What a Floral Case Is and How Florists Use Them

A floral case is a refrigerated display cabinet that holds cut flowers at the temperature and humidity they need to stay fresh

Florists use floral cases to keep arrangements, bouquets, and individual stems in the right conditions between the time they arrive from growers and the moment a customer takes them home. The case maintains cool temperatures—usually between 34 and 40 degrees Fahrenheit—and holds moisture in the air so petals don't dry out or wilt. Without one, flowers would deteriorate in hours, especially in warm South Carolina weather.

When you walk into a florist shop, the flowers you see displayed behind glass are sitting in a floral case. The case protects the inventory and lets customers see what's available without handling the stems. Most cases have glass doors or sides so the flowers remain visible while staying sealed inside the controlled environment.

Key Takeaways

• Floral cases are refrigerated cabinets that keep cut flowers fresh by maintaining cool temperatures and humidity levels.
• Florists rely on cases to store inventory between delivery and sale, extending the life of stems by days.
• The glass design lets customers browse arrangements while the sealed environment protects flowers from heat and air exposure.
• South Carolina's warm climate makes floral cases essential for any florist operating year-round.

Why florists need refrigeration for cut flowers

Cut flowers are living tissue. Once separated from the plant's root system, they begin to lose water and nutrients. Heat speeds up this process dramatically. In a warm room, a rose can wilt noticeably within hours; in a floral case, the same rose can stay fresh for a week or more.

The cool temperature slows the flower's metabolism, reducing water loss and delaying the breakdown of cell walls that causes wilting. Humidity in the case prevents petals from drying out and becoming papery. Together, these conditions let florists hold inventory longer, fulfill orders placed days in advance, and reduce waste from flowers that spoil before sale.

Types of floral cases florists choose

Florists select cases based on the volume of flowers they stock and the space available in their shop. A small neighborhood florist might use a single upright case with glass doors on the front. A larger operation or one that handles many wedding orders might have multiple cases, including reach-in models (where the florist opens a door to grab stems) and walk-in coolers (where the florist steps inside to work).

Cases also vary in how they're positioned. Horizontal cases with angled glass tops let customers see arrangements from above while the flowers stay cool. Vertical cases with front-facing glass are common in shops with limited floor space. Some florists use a combination—a display case customers see from the shop floor, plus a work cooler in the back where they prepare arrangements before moving them to the display case.

How temperature and humidity work together

A floral case does more than just chill flowers. It maintains a specific humidity level, usually between 80 and 95 percent. This high moisture content keeps the air around the flowers saturated, so water doesn't evaporate from petals and leaves as quickly as it would in a dry room.

The combination of cool temperature and high humidity creates an environment where flowers age much more slowly than they would on a kitchen counter or even in a regular refrigerator. A regular fridge is too dry for flowers because it's designed to remove moisture from food. A floral case adds moisture back, creating the ideal balance for cut stems.

What flowers need before they go into the case

Florists don't simply place flowers directly into a case. When stems arrive from a grower or wholesaler, they've been traveling for hours or days. The florist first cuts the bottom of each stem at an angle to increase the surface area for water absorption, removes leaves that would sit below the waterline (where they'd rot and contaminate the water), and places the stems in a bucket of water mixed with flower food.

Flower food contains sugar for energy, an acidifier to help the stem absorb water, and a biocide to prevent bacterial growth in the water. After a few hours in this conditioning bucket—sometimes overnight—the flowers are fully hydrated and ready to be arranged or stored in the floral case. This preparation step is what allows flowers to last as long as they do once they're in the case.

How long flowers last in a floral case

The lifespan of cut flowers depends on the variety. Roses, carnations, and chrysanthemums can last two to three weeks in a floral case if they're properly conditioned and the water is changed every few days. Tulips, lilies, and hydrangeas typically last one to two weeks. Delicate flowers like orchids and gardenias may last longer because they're naturally more durable, while soft flowers like peonies and ranunculus have shorter windows.

Even in a floral case, flowers continue to age. Petals may brown at the edges, stems may develop a slight bend, or blooms may open fully and begin to shed pollen. A good florist monitors inventory and rotates stock, using older flowers first and moving newer shipments to the back. This practice ensures that customers receive the freshest possible arrangements.

The role of floral cases in South Carolina shops

South Carolina's heat and humidity create a unique challenge for florists. Outdoor temperatures regularly exceed 85 degrees in spring and summer, and the air is already humid. Without a floral case, flowers would wilt rapidly, especially during the afternoon. A case becomes not just a convenience but a necessity for any florist that wants to keep inventory fresh through the day and fulfill same-day or next-day orders.

Florists in Charleston, Columbia, Greenville, and other South Carolina cities depend on floral cases to operate reliably year-round. The case protects flowers from the shock of moving between the cool shop interior and the hot outdoor air when customers carry arrangements to their cars. It also allows florists to display seasonal flowers—like poinsettias in winter or sunflowers in summer—without them deteriorating before they're sold.

Frequently Asked Questions

Can I keep cut flowers fresh at home without a floral case?

Yes, but they won't last as long. Keep stems in a clean vase with fresh water and flower food, away from direct sunlight, heat sources, and ripening fruit. Change the water every two to three days and re-cut the stems. Flowers will typically last a week or more, though not as long as they would in a florist's refrigerated case.

Why do flowers from a florist last longer than flowers from a grocery store?

Florists condition their flowers carefully, use floral cases to store them at ideal temperatures, and change the water regularly. Grocery store flowers often sit in warm aisles, may not be conditioned properly, and sometimes spend days in transit before reaching the shelf. The combination of better handling and refrigeration makes florist flowers last significantly longer.

Do all florists have floral cases?

Most established florists do, because a case is essential for keeping inventory fresh and meeting customer expectations. Very small operations or pop-up florists might work around a case by ordering smaller quantities more frequently, but they'll have limited ability to hold flowers for future orders or keep arrangements on display.

What happens to flowers if a floral case breaks down?

Flowers begin to deteriorate quickly once the case stops cooling and maintaining humidity. A florist with a broken case will typically move flowers to a regular refrigerator temporarily, though this is not ideal. Most florists have a repair service on speed dial and consider a broken case an emergency because inventory can be lost within hours.
