An arboretum within its landscape…

Initially a pastoral valley that had been abandoned for over 40 years, the arboretum as we know it today was recovered and nurtured into a unique example of a gardened landscape that extols the natural and agricultural spirit of its setting.

Classed remarkable garden

Arboretum de la Sedelle was awarded the title “Jardin Remarquable” by the Minister of Culture and Communication in 2005.

This label ensures a certain quality of garden under strict criteria such as the efforts made on their presentation, their public reception and their botanical or historical interest

Seasonal plant fair

The association “Les Jardins de la Sedelle” organises two annual weekend plant fairs at the Arboretum.

The spring fair is in May and the autumn fair in October. These plant fairs have become a regular rendezvous for plant and nature lovers of the region.

Next plant fair 11 & 12 May 2024

National maple collection

The plant collections

Not less than 400 species of trees and shrubs from 4 continents offer the visitor a sensual experience, plunging one into a magical world of marvellous plants.

Natural areas

A natural habitat is an ecological or environmental area where a specific species or community of species live. The development and conservation of the natural habitats within the arboretum is essential to its management. These areas are the reserves of biodiversity of the site and are the spaces that inspire the garden.
