The types of flowers that ship well share three traits: a stem stiff enough to hold its own weight sideways, petals that bruise slowly, and enough tolerance to sit warm for an hour longer than anyone planned. Everything else in your cooler is a judgment call about risk.
That matters more than it used to. Up to 40% of all cut flowers worldwide are lost to waste somewhere between the grower and the vase, and retail spoilage alone runs anywhere from 2% to 20% of floral product (Hana Florist POS). A shop that delivers most of its orders pays that bill twice: once in dumped stems, once in the recut-and-redeliver call.
So this is a stock list built around the route, not around the display bucket. We’ll rank the workhorses, put real vase-life numbers next to them, and set the cooler temperature that protects all of it. Two neighbors cover the edges of the subject: the fragile showstoppers that hate vans get their own handling rules, and what customers actually ask for by name decides how much of each you buy.
The Bottom Line
- Durability is a property of the stem and the petal, not the packaging. Roses, carnations, chrysanthemums, alstroemeria and dry-tolerant fillers are the reliable core.
- Vase life ranges tell you where the margin is: chrysanthemum and alstroemeria run 14 to 21 days, carnation 10 to 21, standard rose 7 to 14, tulip 5 to 8 (Lacy Bird vase life guide).
- Cold does more for a flower than bubble wrap. Most non-tropical cut flowers want 32 to 35°F, ideally near 33°F (UMass Amherst Extension).
- About 80% of cut flowers sold in the US are imported, so most of your stock has already spent days in transit before it reaches you (Utah State University Extension).
- Build the stock list in three tiers: a durable core you always carry, a seasonal layer you buy to demand, and a fragile layer you sell deliberately.

What makes a flower ship well
Three things, and none of them are how pretty it is.
Stem rigidity comes first. A box or a bucket in a van turns every stem sideways at some point. A stem that holds its own head up without support survives that; a soft stem lets the head swing, and the head is the product.
Slow bruising is the second trait. Petals bruise from pressure and then show it hours later, which is the cruel part. The damage happens at your bench and surfaces at the recipient’s door. Dense, waxy or tightly packed petals forgive handling. Thin, crepe-like petals record it.
Heat tolerance is the third. Respiration speeds up as temperature rises, and the faster a flower respires the faster it burns through its own reserves (NC State Extension, “Storing Cut Flowers”). A flower that shrugs off a warm half hour in a parked van is a flower that survives a working delivery day.
Most of the choices in this guide come down to how a variety scores on those three. The ones that score well go in the cooler by default. The ones that don’t still belong in your shop, but they need a different set of handling and routing rules.
The reliable core: flowers that travel well on any route
These are the varieties you can put on a van on a Friday in July without a backup plan.
Roses have thick petals, a stiff stem and year-round availability. They are one of the traditional “big three” bestsellers in the US market alongside carnations and chrysanthemums (Utah State University Extension), and they hold that position partly because they handle a supply chain. Standard vase life runs 7 to 14 days.
Spray roses offer the same durability at a lower unit price, with smaller heads that move less inside a sleeve. Useful filler that photographs like a premium stem.
Carnations are one of the toughest things in the cooler and one of the longest-lived, at 10 to 21 days. Cheap enough to build volume with, and they tolerate handling that would mark a rose. Carnations earned a reputation as a budget flower, which is a pricing problem, not a quality one.
Chrysanthemums, in both standard and spray forms, are mechanically tough and hold shape in an arrangement for a long time, at 14 to 21 days. Mums are the variety that makes a sympathy or seasonal order safe to send across town.
Alstroemeria is light, multi-headed, resilient and very hard to damage in a box. Vase life of 14 to 21 days puts it in the same tier as mums at a fraction of the fuss.
Lisianthus gives you a rose-adjacent look with 7 to 14 days of vase life. It is less forgiving than a carnation, but it is an upgrade stem that still travels.
Cymbidium orchids are the outlier. Their waxy, substantial blooms carry a documented vase life of 21 to 42 days, the longest of anything in common use. They aren’t cheap and they need a careful pack, but they don’t collapse on a route.
