Fresh cut flowers and Chilly Winter Temperatures

The Chilling Truth: How Below-Freezing Temperatures Impact Fresh Cut Flowers and What Florists Do About It

Fresh cut flowers are delicate creations of nature that bring beauty, joy, and emotion into our lives. However, their fragility makes them vulnerable to environmental changes, particularly extreme cold. When temperatures dip below freezing, the effects on fresh cut flowers can be swift and severe. Here’s what you need to know about the challenges posed by freezing conditions and the steps florists take to ensure blooms stay vibrant and fresh.

The Science of Cold Damage

Fresh cut flowers contain a high percentage of water, making them particularly sensitive to freezing temperatures. When exposed to subzero conditions, the water inside the cells of the flower petals, stems, and leaves can freeze, forming ice crystals. These ice crystals expand, rupturing the cell walls and causing irreversible damage. The result is often wilted, discolored, or mushy flowers that lose their aesthetic appeal and structural integrity.

Different flower varieties have varying levels of cold tolerance. For example, hardier flowers like chrysanthemums or carnations might withstand slight chills better than more delicate blooms like roses, tulips, or lilies. However, prolonged exposure to freezing conditions is detrimental to all cut flowers, regardless of type.

Steps Florists Take to Protect Fresh Cut Flowers

Florists understand the fragility of flowers and employ a variety of strategies to shield them from freezing temperatures:

  1. Temperature-Controlled Storage
    Florists use refrigerated storage systems that are carefully maintained at optimal temperatures (generally between 34°F and 38°F). These coolers are designed to keep flowers fresh without exposing them to the risk of freezing.

  2. Insulated Packaging
    During transportation, flowers are often wrapped in insulated materials or placed in boxes designed to provide a buffer against extreme temperatures. This is especially crucial for flowers being shipped long distances in cold climates.

  3. Heated Delivery Vehicles
    Florists who deliver flowers locally often use heated vans to prevent the blooms from freezing while in transit. This ensures that flowers reach their destination in perfect condition, even during harsh winter weather.

  4. Proper Handling Procedures
    Florists are trained to handle flowers with care. When temperatures drop, they minimize the time flowers spend outside of temperature-controlled environments, such as when unloading deliveries or transferring flowers to display areas.

  5. Selection of Seasonal Blooms
    In colder months, florists may prioritize stocking hardier flowers that are less likely to suffer from cold damage. Seasonal blooms are better adapted to withstand the environmental challenges of their natural growing periods.

  6. Educating Customers
    Florists also provide tips to customers on how to care for flowers in cold weather. For instance, they advise avoiding leaving flowers in cold cars, near drafty windows, or in unheated spaces.

How You Can Help Protect Your Flowers

As a consumer, you can play a role in keeping your flowers safe from the cold:

  • Act Quickly: If you’ve purchased or received flowers, bring them indoors as soon as possible.
  • Keep Them Warm (But Not Too Warm): Place your flowers in a stable environment away from drafts, heating vents, or freezing windows.
  • Use a Protective Covering: If you’re transporting flowers, cover them with paper or fabric to shield them from the cold.

Final Thoughts

Fresh cut flowers are a wonderful way to brighten any space, but they require special care in freezing conditions. Thanks to the expertise of florists and their careful handling processes, these delicate blooms can survive and thrive even in challenging winter weather. By understanding the impact of freezing temperatures and taking a few precautionary measures, you can ensure your flowers remain a beautiful and lasting part of your life.
