Drawing on the story of the Baron de la Tour d'Aigues, the historic owner of the Hôtel de Caumont, a botanical enthusiast, the children discover the codes of the gardens «à la française» through their senses: touch, oïe, smell, sight and taste. Guided by our cultural mediators, the children explore the natural riches of these exceptional gardens thanks to the multiple activities of discoveries and games, then comes the time of the meeting with Philippe, the chief gardener of the Hôtel de Caumont, who playfully explains his natural working methods.
