Plants and flowers are some of the most unforgiving products in the supply chain. They are living materials, not just decorative goods, which means shipping conditions directly affect respiration rate, moisture loss, appearance, and saleable life. A load can arrive on time and still be commercially disappointing if temperature, airflow, humidity, or handling were wrong during transit.
That is why plant shipping and flower shipping require more planning than many new shippers expect. Cut flowers can lose vase life quickly after a warm break in the chain. Tropicals can suffer chilling injury if they are shipped too cold. Live plants can arrive stressed, scorched, or root-damaged if temperature swings are severe.
Even the wrong co-loaded commodity can create risk if ethylene-sensitive floral freight rides beside produce that accelerates aging.
This guide explains how to ship plants and flowers across the country, what temperature ranges are common, how to prepare freight before pickup, and when reefer LTL makes sense for wholesale or distribution freight.

Flowers begin aging as soon as they are cut. Higher temperatures accelerate respiration, moisture loss, petal opening, yellowing, and eventual wilt. A short warm exposure can reduce vase life significantly, which is why cold chain discipline matters so much for wholesalers, growers, and event florists. The product may still look acceptable at delivery, but its remaining shelf life is already shorter.
Plants have a different risk profile. They are often less fragile than cut flowers in some respects, but more variable. Tropical houseplants can be damaged by cold. Nursery stock can handle different conditions depending on species and dormancy. Water-based media, tender leaves, roots, and buds all respond differently to transit stress.
In plant transportation, the right temperature is always species-specific, not generic.
Disease pressure is another issue. Warm, humid conditions can encourage Botrytis and other fungal problems in floral freight. Physical crush damage, poor airflow, and trapped moisture make the problem worse. That is one reason floral logistics requires careful packaging as well as temperature control.
Most temperate-climate cut flowers move best around 34-38 F / 1-3 C. This range slows respiration and helps preserve vase life. Roses, tulips, lilies, carnations, chrysanthemums, and many other cut varieties fit here.
The key is continuity. A short break in this range can undo the value of careful post-harvest handling.
Tropical flowers such as orchids, anthuriums, and birds of paradise generally need warmer conditions, often around 55-65 F / 13-18 C, because they can suffer chilling injury below that. Many live plants and potted tropicals also fall into a warmer protect-from-freeze or mild-temperature band.
The phrase 'keep it cold' is therefore too simplistic for plant shipping. Some products need cooling; others need protection from cold.
Nursery stock varies widely by species, maturity, and season. Some hardy plants can tolerate cooler transit; others must stay above freezing. This is why plant transportation services should be planned around the actual product profile.
For mixed loads, shippers may need to separate temperature groups rather than force all products into one compromise setting.
Pre-cooling is one of the highest-value steps in floral freight. Flowers that enter transit already stabilized at the right temperature hold quality better than flowers loaded warm and expected to cool down later. Hydration matters too. Depending on the product and packaging method, stems may need proper hydration status before loading so they do not lose condition during transit.
For plants, the water question is more nuanced. Overwatered product can create leakage, mold, and box weakness, while under-watered product may arrive stressed.
The right pre-ship moisture condition depends on species, packaging, transit length, and season.
Good packaging protects both product quality and freight integrity. Cut flowers often need upright orientation, stable palletization, and protection from crush damage.
Bouquets and event arrangements may require especially careful handling because bruising and premature opening reduce value fast. Live plants need packaging that protects foliage and containers without trapping damaging heat or moisture.
Packaging should support airflow where needed and reflect the product's physical vulnerabilities. The cheapest packaging is not always the lowest-cost choice if it increases damage claims or shortens sellable life.
One of the most overlooked details in flower shipping is ethylene exposure. Flowers are sensitive to ethylene, and some produce categories emit it as they ripen. If floral freight is co-loaded with the wrong commodities, aging can accelerate, which leads to petal drop, yellowing, and reduced vase life.
In reefer freight, commodity compatibility is part of product protection, not just temperature planning.
Parcel can work for small direct-to-consumer plant shipments, but it is usually not the right answer for palletized wholesale or retail replenishment. Standard dry LTL may be acceptable for a narrow set of hardy products in mild conditions, but it exposes freight to uncontrolled temperatures and is risky for many floral loads.
Reefer LTL is often the best plant shipping service for B2B moves when the shipment is roughly one to ten pallets and the product requires a defined temperature band. It gives the shipper access to a temperature-controlled trailer without paying for a full dedicated truck.
For growers, wholesalers, regional distributors, and event-driven shipping programs, that can be the most practical operating model.
A dedicated reefer truck becomes more attractive when the shipment is large, the product is extremely fragile, the route is urgent, or the shipper needs exclusive use of the trailer for temperature or commodity-mix reasons.
In peak floral periods such as Valentine's Day, Mother's Day, and heavy wedding-season lanes, dedicated capacity can also make sense when volume concentration is high.
Seasonality changes floral risk. Summer heat raises wilt and disease pressure. Winter raises freeze risk for live plants and some mixed floral products. Peak holidays create capacity pressure across the market, which means plant shipping companies and reefer carriers should be secured earlier than usual.
Cross-border plant shipping adds another layer because documentation may be required for plant material moving between Canada and the U.S. Operationally, the shipment still needs the same fundamentals: the right temperature, limited dwell, and fast clearance. But customs timing now becomes part of the cold chain plan as well.
For that reason, growers and wholesalers moving cross-border often need both temperature control and a brokerage-ready process.

For palletized wholesale freight, the best method is usually the one that matches the product sensitivity and shipment size. Reefer LTL is often a strong fit when plants need temperature control but the shipper does not need a full truck.
Many cut flowers ship best around 34-38 F / 1-3 C, while tropical flowers often need warmer conditions around 55-65 F / 13-18 C to avoid chilling injury.
Some hardy plants can, but many shipments are safer in temperature-controlled freight because dry trailers expose products to large temperature swings.
Pre-cooling reduces respiration and helps protect vase life. Loading warm flowers into a cold trailer is less effective than starting with a properly cooled product.
Ethylene is a plant hormone and ripening gas that can accelerate aging in flowers. Exposure during transit can increase petal drop, yellowing, and reduced vase life.
Yes. Reefer LTL is often designed for smaller palletized shipments, which makes it useful for growers, nurseries, wholesalers, and event-focused shipping programs.
