History and origin of preserved plants

Preserved plants, flowers and trees are 100% natural. Plant preservation is a totally ecological process that replaces the natural sap of the flower by a preservative.

That substance is close to sugar and is 100% biodegradable. Thanks to that natural preserving technique, preserved plants and flowers retain their flexibility and their natural freshness without any maintenance. They require no watering, no special treatment or luminosity. These plants and flowers are ideal for weddings, unique gifts, home décor, fashion accessories and innovative products.

 

A BIT OF HISTORY

The first patents related to preservation date back to the 1970’s. Several methods have been developed with varying levels of success. For instance, lyophilisation has overshadowed preserved plant for a long time as they were wrongly compared.

In the 1980’s, an association between a Swedish, a French and an Italian scientists democratised preserved plants. Together, they managed to develop sophisticated technologies enabling the implementation in France of a real preservation factory. The appearance of vertical gardens and preserved roses on stem has raised public awareness toward preserved plants.

 

THE PROCESS 

For the best results, plants are preserved at the time of their life cycle when they display their most beautiful appearance. They are harvested in optimal conditions with the respect of environment their natural renewal process. They are then sorted before entering the preservation room, positioned in gutters – with their base immersed. During this step, the sap of the plant evaporates to give way, after a few days, to the new liquid – a mixture of vegetable glycerine, water, and substrate and food colourant. Before a final quality control, plants are rinsed then dried. They are then ready for use. This overall process can last between 7 and 20 days depending on the size of the plant. Each plant has its own preservation specificities: time, temperature of the preservative, ambient temperature, water quality, raw material, type of substrate… So it is not possible to preserve a plant outside its window of opportunity. This makes stock management quite complex, but still less complicated than it is with fresh plants.