Statice, gypsophila and similar dry-tolerant fillers are effectively immune to transit. They cost nothing in risk and add structure that protects softer blooms packed beside them.
Vase life by flower, and why it decides your stock list
Vase life is the number that quietly sets your waste rate. A variety with three weeks of life in it can sit through a slow Tuesday and still sell on Saturday. A variety with five days cannot.
| Flower | Vase life | Transit durability | Role in a delivery-heavy shop |
|---|---|---|---|
| Cymbidium orchid | 21-42 days | High | Premium stem, long hold, careful pack |
| Chrysanthemum | 14-21 days | High | Volume and structure, sympathy work |
| Alstroemeria | 14-21 days | High | Low-risk filler with real presence |
| Carnation | 10-21 days | High | Cheapest safe volume in the cooler |
| Rose (standard) | 7-14 days | High | The default sellable stem |
| Lily (oriental) | 7-14 days | Medium | Ship in bud, pollen is the risk |
| Lisianthus | 7-14 days | Medium | Upgrade look that still travels |
| Hydrangea | 4-10 days | Low | Short radius or hand delivery |
| Tulip | 5-8 days | Medium | Buy to order, seasonal, bends to light |
| Peony (from bud) | 5-8 days | Low | Sell in bud, deliver fast |
| Sweet pea | 4-6 days | Very low | Walk-in and events only |
Vase life ranges from Lacy Bird’s vase life guide; durability and routing notes are our own read on how each behaves on a van.
Two things fall out of that table. First, the top four rows are where a delivery business makes money, because they let you hold inventory without holding risk. Second, the bottom rows are not mistakes to avoid. They are the stems customers photograph. They just need to be sold with the route in mind.
The flowers that don’t travel well
Peony, hydrangea, dahlia and sweet pea are the famous problem children, and each fails differently.
Hydrangea drinks through its stem constantly and is very susceptible to wilting. FloraLife’s own guidance says shipping methods “should include ways of prevent excessive dehydration,” and recommends individual sleeves because the blooms are prone to mechanical damage (FloraLife). A hydrangea out of water on a warm afternoon starts going soft before the driver reaches the third stop.
Peony is a timing problem rather than a strength problem. Cut at the “marshmallow” stage it ships dry in a cooler for two to four weeks, but it is ethylene sensitive at warm temperatures, and temperature swings in transit cause condensation that invites botrytis (FloraLife). Heat opens a peony on your timetable, not the customer’s.
Dahlia has soft stems and layered petals that compress under the weight of other stems. Sweet pea is fragile and short-lived at four to six days.
None of that means dropping them. It means pricing and routing them as a different product, which is what the guide to selling the most delicate flowers works through in detail: which channels suit them, how to quote them, and how to keep a fragile order off a long multi-stop run.
What temperature should flowers be stored at?
Most non-tropical cut flowers want 32 to 35°F, ideally near 33°F, with high humidity. That range cuts respiration and water loss, which is what extends vase life (UMass Amherst Extension). Extension guidance for long-term storage lands in the same 32 to 35°F band, with 40 to 60°F acceptable only for short holds (NC State Extension).
A few varieties want it slightly warmer. FloraLife puts both hydrangea and peony at 34 to 38°F, with hydrangea humidity at 75 to 85%.
The practical point for anyone running deliveries: temperature does more damage on a route than handling does. A perfectly packed box that rides at 70°F for two hours will arrive looking worse than a roughly packed box that stayed cold. If you only fix one thing this season, fix the gap between the cooler and the van, not the tissue paper.
How demand changes what you keep in stock
Durability tells you what you can stock. Demand tells you how much.
Holiday concentration is brutal in this trade. Valentine’s Day accounts for 30% of holiday floral transactions and Mother’s Day another 26%, with Mother’s Day taking 24% of dollar volume (Society of American Florists). Two weeks of the year behave nothing like the other fifty, and the varieties that carry them are not always the ones that carry a normal Wednesday.
