disc for a disc and the silhouette survives.
• Scale and finish. Head diameter, stem length, and whether the surface should look matte and garden-grown or waxy and formal.
• Movement. Tight and architectural, or loose with reaching stems. Two arrangements with identical flowers can fail this and look wrong.

Then rank, in writing, three tiers: two or three hero elements that are genuinely non-negotiable and worth paying to protect; a supporting band where any flower meeting the hue-and-form spec is pre-approved; and a texture band left entirely to the designer. Most couples discover, once forced to rank, that only the bridal bouquet and one installation carry real emotional weight. Everything else was preference wearing the costume of a requirement. That conversation belongs in floral design planning sessions, not in a panicked phone call the week of the event.

The substitution clause, written properly

Most substitution clauses are one sentence long and protect nobody, because they grant permission without defining limits. A clause that actually works answers seven questions:

1. Trigger. What conditions permit substitution — unavailability, quality below a stated grade, delayed clearance, freight disruption?
2. Authority and tier. Who decides, and within which pre-approved band? Hero items should require a call; texture items should not.
3. Value floor. Substitutes must be of equal or greater wholesale value. This is the sentence that stops "substitution" from meaning "downgrade."
4. Price mechanism. If the substitute costs more, who absorbs the delta, and up to what threshold before approval is required?
5. Duty and freight movement. Whether landed-cost changes are passed through, capped, or held — agreed before signature, not after a Federal Register notice.
6. Notice and window. How the client is notified, and how long they have to respond before the designer proceeds by default. A 48-hour approval window is worthless if the flowers are already in the cooler.
7. Documentation. A photograph of the substitute against the reference swatch, filed before install.

Those seven questions are decisions, not paperwork, and they are best resolved alongside the rest of the timeline with your planning team while there is still time to change the design instead of defend it.

Temperature is the variable nobody negotiates — and it decides how the flowers look at 9 p.m.

Cold chain, not species, determines whether an arrangement holds through a South Florida reception. USDA's Agriculture Handbook 66 remains the reference on storage conditions, ethylene sensitivity, and chilling injury for florist stocks, and its central point is unglamorous: low temperature suppresses respiration and ethylene production, which is what buys vase life.

The trap is that "colder is better" is false for exactly the flowers Miami clients love. A postharvest review in Ornamental Horticulture notes that chilling-sensitive species — bird-of-paradise, heliconia, orchid, ginger — cannot be held below roughly 10 to 13 °C without tissue discoloration. Put a tropical installation in the same cooler as roses for two days and it will show up bruised and browning with no visible cause. If your design mixes temperate and tropical material, it needs two holding environments and a staged install order, which is a production question rather than a design one.

The same logic governs the venue. Outdoor ceremonies in Broward, Miami-Dade, and Palm Beach counties compress the safe window between install and first look. Practical controls that cost nothing to specify in advance: hydrate everything in a shaded staging area rather than at the site; schedule delicate installations last; keep arrangements away from ripening fruit at cocktail hour, since ethylene is indifferent to how much the flowers cost; and set an honest install call time instead of an optimistic one.

Calendar risk in a market fed through one airport

Two dates dominate the supply chain, and neither is a wedding. Farms plan production and airlines allocate capacity around Valentine's Day and Mother's Day; a Miami-area event within roughly three weeks of either is competing directly with the largest floral consumption periods in the country for the same stems, the same freight, and the same processing labor. Longer lead times and a wider approved band are not caution in that window — they are the only mechanism that works.

The second date is meteorological. NOAA notes that the Atlantic hurricane season runs from June 1 to November 30, peaking on September 10, with most activity between mid-August and mid-October. That window affects air cargo into Miami as much as it affects tenting and outdoor ceremonies. Autumn events benefit from a documented alternate-material plan and a decision, made early, about which elements can be built from preserved or dried material. Worth noting for anyone specifying that route: the federal cut-flower rules are written for fresh product, and the regulation's own definition excludes dried, bleached, dyed, or chemically treated decorative plant material — different category, different handling, different lead time.

Frequently asked questions

Doesn't a substitution clause just let the florist give me cheaper flowers?

Only if it is written badly. A clause with an equal-or-greater-value floor, ranked tiers, and photographic documentation gives you more protection than a rigid list does, because a rigid list has exactly one failure mode: something arrives that was never approved, on the morning of the event, with no time to discuss it.

If duties change between my contract date and my event, who pays?

Whatever your contract says — which is why it should say something. Duty treatment moved several times between early 2025 and mid-2026, and a contract silent on landed-cost changes turns a policy shift into an argument. Agree on a pass-through rule, a cap, or a fixed price with a stated tolerance band at signature.

Are Ecuadorian roses now cheaper than Colombian ones?

Origin economics shifted in 2026, and the Section 301 action treats the two countries differently. But wholesale pricing also reflects variety, grade, stem length, freight, and season, so the duty line is one input among several. Ask your designer what is currently landing well rather than specifying a country.

Can we just use locally grown Florida flowers instead?

For some elements, genuinely yes — foliage, tropicals, and certain seasonal specialties. For volume roses in a specific hue at a specific grade, the domestic supply is not structured to replace imports, which is precisely why 90% of the country's imported stems come through Miami. A mixed sourcing plan is realistic; a fully local one usually means redesigning the palette, which is a fine choice if made deliberately.

How far ahead should the palette be locked?

Lock the intent early and the varieties late. The hue band, form proportions, and hero items should be settled months out; final variety selection is better made close enough to the event that the designer is choosing from what is actually in the market.

What should I bring to the floral design meeting?

A physical color reference, photographs of arrangements you dislike as well as ones you love, the venue's install-access constraints and load-in times, and an honest ranking of which three floral moments matter most. That last item does more for the outcome than any inspiration board.

The decision

A list is a promise that a global supply chain never agreed to keep. A range is an instruction it can follow. Name the feeling and the finish, band the color, rank what is untouchable, pre-approve what is not, and put the substitution rules in writing while everyone is calm. Do that, and the question on the morning of your event stops being "did we get the flowers we asked for" and becomes the only one that ever mattered: does the room look the way we meant it to.
