How Long Do Preserved Flowers Last? Plus 4 Tips To Longer Life

Preserved flowers, with their unique blend of the natural beauty of fresh flowers and extended longevity, have become the top choice for adding beauty and elegance to home decor, gifts, and special occasions. 

This blog explores how long preserved flowers can last, what factors affect their lifespan, and whether they can last forever.

What Are Preserved Flowers?

Before delving into the durability of preserved flowers, it's important to understand what they are. Preserved flowers undergo a unique preservation process that maintains their natural beauty, texture, and vibrancy while removing the delicate freshness that can lead to quick wilting in natural flowers. 

They're often favoured for their long-lasting nature, eco-friendly qualities, and ability to retain the look and feel of fresh blooms without requiring daily maintenance.

How Long Do Preserved Flowers Last?

One of the preserved flowers' most prominent attractions is their lifespan. Compared to fresh flowers, which may last only a week or two, preserved flowers offer an impressive duration, with most arrangements lasting between one and three years. 

However, when cared for properly, preserved flowers can often retain their beauty for longer. Factors such as the type of preservation method used, the environment in which they're kept, and how well they're cared for significantly affect how long preserved flowers last. 

Generally, flowers preserved using high-quality methods will remain in prime condition for a more extended period, making them an excellent investment for both temporary and permanent displays.

Different Preservation Methods 

1. Glycerin Preservation

Glycerin preservation, a technique that replaces the natural sap within flowers with glycerin, allows the petals and stems to remain flexible and soft, giving them a more natural appearance over time. This method is particularly effective for flowers with thicker stems, such as roses or hydrangeas.

Steps:

1. Prepare a Glycerin Solution: Mix one part glycerin with two parts warm water in a container deep enough to hold the flowers upright.
2. Trim the Stems: Cut the stems at a diagonal angle to aid in better absorption of the glycerin solution.
3. Submerge the Stems: Place the stems in the glycerin solution, ensuring that at least the lower part of the stems is fully submerged.
4. Allow Time for Absorption: Leave the flowers in the solution for around two to three weeks, checking occasionally to see if the petals feel soft and flexible.
5. Display or Store: Once preserved, you can remove the flowers and arrange them as desired.

Longevity:

Glycerin preservation preserves flowers for one to three years with minimal fading. They maintain a soft and realistic texture, making this method ideal for arrangements that need a natural, lifelike appearance.

2. Freeze-Drying

Freeze-drying is a more advanced preservation technique often used by professionals to achieve long-lasting, vibrant results. This process requires special equipment but yields flowers that can last significantly longer and maintain a natural look.

Steps:

1. Pre-Treatment: Flowers are often treated with a stabilising solution to enhance colour retention before freeze-drying.
2. Freeze the Flowers: The flowers are placed in a freeze-dryer at a very low temperature to prevent colour loss.
3. Create a Vacuum: The freeze-dryer removes moisture from the flowers by creating a vacuum, effectively dehydrating them without affecting their shape.
4. Drying Process: The freeze-dryer raises the temperature slightly to convert any remaining ice into vapour, which is then removed.
5. Finishing: The flowers can be displayed or arranged after a few days in the freeze-dryer.

Longevity:

Flowers preserved through freeze-drying can last three to five years with proper care. They maintain vibrant colours and delicate textures, making this method ideal for premium floral displays or keepsakes.

3. Air Drying

Air drying is a simple and traditional technique suitable for preserving a variety of flowers. Though it does not retain colours as vibrant as other methods, this process works well for creating rustic, dried flower arrangements.

Steps:

1. Select Suitable Flowers: Choose flowers with sturdy and not overly delicate structures. Examples include lavender, eucalyptus, and roses.
2. Bundle and Tie: Gather each flower into small bunches and secure them with a string or rubber band.
3. Hang Upside Down: Hang each bundle upside down in a room temperature, well-ventilated area, away from direct sunlight, to prevent fading.
4. Allow to Dry: Leave the flowers to air dry for two to three weeks, depending on the flower type and environmental conditions.
5. Optional Spray: Once dried, you can spray the flowers with a light coat of hairspray for added durability.

Longevity:

Air-dried flowers typically last up to a year. Although they may lose some colour over time, they maintain their shape and structure, creating a classic, rustic look for decorative arrangements.

4. Silica Gel Drying

Silica gel is a granular substance that can absorb moisture from flowers, helping them retain their shape and colour. This method is especially effective for delicate flowers and those with intricate petal arrangements.

Steps:

1. Prepare a Container: Choose a container with an airtight seal and pour a layer of silica gel crystals at the bottom.
2. Position the Flowers: Place the flowers upright in the container, ensuring they are not crowded.
3. Cover with Silica Gel: Gently pour additional silica gel over the flowers, covering them entirely while avoiding bending or crushing the petals.
4. Seal the Container: Close the container tightly and store it in a dry place for one to two weeks.
5. Remove and Brush Off: After drying, carefully remove the flowers and brush off any remaining silica gel crystals with a soft brush.

Longevity:

Flowers preserved with silica gel typically last up to two years. They retain a vibrant appearance and detailed petal structure, though they may be more fragile than glycerin or freeze-dried flowers.