The full version of that argument, including how to turn named demand into a buy plan that survives a peak week, lives in the companion piece on turning popular flower demand into orders you can deliver. The short version for stock purposes: buy the durable core deep, buy the fragile layer shallow and close to the date.
A three-tier stock list that survives a delivery week
Sort everything you carry into three tiers and buy each one differently.
Tier one is the standing core: roses, spray roses, carnations, chrysanthemums, alstroemeria, plus statice or gypsophila for structure. Always in the cooler, bought deep, safe on any route. This tier should be able to produce a complete, sellable arrangement on its own, because some weeks it has to.
Tier two is the seasonal layer. Tulips in spring, sunflowers and dahlias in summer, mums and marigolds into fall, amaryllis and paperwhites at Christmas. Bought to forecast rather than to habit, in quantities you can sell inside the variety’s vase life. Buying in season also costs less, which matters when 80% of US cut flowers are imported and freight is part of the price.
Tier three is the deliberate fragile layer. Peony, hydrangea, sweet pea, garden roses, anything with crepe-paper petals. Bought shallow, sold with a conversation, and routed short. Treat this tier as a product with a service attached rather than as stock.
Then make one operational rule per tier. Tier one can go on any van on any route. Tier two goes out the same week it lands. Tier three never rides a long multi-stop route without water and a plan.
How to audit your own stock list in an hour
Pull your last four weeks of orders and your last four weeks of dumped stems, and put them side by side.
- List every variety you bought and what it cost you, in stems.
- Mark what you dumped against each one. Anything over roughly 10% loss on a tier-one variety is a cooler or ordering problem, not a flower problem.
- Mark what came back. Credits, recuts and redeliveries are the real transit score. Varieties that generate them repeatedly either need a shorter radius or a different pack.
- Check the overlap. Varieties with high loss and high complaint rates are candidates for tier three or for the drop list.
- Count your core. If tier one is fewer than five varieties, a single short delivery from a wholesaler can empty your sellable range for a day.
That audit is dull and it usually pays for itself the first time. Most shops find one or two varieties they keep buying out of habit, losing money on quietly, and defending out of affection.
Durable stems give a floral designer room to work
Buying durable stems is the floor, not the ceiling. The design decisions on top of them are the craft side of this job: what gets built in foam, what travels in water, how a recipe is written so two people build it the same way. That craft is worth learning properly if you’re building a career as a floral designer rather than just filling a cooler.
A sturdy stem gives a designer room to work. A fragile one spends that room before the build even starts.
Frequently asked questions
Which flowers last the longest in a vase?
Cymbidium orchids lead by a wide margin at 21 to 42 days. Among everyday stock, chrysanthemums and alstroemeria run 14 to 21 days and carnations 10 to 21, which makes those three the most forgiving things you can hold in a cooler (Lacy Bird).
Do flowers ship better in water or dry?
Both work, and the variety decides. Dry-packed shipping in a cold box is standard for roses, carnations and peonies in bud, because less weight and no sloshing means less mechanical damage. Thirsty varieties like hydrangea do better delivered in water on a short run.
How many flower varieties should a shop keep in stock?
Enough that your durable core alone can build a complete arrangement, which usually means five to eight tier-one varieties plus greens. Everything beyond that is seasonal or premium range rather than coverage.
Is cold storage or careful packing more important?
Cold storage, by a distance. Packing protects against pressure and vibration, but temperature governs respiration and water loss, which is what actually ends a flower’s life (NC State Extension).
The shortest version of all of this
Stock the stems that hold their own weight, bruise slowly and forgive a warm half hour, and you’ve removed most of the risk from your delivery day before a single box is packed. Keep the fragile beauties, but carry them on purpose, in smaller numbers, on shorter routes, at prices that reflect the handling they take.
Then fix the cooler. Every variety on the list above performs better at 33°F than it does at 45°F, and no amount of tissue paper buys back what heat takes.
