What Are Preserved Flowers and How to Preserve Flowers Forever — Learn How Real Flowers Are Preserved, Dried, and Last for Years by ZESO Blooms
What Are Preserved Flowers? The ZESO Process & Benefits.
ZESO preserved blooms are 100% real flowers, harvested at their peak and preserved through a proprietary, non-toxic treatment using plant-based glycerin and eco-certified, food-safe dyes.
The glycerin replaces the flower’s natural sap, helping it retain its original softness and shape. Coloring is achieved using food-grade dyes—the same types commonly found in candies, beverages, and ice cream. This ensures long-lasting color while remaining safe to touch and non-irritating to skin.
Each preserved bloom is crafted with biodegradable materials in an eco-conscious environment. ZESO is actively working toward a carbon-neutral supply chain, committed to sustainable beauty that respects nature—from farm to your home.
ZESO Blooms: How We Preserve Nature’s Best
The ZESO Difference: Our Sourcing & Harvesting
ZESO preserved blooms begin their journey in high-elevation flower farms near the 25th parallel north. These farms enjoy a rare combination of over 2,200 hours of annual sunlight, year-round mild temperatures, and a long, frost-free growing season.
This naturally balanced environment minimizes the need for artificial interventions, allowing roses to flourish with consistent shape, vivid color, and a healthy petal structure.
Each bloom is 100% real and carefully hand-harvested at peak maturity, just before full bloom. At this moment, the petals are most supple, and the color is richest—ideal for entering the next phase of preservation.
The ZESO Process: Gentle Dehydration
Once harvested, each bloom enters a controlled dehydration phase. Unlike traditional drying, this process gently extracts the flower’s natural sap without applying heat, allowing the bloom to retain its original structure and cellular integrity.
The flowers are placed in a low-humidity environment, where moisture is gradually reduced. During this step, over 50% of the harvested flowers are removed due to minor imperfections—ensuring only the most pristine specimens move forward.
This step lays the foundation for lasting softness and vibrant shape, all while preserving the authenticity of the natural flower. Discarded flowers are not wasted; most are redirected for culinary or secondary uses, reflecting ZESO’s food-grade standards throughout the entire preservation workflow.
The ZESO Process: Rehydration & Color Infusion
After dehydration, the selected blooms are placed in a nutrient-rich solution composed of plant-based glycerin and food-grade colorants—such as turmeric or betanin. This formula replaces the extracted sap, rehydrating the flower from within and preserving its original flexibility and structure.
This step not only softens the petals but also infuses them with long-lasting color. While many hues are added for visual impact, white preserved roses remain untouched, showcasing their pure, unaltered state.
The infusion process takes several days under tightly regulated conditions to ensure non-toxicity and color stability across years of display. This is the moment the bloom transitions from fragile to eternal.
The ZESO Process: Final Drying & Finishing
Once the blooms are fully rehydrated and infused, they undergo a carefully controlled drying phase. This stage stabilizes the internal moisture content, locking in the softness, shape, and hue achieved in earlier steps.
Flowers are placed in humidity- and temperature-controlled chambers for 5 to 7 days, allowing the glycerin and dyes to distribute evenly and bind naturally. No heating or baking is involved—the process mimics natural air-drying in an optimized environment.
After drying, each bloom is hand-inspected for quality. Only roses that meet strict standards in form symmetry, petal flexibility, and color consistency are selected for packaging. On average, only 40% of blooms harvested reach this final stage, ensuring every ZESO bloom embodies natural beauty, technical precision, and lasting impact.
The ZESO Process: Packaging & Preservation Integrity
After passing final quality checks, each preserved bloom is carefully packaged to ensure long-term stability and protection. The packaging process is critical for maintaining the flower's structural integrity and visual quality during storage and transportation.
Each bloom is placed into shock-resistant, moisture-controlled packaging, including kraft boxes or transparent protective casings. These materials are selected to:
- Prevent deformation during transit
- Minimize exposure to ambient humidity and ultraviolet light
- Reduce mechanical abrasion and impact
The entire production process—from harvest to final sealed packaging—is typically completed within 10 to 15 days.
Following preservation, the blooms are transformed into floral arrangements and artistic compositions, serving as high-quality, safe, and enduring materials.
ZESO is now bringing these remarkable creations to the world. While fresh flowers are beautiful, we believe that these science-enhanced blooms possess a timeless and irresistible charm of their own.

Frequently asked questions
Yes, preserved flowers are 100% real flowers. They are harvested at their peak and undergo a special, non-toxic preservation process that uses plant-based glycerin and food-safe dyes. This process replaces the flower's natural sap, allowing it to retain its original softness, color, and shape for years.
