About Les Botaniques
Les Botaniques — edition 2026
The 2026 edition of Les Botaniques de Chaumont-sur-Loire will take place on Saturday, September 19th and Sunday, September 20th at the Domaine de Chaumont-sur-Loire. 24 specialist nursery growers from across France and Belgium, along with four garden artists and artisans, will be showcasing their collections. The program includes four lectures, and the "Coup de Cœur des Botaniques" award will be presented on Saturday at 2:00 PM. The weekend coincides with the European Heritage Days.
A plant exhibition and sale
On September 19th and 20th, 2026, nursery growers brought together by the Plantes et Cultures association will set up their stands at the Domaine de Chaumont-sur-Loire. 24 producers from various French regions and Belgium will be selling their cultivated collections: specialized varieties, rare or heirloom plants, species for dry or wet environments, citrus, bamboo, ferns, conifers, peonies, roses, carnivorous plants, aquatic plants, and wild-origin native species.
Four lectures
On Saturday, Pascal Garbe will discuss garden flavors at 11:15 AM, Bénédicte and Michel Bachès will share the history and diversity of citrus fruits at 3:00 PM, and Pierre-Alexandre Risser will present "A garden that reflects me" at 4:30 PM. On Sunday at 3:00 PM, Baptiste Pierre will explore the sexuality of plants at the Potager Extraordinaire.
The Coup de Cœur des Botaniques award
The award will be presented on Saturday, September 19th at 2:00 PM by a jury of plant industry experts. It recognizes a plant for its botanical or horticultural originality, aesthetic quality, and vigor ("Côté Jardin"), and an exhibitor for the quality of their stand presentation and the information provided to the public ("Côté Cour").
Artists and artisans
Four exhibitors round out the event: nesting boxes and pollinator hotels, drawings and watercolors, garden furniture and metal sculptures, and irrigation ceramics.

Les Botaniques: An Exceptional Plant Festival
Les Botaniques de Chaumont-sur-Loire is a unique event dedicated to rare and exceptional plants. Held every autumn at the Domaine de Chaumont-sur-Loire, this plant festival brings together the best nursery owners and plant collectors from France and Europe in an exceptional heritage setting overlooking the Loire.
A Partnership with the Best Nursery Owners
Established in 2019, Les Botaniques is organized in partnership with the association Plantes et Cultures, which brings together selected nursery producers known for the quality of their collections and their botanical expertise. Each edition gathers around 25 exhibitors, exceptional nurseries, and creators of high-quality plant collections.
The Star Plants of the Garden Festival
Les Botaniques create a link between plants and gardens, highlighting the star plants that make up the ephemeral gardens of the International Garden Festival. It's a unique opportunity to discover, purchase, and discuss remarkable varieties used by landscape designers from around the world in their creations at Chaumont.
Coup de Coeur Prize and Botanical Encounters
Each edition awards a Coup de Coeur Prize recognizing a nursery owner for the excellence of their collection or the originality of their plant creations. The festival also offers meetings, conferences, and discussions with producers, allowing gardening enthusiasts to deepen their knowledge and discover exceptional varieties.
The Allée des Ormeaux: A Botanical Setting
The festival takes place in the Allée des Ormeaux, a former bridle path in the heart of the Domaine de Chaumont-sur-Loire. This green and shaded setting provides an ideal environment for presenting plants and for visitors to stroll, creating a friendly and intimate atmosphere conducive to exchanges between plant world amateurs and professionals.
