Inside Our Plant-Based Preservation Process
Direct answer
Preserved flowers begin as real flowers, but they are treated differently from a fresh bouquet or an air-dried bloom. In the LULU ROSÉE process, the flower’s natural sap is replaced with a plant-based preservation solution. The goal is to retain the dimensional appearance and soft visual character of the original flower without placing it in water after delivery. The treated flowers are then arranged by hand into the chosen box, vase or display design. LULU ROSÉE does not publish a detailed formula, ingredient list or exact treatment schedule, so this guide explains only the confirmed process—not an invented recipe. Once arranged, the flowers belong indoors, away from water, direct sunlight, high humidity and rough handling.
The confirmed process at a glance
| Stage | What LULU ROSÉE confirms | What this guide does not claim |
|---|---|---|
| 1. Real flower | The material begins as a genuine flower, not a fabric or molded imitation. | A named farm, cultivar or universal harvest schedule. |
| 2. Preservation treatment | Natural sap is replaced with a plant-based preservation solution. | A complete ingredient list, concentration, timing or technical formula. |
| 3. Design | The preserved flowers are arranged by hand. | One identical result from every natural bloom. |
| 4. Display | The finished arrangement requires no watering. | That environmental conditions no longer matter. |
| 5. Longevity | LULU ROSÉE designs its preserved roses to last 3+ years with proper care. | A fixed lifespan in every room, climate or handling condition. |
What “preserved” means
Preservation is a broad term for methods intended to keep plant material useful for display after it would otherwise lose its fresh appearance. Different methods produce different results. Pressing flattens flowers. Air-drying removes moisture and often creates a more brittle texture. Desiccants and freeze-drying are other established approaches. Solution-based preservation can replace water within plant tissue with another material to help it remain more pliable.1
University extension guidance illustrates why “preserved” and “dried” should not be treated as perfect synonyms. Kansas State University describes glycerin-based preservation of decorative plant material as replacing some water in fresh tissue and helping the final material remain soft and pliable, while noting the brittle character associated with dried flowers.1 University of California guidance similarly describes plant material absorbing a glycerin solution that replaces water content and helps it remain supple.2
These sources explain general horticultural methods. They are not descriptions of LULU ROSÉE’s complete formula. The brand-confirmed statement is narrower: natural sap is replaced with a plant-based preservation solution.

How preservation differs from simply drying a flower
Both processes extend the decorative life of natural plant material, but they do so differently.
| Question | Preserved flower | Dried flower |
|---|---|---|
| Is it made from a real flower? | Yes | Yes |
| Main idea | Treatment is used to retain more of the flower’s dimensional, supple character. | Moisture is removed through air, desiccant, pressing, heat, freeze-drying or another drying method. |
| Typical visual result | Often closer to the volume and appearance associated with the original bloom. | Often more muted, crisp, papery or intentionally aged, depending on method. |
| Water after processing | No | No |
| Best choice | When the buyer wants a real flower with a fresh-like presentation. | When the buyer prefers a natural, textural or visibly dried aesthetic. |
Research on preserved rose flowers also demonstrates that treatment method affects the finished form. A 2008 horticultural study comparing glycerin-treated rose flowers with several drying methods found that selected glycerin treatments retained flower size more closely than the tested air-, silica-, freeze- and hot-air-drying methods.3 That result supports the general distinction between solution-preserved and dried flowers, but it does not establish the ingredients or performance of LULU ROSÉE’s process.
Neither category is automatically “better.” A dried arrangement can be beautiful precisely because it looks dried. A preserved arrangement serves a different preference: the viewer wants the flower to keep more of the dimensional presence associated with a fresh bloom.
What “plant-based preservation solution” tells you—and what it does not
The phrase identifies the preservation solution used to replace the flower’s natural sap. It helps explain why the finished material is neither a fresh-cut flower in water nor an artificial flower made from fabric or molded material.
The phrase does not disclose every ingredient or certify a wider set of product attributes. Without supporting documentation, it should not be stretched into claims about the complete formulation, human or pet exposure, environmental impact, agricultural inputs or disposal. Clear limits make the explanation more useful: readers know what has been confirmed and what has not.
Why the finished arrangement does not need water
A fresh-cut flower continues to rely on water after cutting. A preserved flower has already undergone treatment for decorative display. LULU ROSÉE therefore instructs customers not to water the finished arrangement.
Adding water is not a way to “refresh” it. The more useful care routine is environmental: keep the arrangement indoors, avoid direct sunlight and high humidity, and minimize touching or movement. Those conditions help protect the petals, the arrangement structure and the vessel presentation.
For the complete after-delivery routine, follow the preserved rose care guide.
Hand arrangement is a separate part of the process
Preservation prepares the floral material; it does not create the finished composition. LULU ROSÉE arrangements are handcrafted, which means the maker still has to consider flower direction, spacing, color distribution, silhouette and the relationship between the flowers and their vessel.
Natural variation remains visible. Two real blooms may not open to the same degree or carry color in exactly the same way. Hand arrangement allows those differences to become part of a balanced design instead of requiring every flower to look mechanically identical.
Frequently asked questions
Are preserved flowers real?
Yes. LULU ROSÉE preserved flowers begin as real flowers. Preservation changes how the natural material is prepared for display; it does not turn an artificial flower into a natural one.
Are preserved flowers the same as dried flowers?
No. Both use real plant material and both are displayed without water, but the methods and intended results differ. Dried flowers are defined by moisture removal. Solution-preserved flowers are treated to retain more pliability and a fresh-like dimensional appearance.
Do LULU ROSÉE preserved flowers need water?
No. Do not water them. Place the arrangement indoors, away from direct sunlight and high humidity, and handle it gently.
Does “plant-based” describe the complete formula?
No. It describes the preservation solution confirmed by LULU ROSÉE. The brand has not published a complete ingredient list in this guide, so no broader formulation, exposure or environmental conclusion should be inferred.
Why can two arrangements show small differences?
They are made with real flowers and arranged by hand. Slight differences in petal shape, bloom size and tone are normal characteristics of natural material. The design standard is a harmonious overall composition, not exact duplication.
How long will the finished flowers last?
LULU ROSÉE preserved roses are designed to last 3+ years with proper care. Room conditions and handling matter, so the statement is not an identical-outcome promise for every setting.
From real flower to lasting design
The most accurate explanation is also the simplest: a real flower is preserved by replacing its natural sap with a plant-based solution, then arranged by hand and displayed without water. The process helps retain the flower’s visual presence; proper care protects the result.
