The floral decoration of the Monument, the Builidng of the Domes and the Orangerie requires a very large-scale production of flowers for cutting. These flowers are grown in a garden strictly reserved for them.

This garden itself is lined with 100 climber rose-trees. The configuration of the garden is designed around 12 panels delimited by a row of 240 apple trees and 220 Queen Elizabeth rose-trees.

Each panel makes it possible to cultivate a great variety of flowers which we find in the magnificent floral compositions produced by the Floral Workshop depending on the season.

The production of flowers for winter decoration is completed by flowers grown in greenhouses.
