Most people have never thought about the journey a cut flower takes before reaching a vase. It is a more complex journey than the product suggests — often spanning continents, refrigerated warehouses, air freight, and auction floors, compressed into a matter of days because the product is perishable.

Understanding that system makes for better buying decisions, and it clarifies which environmental claims are meaningful and which are decorative.

How the Global Flower Trade Works

The cut flower industry is genuinely international. Major growing regions include the Netherlands, Colombia, Ecuador, Kenya, and Ethiopia, alongside significant domestic production in Canada and the United States.

These regions exist as flower producers for specific reasons: consistent climate, appropriate altitude, available labour, and established logistics. Ecuador's high-altitude equatorial conditions produce roses with notably large heads and long stems. Colombia dominates carnation and chrysanthemum production. Kenya supplies much of Europe's rose volume.

Flowers move through this system fast. Cut, graded, cooled, packed, flown, cleared, distributed, and sold — often within a week. The cold chain is what makes it possible, and breaks in that chain are the main cause of poor vase life.

The Ontario Growing Season

Canada has genuine domestic production, split between field-grown seasonal flowers and year-round greenhouse growing.

Ontario's field season runs roughly May through October, and it produces some of the most interesting material available anywhere.

Late spring brings tulips, ranunculus, lilac, flowering branches, and the brief and much-anticipated peony window.

Summer delivers snapdragons, lisianthus, sweet peas, delphinium, zinnias, sunflowers, garden roses, and an expanding range of specialty varieties.

Late summer and autumn belong to dahlias above all, alongside amaranthus, celosia, chrysanthemums, grasses, and berried branches.

Greenhouse production extends the range considerably, supplying gerbera, chrysanthemums, roses, and potted plants year-round.

What local field production offers that imports generally cannot is a category of flower that does not travel well. Sweet peas, garden roses, poppies, and cosmos are too delicate for long-haul freight. If you have only seen them at a market in July, that is why.

What "Sustainable" Actually Means Here

The term is used loosely, so it helps to separate the components.

Transport

Air freight has a real carbon cost. But the comparison is not always as simple as local-versus-imported, because heated greenhouse production in a cold climate also carries substantial energy costs. A flower grown in Ontario in February under heat and light may not have a lower footprint than one grown in equatorial sunlight and flown in.

The clearer conclusion is about seasonality rather than distance: flowers grown in their natural season, wherever that is, generally carry lower impact than flowers forced out of season anywhere.

Growing practices

Water use, pesticide application, and soil management vary enormously between operations. Several international certification schemes address labour and environmental standards in flower production, and their presence is a meaningful signal.

Floral foam

Conventional floral foam is a non-biodegradable plastic that breaks down into microplastics. A growing number of florists have moved to foam-free mechanics — chicken wire, moss, reusable armatures, and structural stem work. This is one of the more concrete and verifiable sustainability shifts in the trade.

Waste and packaging

Cellophane wrap, plastic sleeves, and single-use containers all add up. Reusable vessels, paper wrap, and compostable materials are increasingly standard.

Labour

Often overlooked in environmental conversations and genuinely important. Flower growing is labour-intensive, and certification schemes addressing wages and working conditions matter as much as those addressing pesticide use.

Practical Choices for Buyers

You do not need to audit a supply chain to buy better. A few habits do most of the work.

Ask what is in season. This single question steers you toward flowers that are fresher, cheaper, and lower-impact simultaneously.

Ask where things come from. A supplier who can answer is a supplier paying attention. Vagueness is itself informative.

Prioritize vase life. The most wasteful flower is one that dies in three days. Durable, well-handled stems reduce waste more effectively than any label.

Ask about foam. It is a simple, specific question with a clear answer.

Accept substitutions. Insisting on an exact variety out of season forces sourcing decisions that are worse on every dimension. Specifying colour and mood instead gives a florist room to use the best available material.

Consider plants for longevity. A flowering plant that lasts months does a different job from a bouquet and has a very different footprint.

Buying from a local business also keeps the chain shorter at its final stage. A Toronto flower delivery service sourcing regionally in season and handling stems in a proper cold chain reduces both waste and the transport that happens after wholesale — the part of the journey most consumers never see.

Being Honest About Trade-Offs

There is no version of the cut flower industry with zero impact. Flowers are perishable, refrigerated, and frequently travel. Anyone claiming otherwise is overselling.

There are, however, meaningfully better and worse choices. Seasonal beats forced. Foam-free beats foam. Certified beats unverified. Long-lasting beats short-lived. Regional production, in season, beats out-of-season anything.

The Case for Knowing More

Flowers are among the few products people buy purely for pleasure. That makes it easy to avoid thinking about their origins, and slightly uncomfortable to start.

But the knowledge is genuinely rewarding rather than burdensome. Learning that lilac has a three-week window, or that sweet peas cannot be shipped far, or that dahlias arrive just as everything else is finishing — this makes flowers more interesting, not less.

It also makes them better. The most beautiful arrangement available in any given week is almost always the one built from what is actually thriving at that moment, close by. Paying attention to where flowers come from turns out to be the same thing as paying attention to what is best.
