Selecting Flowers for Outdoor Durability
When designing for an outdoor event, florists must consider environmental factors that indoor arrangements never face. Direct sunlight, wind, occasional rain, and fluctuating temperatures can cause delicate flowers to wilt, discolor, or shatter prematurely. The most durable flowers for these settings share common traits: sturdy stems, thick petals, and a natural tolerance for warmer conditions. Selecting the right blooms is the first critical step in creating installations, centerpieces, and bouquets that remain vibrant from the ceremony through the final toast.
Top Florist-Recommended Durable Blooms
Based on industry experience and handling characteristics, these flower varieties consistently perform well outdoors.
Chrysanthemums: Often called "mums," these are a cornerstone for outdoor work. Their many petals are tightly packed and robust, resisting damage from wind and holding moisture well. They are available in a wide color range and have an exceptionally long vase life.
Carnations: Modern carnations are far from old-fashioned when it comes to durability. Their ruffled, somewhat waxy petals do not dehydrate quickly, and they maintain their form reliably in sun and heat. They are a cost-effective and resilient choice.
Alstroemeria: Known for its longevity, alstroemeria features multiple blooms per stem and strong, flexible stems that hold up in arrangements. The flowers are less prone to dropping petals and can handle mild temperature swings.
Solidago (Goldenrod): This hardy filler flower adds volume and texture. Its tiny, clustered blooms are very resilient to environmental stress and provide a natural, garden-style look that suits outdoor settings.
Succulents: While not a cut flower, succulents are increasingly incorporated into event designs for their extreme drought tolerance. They can be used as living accents in centerpieces or bouquets and often last for weeks after the event.
Certain Roses: Select rose varieties, particularly garden roses or those with thicker petals, can be suitable. However, they require excellent conditioning and some shade. Avoid tightly budded roses, as they may not open in cooler evening temperatures.
Hypericum Berries: These berry sprigs add color and structure. Their waxy berries do not wilt and provide visual interest even if some flowers begin to fade.
It is important to note that availability and peak condition for these flowers vary by season and region. Consulting with a local grower or wholesaler about what is currently at its hardiest is always a recommended practice.
Essential Conditioning and Hydration Tips
Choosing durable flowers is only half the battle; proper preparation is what unlocks their full potential outdoors.
- Thorough Hydration: Upon receipt, recut all stems at an angle and place them in a clean bucket of fresh water and floral food. Allow them to hydrate in a cool, dark place for several hours or preferably overnight before designing.
- Maximize Water Uptake: For woody stems like certain chrysanthemums, split the stem ends or use a hammer to gently crush them. This dramatically increases the surface area for water absorption.
- Use Floral Food: Professional floral food is non-negotiable for outdoor events. It provides nutrients, lowers water pH to improve uptake, and inhibits bacterial growth that can clog stems.
- Avoid Direct Water on Blooms: When hydrating, and if misting, avoid getting water on the petals of flowers like roses and carnations, as this can cause spotting or promote botrytis (gray mold), especially in humid conditions.
Mechanics and Design Strategies for Outdoors
The construction of the arrangement is as important as the flower selection. Florists employ specific techniques to combat the elements.
- Secure Mechanics: Use multiple points of support. For installations and large centerpieces, secure foam or chicken wire firmly in the container. For bouquets, bind stems tightly and use additional wraps or supports.
- Wind Considerations: Create lower, denser centerpieces rather than tall, top-heavy designs that can act as sails in the wind. Use sturdy blooms as anchors within the design.
- Shade and Timing: If possible, place arrangements in dappled shade or use market umbrellas to protect them from the harshest midday sun. Deliver and setup as close to the event start time as feasible.
- Water Sources: For any design not in a hidden water source, such as an arch or wreath, use water tubes for individual stems to keep them hydrated throughout the event.
By combining resilient flower varieties with professional-grade conditioning and sturdy design mechanics, florists can create beautiful outdoor event flowers that are built to last. Always communicate with clients about the realistic expectations for flowers in an uncontrolled environment, as even the most durable blooms have their limits.
