Cérès Flore, unité de multiplication de végétaux dans le Vaucluse

Plant propagation in a controlled environment.

After 4 years of research and development, with the support of the Centre Wallon de Recherche Agronomique (CRA-W), Cérès Flore® has developed innovative techniques for the multiplication of native plants collected in natural environments..

The benefits of this solution

– Optimization of the germination rate, thus reducing the number of samples taken in the wild.
– Prevents the development of diseases on young plants.

Propagation and breeding

We use the entire range of horticultural techniques: cuttings, micro-cuttings and seedlings.

The plant material is subjected to a smothering misting system to strengthen its root system.
After a delay of 1 to 4 weeks, the plants are raised outdoors during their acclimatization and growth phase. This stage aims to subject the young plants to their future climatic conditions.

Depending on the origin of the species, they are raised directly at our production centers or at a partner nursery.
This service provider is selected according to its geographical position, to be as close as possible to the harvesting sites.
We give preference to partners based on social and ecological criteria, either small nurseries or ESATs with a horticultural section.
The signature of a breeding charter allows us to frame the conditions and the respect of the prescriptions that we formulate.

While the production of local plants is often limited in quantity, our innovative techniques allow many plants to be grown in record time and can therefore meet the growing demand for local plants.

ECOSUD – Cérès Flore®


We have developed a mobile traceability application that guarantees the origin of the plants produced.

The data collected in the field during the prospecting and sampling operations are digitized. The sites and their stations are georeferenced and the various attribute data collected are entered. During the sampling operation, a GPS point is recovered for each individual.

These geographic coordinates are used to feed our geographic information system (GIS) as well as a database containing elements such as the unique reference code, the species, its characteristics…
Archived on a secure server, these data are used during the production process.
The commercialized plan is thus provided with a QR code label including all the information, until the identification of the mother plant and its photograph on its place of taking.

Cérès Flore, application mobile de traçabilité des végétaux

We guarantee the origin of our plants.


We target a panel of diversified environments in order to best meet the demand:
wetlands, riverbanks, scrubland, coastline, forest and agricultural, within more than 85 000 Ha of natural sites.

In order to judge the degree of “naturalness” of the sampling site, we carry out a preliminary study on its history.
A regulatory and administrative analysis allows us to refine its potential.

Some of our approved collection sites.

We have signed multi-year agreements authorizing us to draw on all the land: from the Conseil départemental de l’Hérault, Vaucluse, Gard and Lozère; from the syndicat mixte du Bassin des Sorgues and the syndicat d’aménagement de la vallée de la Durance.

Our collection operations are carried out in soft mobility and are exclusively manual interventions.

Concerned about the environmental coherence of our production as well as the modalities of our interventions in natural areas, we take care to adapt our sampling programs to the management logic of the treated sites.