The key differences between preserved flowers and other types are:
- vs. Fresh Flowers: Preserved blooms last 2 to 5 years, while fresh flowers wilt within a week. They require no water or sunlight.
- vs. Dried Flowers: Preserved blooms remain soft and flexible. Dried flowers are also real, but they are dehydrated by air or heat, making them brittle and faded.
- vs. Artificial Flowers: Preserved blooms are made from real flowers, not synthetic materials like plastic or silk. They look and feel more natural and are a more sustainable option.
Preserved flowers typically last 2 to 5 years, depending on the environment and care. In stable indoor conditions, their color, softness, and shape can remain intact for many years without fading or drying out.
To maximize their lifespan, proper care is essential:
- Keep them dry: Avoid moisture or high humidity. Preserved flowers are sensitive to water and should never be placed in vases.
- Avoid direct sunlight: Prolonged exposure to sunlight can cause fading over time.
- No watering required: Preserved flowers are maintenance-free; watering them will damage their structure.
- Minimal handling: Although they are soft and real, frequent touching can cause petals to lose shape.
- Keep away from heat: Avoid placing them near heaters or radiators.
With proper care, ZESO preserved flowers remain a beautiful and lasting part of your space.
ZESO preserved flowers are unscented by default. During the preservation process, the natural fragrance is removed to ensure the flower's stability.
However, you can safely add fragrance if desired:
- Use light floral mist sprays or essential oil diffusers nearby.
- Avoid direct spraying of heavy oil-based perfumes, as they may cause discoloration or residue buildup on the petals.
- For best results, spray from a distance or apply fragrance to nearby materials like preserved moss or ribbon.
Adding fragrance is optional, and many clients appreciate the clean, neutral presence of preserved flowers, especially in allergy-sensitive environments.
Yes, ZESO preserved flowers are completely safe to touch and display indoors. Our preservation process uses non-toxic, eco-certified ingredients—including plant-based glycerin and food-grade dyes. This makes the flowers skin-safe and non-irritating, and suitable for homes, offices, or event spaces.
A few tips for handling and display:
- Gently touch the petals or stems, avoiding excessive pressure.
- Keep flowers away from direct sunlight, high humidity, and strong airflow to prevent fading.
- Avoid all contact with water; preserved flowers do not need watering, and moisture may cause damage.
Thanks to their natural softness and preserved shape, ZESO blooms are ideal for indoor arrangements, display cases, and even enclosed art pieces.
Preserved flowers may be new to many consumers, but the technology is not. The preservation process was originally pioneered in Japan over 30 years ago in the early 1990s.
- The goal was to create "stabilized flowers" that retained the softness, shape, and color of real flowers for years.
- The market began to grow in Japan and France before spreading more widely in the last 5-10 years.
ZESO uses next-generation preservation techniques that build on this legacy, offering flowers that remain soft, safe, and stunning for years, without the need for water or maintenance. While still considered a relatively new product category, preserved flowers are now widely embraced by designers, florists, and lifestyle brands around the world.

Yes, ZESO preserved flowers are completely safe for indoor display around children and pets when used as intended.
Our preservation formula uses plant-based glycerin and eco-certified, food-safe dyes—the same types often found in candies and beverages. The flowers are non-toxic to the touch and free from irritating chemicals.
However, as with any decorative item, we recommend the following safety tips:
- They are not intended for consumption.
- Loose petals or small components may pose a choking hazard if handled improperly by very young children or animals.
- For optimal safety, we recommend placing preserved blooms in locations out of reach of pets or unsupervised toddlers.
ZESO preserved flowers are allergen-conscious, pollen-free, and safe for sensitive users. Compared to fresh-cut flowers, they carry a much lower risk of causing allergic reactions or skin irritation.
Key Points:
- No Pollen Exposure: Unlike fresh flowers, ZESO blooms are harvested before full pollen maturity and do not release airborne pollen—the main trigger for floral allergies like hay fever.
- No Fragrance Chemicals: Fresh flowers often contain volatile organic compounds (VOCs) that can trigger allergies. ZESO preserved flowers do not contain added fragrances or natural volatile oils.
- Non-toxic, Hypoallergenic Materials: The preservation solution uses plant-based glycerin and food-grade colorants, both widely used in skincare and food products.
- No Mold, Mildew, or Biological Decay: Unlike fresh flowers that can harbor mold spores as they degrade, ZESO blooms are stabilized and do not rot.
