Plant preservation process

At Greenmood, we use innovative preservation techniques to transform natural plants into long-lasting biophilic design elements without light, water or maintenance.

From freeze-drying to natural stabilization

Preservation techniques first appeared in the 1970s, starting with freeze-drying. Flowers were frozen, then dried through sublimation under vacuum. This process extended their lifespan without damaging their form.
Over time, more effective methods emerged, focusing on replacing plant sap with natural glycerin. These innovations opened the door to preserving a wider variety of species with greater efficiency.

A solution made for interior design

Today, our preservation process maintains the plant’s color, shape and flexibility for years. It allows designers to integrate natural elements into spaces where live plants would struggle.
From moss walls to acoustic installations, preserved plants offer the calm of nature — without constraints or upkeep.This evolution has allowed architects and designers to integrate real plant elements into spaces that were once too harsh or impractical for living greenery.

Preserving plants is how we bring nature into everyday interiors.

Different types of plant stabilization

Preservation methods vary depending on the type of plant, but all aim to maintain texture, color and flexibility without the need for soil, water or light.

Substitution technique for leafy plants

For branches and leafy plants, the stems are placed in a glycerin-water solution. As the sap naturally evaporates, the preservation liquid is absorbed into the plant over 1 to 3 weeks.
The process is carried out in a controlled environment to ensure the right temperature, humidity and glycerin concentration for each species.

Rehydration technique for mosses and lichens

Mosses are first dried, then misted with a warm glycerin solution. Lichens are soaked in saltwater baths before drying.
Once rehydrated, they’re placed in a climate-controlled room, allowing moisture to evaporate gradually while preserving their softness and shape.

Every plant type has a tailored method to preserve its natural beauty.

Plants preserved with vegetable glycerin

We use plant-based glycerin to naturally stabilize preserved foliage, the same ingredient found in cosmetics, food, and pharmaceutical products.

A safe and sustainable compound

Vegetable glycerin is biodegradable, odorless, colorless and non-toxic. It’s derived from oils like rapeseed during soap production and valued for its ability to retain moisture and stabilize liquids.
These properties are key in preservation, allowing us to keep plants flexible, soft and vibrant for years.

Preservation without additives

Our solution is made from pure vegetable glycerin and water, with no artificial chemicals or coatings. It gradually replaces plant sap during the stabilization process, locking in the plant’s natural look.
This ensures our products remain eco-conscious, safe and visually authentic.

Glycerin is what keeps preserved plants naturally fresh and soft to the touch.

What are the benefits of a stabilized plant?

Preserved plants offer all the beauty of nature, without the hassle of watering, pruning or replacing.

Long-lasting and low-maintenance

Stabilized plants keep their shape, texture and flexibility for up to 7 years. They require no water, sunlight or treatments, making them ideal for offices, retail spaces, hospitality or any indoor environment.
They stay vibrant while reducing upkeep and operational costs over time.

Creative freedom for designers

Because they are maintenance-free, preserved plants can be used in ways live plants can’t: green walls, acoustic panels, furniture inlays, or vertical gardens in dimly lit areas.
This flexibility supports bold and innovative interior concepts without compromising on durability.

Preserved plants allow design to meet nature with complete freedom.

Are stabilized plants ecological?

Stabilized plants are more efficient, sustainable and durable than living decorative plants.

Higher yield, lower waste

For live plants, up to 80% are lost before installation. With preservation, that number flips: 80% of harvested plants are used, thanks to local processing right after harvest.
They don’t require transport in climate-controlled packaging or constant replacements after installation.

Zero resource use after installation

Once in place, preserved plants need no water, fertilizer or care. They last for years, reducing consumption and minimizing environmental impact.
This makes them a smart choice for eco-conscious projects with long-term visio

Preserved plants offer a more sustainable way to design with nature.