Each preservation technique offers unique advantages, so your choice will depend on the aesthetic you're aiming for, the types of flowers you're working with, and the longevity you need.

Factors Affecting The Longevity Of Preserved Flowers

Certain factors can impact the lifespan of preserved flowers, so it's essential to consider them.

1. Humidity – High humidity can cause preserved flowers to deteriorate more quickly. Avoid placing preserved flowers in bathrooms, kitchens, or areas with fluctuating humidity, as moisture can cause mould growth and reduce their lifespan.
2. Sunlight – Direct sunlight fades the vibrant colours of preserved flowers over time. Displaying preserved flowers in a shaded or dimly lit area will help maintain their vibrancy for extended periods.
3. Temperature – Extreme temperature variations can damage preserved flowers. Ideal temperatures are room-level or slightly cooler; avoid placing preserved flowers near heat sources like radiators, fireplaces, or windows with intense sunlight exposure.
4. Handling – While preserved flowers are less delicate than fresh blooms, excessive handling can still damage them. Avoid touching them too frequently, as oils from your hands can degrade the petals and leave marks.
5. Air Quality – Smoke and pollutants can degrade preserved flowers faster than clean air. Placing them in an environment free from dust and strong chemicals will help preserve their appearance.

How To Care For Preserved Flowers?

If you've invested in preserved flowers, proper care will ensure they last as long as possible. Here are some tips:

• Keep Them Dust-Free: Dust can accumulate on the surface of preserved flowers over time. Use a soft brush or gentle air blow to keep them clean.
• Avoid Watering: Unlike fresh flowers, preserved flowers do not require watering. Water exposure can damage preserved flowers, so ensure they stay dry.
• Limit Sun Exposure: As mentioned earlier, placing preserved flowers in a spot with indirect or no sunlight will prevent premature fading.

Why Choose Preserved Flowers?

Preserved flowers offer many benefits over fresh and artificial flowers. Here's why they make an excellent choice for various occasions:

• Longer Lasting Beauty: While fresh flowers may only last a week, preserved flowers retain their beauty for years, making them a cost-effective choice for decor and special events.
• Eco-Friendly: Since preserved flowers have an extended lifespan, they require fewer replacements, reducing waste and the carbon footprint associated with repeated purchases of fresh flowers.
• No Maintenance: Unlike fresh flowers, which need water and care, preserved flowers are virtually maintenance-free, making them ideal for busy individuals who still want to enjoy floral decor.

Conclusion On How Long Preserved Flowers Last

To summarise, preserved flowers can last several years with proper care, often maintaining their beauty for one to three years on average. Although they do not last forever, their extended lifespan and ease of care make them a highly desirable option for floral enthusiasts. 

With minimal maintenance, these flowers can bring a touch of nature into spaces for years, creating a lasting impression and reducing the need for constant replacements. 

So, if you're considering preserved flowers, they're undoubtedly worth the investment for their beauty, sustainability, and unique ability to add charm to any setting.

Frequently Asked Questions About How Long Preserved Flowers Last

Do Preserved Flowers Last Forever?

Over time, the colours may fade slightly, and the texture may become more fragile. However, in comparison to fresh flowers, preserved blooms provide a far more extended lifespan and can remain beautiful for several years.

For instance, some premium preserved flowers last up to ten years with minimal degradation if kept in optimal conditions. Nevertheless, despite their resilience, they will eventually show signs of age.

Are Preserved Flowers Safe For People With Allergies?

Yes, preserved flowers are generally safe for people with allergies. Unlike fresh flowers, preserved flowers do not release pollen, making them a more suitable option for individuals who may be sensitive to pollen. 

Since the preservation process removes moisture, preserved flowers are less likely to attract mould or other allergens that can grow on fresh plants.

Can Preserved Flowers Be Used Outdoors?

Preserved flowers are best kept indoors. Exposure to outdoor elements, such as direct sunlight, humidity, rain, and wind, can quickly damage preserved flowers, causing them to fade, disintegrate, or lose their shape. 

If you wish to use them in an outdoor setting temporarily, ensure they’re in a sheltered spot, but long-term outdoor display is not recommended.

Are There Scented Options For Preserved Flowers?

Yes, some preserved flowers are infused with fragrance during the preservation process to mimic the scent of fresh flowers. 

However, the fragrance may diminish over time, depending on environmental conditions. If you’d like to add or refresh the scent, consider using a light floral spray or essential oil, but apply it sparingly to avoid damaging the petals.

Do Preserved Flowers Decompose Naturally?

Preserved flowers do not decompose as quickly as fresh flowers due to the chemicals and processes used to maintain their appearance. However, they are still made of natural plant material and will eventually decompose if exposed to moisture or left in conditions conducive to organic breakdown.

Are Preserved Flowers Worth The Investment?

Given their long-lasting nature and low maintenance, preserved flowers offer great value for those who appreciate their beauty but don't want to deal with the upkeep. While they may cost more upfront than fresh flowers, their extended lifespan more than justifies the investment.

Preserved flowers can be a beautiful addition to homes, wedding decor, and gifts. Their longevity makes them a memorable keepsake, and they often carry sentimental value, especially when gifted for special occasions.
